Update 01.135 - Bug Fixes and Improvements

This week's update brings you several improvements for modders that we've merged from our community on GitHub, plus more bugfixes. From Tyrsis we have production API changes and terminal changes, so modders can now create their own terminal interfaces such as buttons, sliders, etc. Another addition is Malware's Ship Data update and remote control fixes that makes Coop mode work when a conveyor block (or any block that doesn't have an owner) is between the master and slave assemblers. And last but not least, we have Rexxar's projector ModAPI changes which have added more ModAPI interface to the projection API.
Our GitHub source code has also been updated.
Many thanks to our entire community for helping us develop the game and raise the bar for modding possibilities. We're simply in awe of all the mods and creations you guys publish on the Workshop :)

Update 01.134 - Animation & Testing Modding Tool

Hey Engineers! In this week's update, we're bringing you a few important bug fixes. We fixed the autopilot not being able to turn itself off, and not being able to descend below 60 meters on Planets. We also fixed piston heads, rotor heads, and wheels detaching when reloading a world. Keep in mind that we're also working hard on optimizations and the netcode behind the scenes. This week we've also included something extra for modders - a Testing Tool and Animation Modding Tool.
Our new animation system includes the Animation Controller Editor, which allows modders to create animation controllers in a graphical user interface and even debug them live in the game. Keep in mind that for now, this tool is only for character animation modding.
Testing Tool is a simple application for recording and playing back a saved game. It was originally created for internal use to help us test scenarios and understand how things work in the game, but modders can use the tool to help them see how changes to their code, mods, or scripts can affect the outcome of a particular saved game. The tool can also be used by anyone who has a Keen Software House game to run and play back your games, and to give us your feedback.

About This Game

Space Engineers is a sandbox game about engineering, construction, exploration and survival in space and on planets. Players build space ships, space stations, planetary outposts of various sizes and uses (civil and military), pilot ships and travel through space to explore planets and gather resources to survive. Featuring both creative and survival modes, there is no limit to what can be built, utilized and explored.

Space Engineers features a realistic, volumetric-based physics engine: everything in the game can be assembled, disassembled, damaged and destroyed. The game can be played either in single or multiplayer modes.

Volumetric objects are structures composed from block-like modules interlocked in a grid. Volumetric objects behave like real physical objects with mass, inertia and velocity. Individual modules have real volume and storage capacity.

Space Engineers is inspired by reality and by how things work. Think about modern-day NASA technology extrapolated 60 years into the future. Space Engineers strives to follow the laws of physics and doesn't use technologies that wouldn't be feasible in the near future.

Space Engineers concentrates on construction and exploration aspects, but can be played as a survival shooter as well. We expect players will avoid engaging in direct man-to-man combat and instead use their creativity and engineering skills to build war machines and fortifications to survive in space and on planets. Space Engineers shouldn’t be about troops; it should be about the machinery you build.

Early Access

    - Two Platforms – competitive two-team multi-player world
    - Asteroids – start in a rescue ship with very limited resources
    - Empty World – no asteroids, no ships; suitable for creative mode
  • Enemy NPCs
    - sabiroids (spiders): can be found on alien planets and on Titan moons. They can destroy metal blocks and attack players. Their favorite hunting strategy is hiding in the ground and un-burrow to surprise their prey. When players kill a spider, new spiders won’t appear in the area for some time. They also store some components inside their bodies from objects and blocks that they consumed.
    - pirate bases: can be found either in space or occupying planetary surface. They have bounty hidden inside their containers that players can loot if they get over the drone attacks.
    - enemy drones: they spawn automatically from pirate bases and attack the players when they venture into pirate territory
  • Ships (small and large ships – build them, pilot them and crush them
  • Space stations
  • First-person & Third-person
  • Planetary bases, outposts, cities!
  • Dedicated servers - allow players to connect to a third party host, rather than using a player-host, in a peer-to-peer set-up. The result is a faster connection and a more fluent multiplayer performance with less lag
  • Super-large worlds – the size of the world to 1,000,000,000 km in diameter (almost infinite)
  • Procedural asteroids - adds an infinite number of asteroids to the game world
  • Exploration - adds an infinite number of ships and stations to the game world; discover, explore, acquire and conquer!
  • Drilling / harvesting
  • Manual building in survival mode – use welder to assemble blocks from components; use grinder to disassemble and reuse components
  • Deformable and destructible objects – real proportions, mass, storage capacity, integrity
  • Scenario editor - players can create missions and game modes which can be played by other players. Capture the flag, deathmatch, racing or campaign driven missions - all can be done by using the scenario editor, with your own rules and designs
  • Building blocks - light armor (cube, slope, corner), heavy armor, interior wall, interior light, small cockpit, large cockpit, cargo container(s), drill (character, large/small ship), ore detector, gravity generator, nuclear reactor, thruster, gyroscope, assembler, medical room, magnetic landing gears, spotlight, catwalk, cover wall, stairs, ramp, window(s), pillar, decoy, wheels, automated turrets, weapons, artificial mass, conveyor, collector, connector, merge block, camera, sensor, timer, text panel
  • Magnetic landing gears – attach your ship to a surface (another ship or asteroid)
  • Electricity - all blocks in a grid are wired in an electrical and computer network; electricity is generated by nuclear reactors
  • Gravity – produced by planets and gravity generators. Spherical gravity generator also available.
  • Rotors – create rotating objects
  • Advanced rotors – able to function as a conveyor system
  • Refinery - process harvested ore to ingots
  • Assembler - manufacture components from ingots
  • Oxygen - take off character's helmet, generate oxygen out of ice by using the oxygen generator

  • Weapons - automatic rifle, small and large explosive warheads, small ship gatling gun, small ship missile launcher
  • Large weapons - missile launcher (for large ships)
  • Jump drive – a traveling mechanism that allows players to travel big distances in a short period of time
  • Solar panels - produce energy depending on the amount of light that they catch from the sun
  • World management – generate new worlds, “save as” to multiple copies, auto-save every 5 minutes (can be turned on/off), edit world settings
  • 32-bit & 64-bit - 64-bit version expands the amount of objects, ships and asteroids (almost unlimited)
  • Steam Workshop - Share your creations with the Community (upload and download worlds)
  • Modding - world files, shaders, textures, 3D models
  • Source code access – modders can get complete access to the game’s source code that can be found on Github ( This offers the opportunity for more and better modified content.

  • Conveyor, Collector, Connector (IMPORTANT: this is a first work-in-progress version and a realistic version will be added later) - Conveyors move items from inventory to inventory. Collectors can collect small objects (ore, ingots, components, tools) into inventory. Connectors can throw items from inventory to space (in future update could be used to connect two ships/stations and transfer items)
  • Artificial mass – can be used to add gravity-affected mass to ships, useful in machine ships or cars
  • Wheels - use them with rotors and artificial mass to build vehicles
  • Automated turrets – gatling, missile and interior. Turrets are used mostly as defense mechanism rather than shooting other players. They aim on decoys (automatically by default), meteorites, missiles or all moving objects (eg. small/large ships) - targeting can be changed in the control panel

I love this game and hate to give it a negative review but the main problem with this game is the fact that it is laggy af, the devs need to take a seriously close look into optimizing this game for performance. I have a more than decent computer but whenever I try to build, or paste on object that is remotely large (especially on a planet) the game just craps out and pushes my computer to the max. Ive got a 5th gen i5 running at 3.5GHz and 8 gb ripjaws X running at 1866 all the while being overclocked and I tried to paste an object on a planet that is 11,600 blocks big and it caused my cpu to run at 70% and my RAM to run at 99%

I went through some of the most recent reviews and am confused as to how these people are having all these issues with the game, I have owned the game for quite some time now and A group of friends and I touch back on it every few weeks, and each time we play, we have an absolutely, regret free time. This game has grown quite well, and it has never crashed on me or any of the guys I play with. Without a doubt there are some slight bugs here and there but they are few and far in bewteen. I was very excited to see planets added, and even more interested to find that it's a real challenge to establish a base on them. So we've decided to establish a space station, and move to a planet surface once better equipped.

Back on track here, this game is fantastic, and I have no clue where these bad reviews are coming from. I'm not saying these reviews don't have any facts in them, they do, but the issues are over exaggurated and the game is getting undeserved negative feedback out of what I can only see as frustration and spite. Multiplayer is not perfect by any means, most PUBLIC servers are poorly maintained by the owners and if they haven't been restarted regularly, they run like pure garbage, but this issue hasn't been found when playing in a privately hosted game, with yet again me and my few friends. I believe this game has a genuine space survival feel, one that isn't based around big ships and gun battles (which can definitely happen.) but it also has a strong and well executed focus on establishing your station, desperately searching for that one large deposit of raw material that will assure you and your crew survive long enough to start becoming self sufficient, and captures a real satisfying essence of triumph when you finally manage to build a somewhat complex system that allows you to process and combine materials, just so you can get your oxygen system up, all while keeping an eye out for Space Pirates from a small platform built into an asteroid in the vast heart of dead space.

This game is far beyond most games I have played, and I don't see mysl putting it down for a long time. It's definitely a game that belongs in everyones library.

This game was honestly a huge waste of money for me. It seemed quite promising and looked like a game I'd really enjoy.

After waiting three hours for it to install, I tried to play, and it was absolutely horrible. The graphics were gorgeous, but it was murdering my computer.

I turned down the graphics to the lowest setting, including the resolution, and although it was better, it was incredibly laggy.

This game is for people with beast computers. My computer is no more than a year or two old, and 95% of other games run quite smoothly with high graphics, so unless you have a stronger computer, I wouldn't waste your time or money on this game.

The concept of the game is amazing to be certain. However, the simple fact that I cannot even modify the controls is the most evident and most frustrating flaw. And when I try my xbox 360 controller, all I see to be able to do is move around, crouch, You know, the basic stuff.

I NEVER play games using the WASD keys. I find this to be the worst possible thing I can do when playing a game, I just cannot find myself to extend my left hand to play the game in that manner. I am sure a lot of people do not mind, but I cannot. It is just something that I find myself unable to do. I use the arrow keys to play any games requiring movement, so any game forcing me to use THEIR controls is a death warrant for the game itself. I was so looking forward looking to playing it, but not anympre unfortunately.

This game was a revolutionary concept back in 2014, and even now it is a pioneering project in the game industry, with full voxel based sandbox system in space with high detail graphics, planets, asterodis, mining, industry building, mechanic systems etc.
Unfortunately it became too big for the developers to finish as a quality game, and the underlying multiplayer concept is not working, it is too late to move to a professional netcode like raknet. This implies, that the concept of faction based, persistent, multiplayer game with lots of players (30+) will never be realised, which makes the game a pointless, unfinished sandbox. It can be considered as an abandonware, stuck in early access, with constant pretense as being fixed, while underlying fundamnetal problems never get fixed.

I never write reviews but I feel like KSH has lost their way again and are gonna drive this almost perfect game concept into the ground like they did to Miner Wars. It's a shame that after over 1500 hours in game, I have to shelf my favorite game due to bugs. The devs seem totally clueless as to how to fix the game too as every patch makes it worse and less playable. I've built bases, ships of all sizes, mechs, wheeled vehicles, satellite arrays etc, etc but none of it ever gets used cuz there is nothing to really do in the game. The "pirates" are a joke and the cyber hounds was Keen's way of trolling us for all the harsh criticism, I guess. I really miss the days when I could actually do things with my creations. Now mp is broken af and sp is a glitchy mess. Some optimization is noticeable but after almost three years of development the game looks further from completion than ever. Kudos to the dude that made the Trump ship with the caption "make space engineers great again" lmao...

Keeping this short. Space Engineers has a lot of promise. First however, it needs a lot of fixing. Server side I am aware of a nominally fixed memory leak caused by voxel updates (we think, hard to be sure). Not ACTUALLY fixed, despite patch notes: our server admin has tested this thoroughly.

Client side... I don't know where to begin. Sometimes my oxygen won't replenish, or my energy, when sitting in a pod with both supplied. Sometimes objects literally destroy themselves while I build them. Just now I lost almost two hours of solid work because things I build don't always default to BELONGING TO ME.

My advice is pretty simple. Wait until the devs iron out most of these things before giving them money for the project. Currently it is frustratingly prone to glitchy behavior, and while the game is playable you will see tons of things go wrong.

Tl;dr, Dark Souls 3 is more rewarding and less frustrating than this. Infer what you will from that.

Space Engineers is a very promising, inspiring and creative game. If you like playing alone in an empty universe, then you must definitely try this game. You won't regret it. It is one of the best single-player sandbox games I have ever played.

Everything is great until you try the multiplayer.
Extremely unstable, insanely laggy, frustratingly buggy.

No, it's not my internet connection (I have a very fast connection) and no, it's not my pc (I have a very high end pc).
It's just that the game is severely unoptimized. Whenever I join an online server, the game switches to s**t mode.

There are so many things not working in multiplayer that I can't possibly list them here, some of which are:

- Lag gets so extreme that you must wait for 30 seconds for even the most simple action
- Game freezes for 10 - 20 seconds for no apparent reason
- Player jumping all over the place, without any chance of controlling it
- Lag stuttering gets so intense that can give you a seizure
- On planets, player suddenly starts sinking into the ground, free falling to the center of the planet and ultimately dying
- Sudden death for completely inexplicable reasons
- Parked vehicles explode for no reason
- Stationed ships explode for no reason
- Drills and rotors explode for no reason
- Merge blocks explode for no reason
- Parked vehicles jumping all over the place for no reason
- Stationed ships jumping all over the place for no reason

You get the idea.

Overall, great for single-player, unplayable in multiplayer.
Yes, it is in early access but there are serious bugs that remain unsolved for 2 years and I don't think they will be ever solved.

Looks like this game suffers from the eternal-early-access syndrome, which is very common these days.

I miss the times where servers weren't speed capped at 50 m/s.

The times where you could actually move around normally without your character taking off into the sky when you move your mouse around with high sensitivity..

Something went wrong, really, really wrong. I don't know how or what it has been caused by but damn, do I miss the old game.. It makes me cry deep inside of me whenever I try to play on a server, it's like trying to get into something again but then it just scrubs you in the face with a metal brush.

And the times where multiplayer.. ughh nevermind, I bet most of you guys weren't playing the game from the start, so you don't know how I feel like about Space Engineers right now, the optimizations destroy the game rather than make it better, I remember a few patches back multiplayer was actually stable, but now it's A LOT worse.

New ships sounds don't really fit in, and they're skimmed off Elite: Dangerous, doesn't really feel as fast as it sounds like with only 50 m/s speed caps on the servers..

Only get this game if it's on ULTRA discount, unless you don't care about multiplayer.

Singleplayer runs pretty well, multiplayer is hell and WILL make you MAD many, many times.

Graphics are very nice, it's just the optimization part, playing on dedicated servers makes you rather want to walk on a contraband in real life than watch it happen in-game.

Short "review": Wait a year and see if this game is (still) in active developement. In it's current state it's more of a tech demo with a lot of performance issues. But it can be a great game in the future for sandbox and survival game lovers.

Good things
+ Looks good.
+ Fun to design and build ships, station and cars.
+ Cool with Star Systems, especially in Survival mode.
+ Got battle mechanics for those interested (can be turned off).
+ Pretty good damage and physics modeling - stations, ground and vehicles can break in a neat way.
+ It's like Minecraft with mods with better graphics but a more shallow tech tree (you can get the coolest stuff in a matter of hours in survival).
+ Lots of potential, can be a really great game.
+ Strong modding community, you can find a lot of good mods in the Steam Workshop.
+ Lot's of options on how to play the game. For example, do you want to start on the moon? Or in the outer space with only a crappy ship?

The not so good things
- Crashes, freezing your computer. According to the devs they have problem with AMD beta GPU drivers, AND Nvidia drivers. So what should we use? An old Matrox GPU? Anyways, sometimes you can play for 2h without a complete freeze, sometimes you can play 20 minutes, sometimes you get away with "only" restarting the game. But be prepared to reboot your computer. I have tried different drivers and settings, and the game crash (most often also freezing the computer) sooner or later. So saving and fully restarting the game every 45 minutes is a work around.
- Performance - This game is pretty taxing on your computer and the game has a sluggish feeling to it (even with 120 FPS).
And when fun stuff are happening (like destruction of ships/ground) it will get pretty nasty on the frame rate and general flow/speed (often called simulation speed in this game). So if you want to build a massive space station or planet base, be prepared for a single digit FPS and/or playing in slow motion.
- Save game corruption. You start up a new game in Survival, you decide to start on "Earth" in a Star System with Mars, the Moon and a Alien planet. After let's say 12h when you want to explore the star system you notice that the other planets are gone. You verify this with a save game editor. The moon is gone, Mars is gone, it's only "Earth" left. So save games can be corrupted (happened to me at least twice now). You can manually edit new planets in, but that's not the same and they will probably dissapear too.
- Progression: If you want the game for a strong Survival experience like in Minecraft (with mods), forget it - you wont find it here. There is no real progression other than mining, no tech tree, nothing to discover since all resources can be found everywhere (besides platinum that can't be found on "Earth"). This means that there is practically no reason to explore or play this like an adventure, you have everything you need where you start (or at least in 1-2h of play time).
- Developement cycle. At this rate I wonder if the game ever will be finished. There are weekly updates that bring new cool stuff. I would prefer if they focused on performance and stability before adding all the "fun" stuff. I know it's fun to add graphical updates and stuff like that. And bug fixing is a boring job. But sooner or later you (the devs) have to do the boring stuff too.

So, yeah. This game is in early access, developed by a small studio in a slow pace. It got huge potential and besides save game corruption and all the crashes I had fun with it. You should probably wait for your own sake, or get it now on a sale and play it when (or if) it ever get completed. Thumbs down for now but I will be back and hopefully be able to recommend this game.

Been putting this off for a while now, but due to recent spates of negative reviews i think it would be a good idea to make one, if only to make people more aware.

First off before the actual review i will write a warning to newer players.

This game is unfinished, do not judge it based on its current bugs as they are being fixed.

People who claim that development is taking too long need to realize that this was being developed by a very small dev team for quite some time until relatively recently (and a good portion of the current dev team is fairly new to game development), that they are working on two games at once (medieval engineers), and that they used better part of a year developing planets at the demands of the community (which a few members of the long term community think was a mistake. That is open to speculation). In other words, cut them some slack.

This game is EXTREMELY GPU and RAM intensive, i do not suggest running it with less than 8gbs, (16 recommended). Also bear in mind that some planets will refuse to load on low end GPUs and that others will run badly. For example you will run Mars at 30 odd fps on a GTX 750ti, 50-60 on a 980. Earth and the alien planet will run at 50-60 fps on a GTX 980ti (basically a titan x with less vram). I also hear that AMD cards and CPUs run worse than their Intel and Nvidia counterparts, though this is inconsitant.

As such i STRONGLY suggest you stay away from planets if you have a weaker GPU, i can manage 40fps on intel integrated graphics in space.

Multiplayer is currently broken, though new netcode is on the way and indications are that it is nearly complete. Stay away from dedicated servers until it drops, private games with 2-6 people run perfectly fine for the most part, though i do not recommend using pistons and rotors, they will invoke to wrath of Clang (the patron god of Space engineers and utter ruin).

That just about covers it for the warning, i will add more as i either remember things or otherwise find out more.


Now, for the actual review.

Space engineers is a semi realistic sci-fact voxel based building and exploration game (emphasis on the building part).
In this game you will build, mine and fight pirates (single player) and other players (multiplayer) in the hope of creating massive battleships to oppress the peasants, and defend what you own.

You can build basically any ship from movies, other games and TV series, or something original (but mostly you will end up building flying bricks due to your lack of aesthetic skill), the only limits are your imagination, and your computer.

Mining for resources is actually very fun in this game due to deformable terrain.

The fighting part could use a little work, but it does the job fine for the moment.

The exploration element is similar (if not somewhat superior) to that found in Elite: Dangerous, difference being the main reasons are to find a nice looking place for a base, look for resources, or if you have both, look for the community made ships that are placed extremely infrequently across the galaxy. Rather than just to have your name on a planet, though you can do that too if you really want.

The UI is, to be honest a little daunting at first, but it does the job.

The graphics are some of the best in the genre, and the models and effects are currantly being improved.

The music is decent (love the title screen song), but after a while you get a little tired of it.

The modding community is absolutely fantastic, on par if not better than the Skyrim one.

Infact the community in general is superb for the most part. Probably the best i have found yet.

The game is updated every week on thursday, and hotfixes released as soon as they are finished.

Youtubers for this game in general are great, i suggest VideoSage, XP gamers and W4stedspace.

That about covers it for the review.

TL;DR To me this game is fantastic and has the potential to be even better, and it looks like the devs are going to deliver.


Edit: Before putting a dislike in, make a comment so I know what you disagree on and how i can help fix it.

Not playable in it's current state. Devs need to reconsider the number of features and the overall method of networking and game functionality. It might be decent in a year or so, but we said this a year or so ago.

This game... I hope someday I can change this review to positive but honestly its been
years now and perhaps there have been a few optimizations but it is /still/ a bloody

Let me start by saying I recently re-downloaded this game, after giving up on it because
rather than optimize the game KSH just decided to raise the minimum system requirements
and I did not meet them. Prior to this I was eagerly awaiting the upcoming optimization,
planets, and new multiplayer back end update. All while suffering through the terribly low
fps and sim speed.

I was really enjoying myself on one of the preset earth-like worlds untill it got so slow that
it became a pain to even play(can we say memory leaks boys and girls? :D)

I've now uninstalled it and given up on it a second time.

I have heard KSH and their legion of fans preach "Premature optimization is the root of
all evil." as an excuse for KSH to not optimize their code untill beta. Well let me just
remind them that the /full/ quote is actually:

We should forget about small efficiencies, say about 97% of the time; premature optimization
is the root of all evil

~Donald Knuth

This was born in a time when we still were working with asm. Small efficiencies here literally
meant techniques that would have obfusticated the code base or making various,
per-cpu-model optimizations for a fractional speed boost. This does not mean make stupid
and wasteful choices while coding. This does not mean ignore plainly obvious bottlenecks in
code (I am certain there must be a few with how bloody slow this game runs). This does not
mean raise the minimum system requirements instead of optimizing the game.

It means write code intelligently, which is really not that hard to do if you are capable of
writing even basic programs (think basic utilities or really simple GUI without an IDE backing
you), but don't go nuts on refactoring or writing semi-obfusticated code just to reduce
processing a small amount. It means attach a profiler, determine where the real hogs are,
and address them instead.

I acknowledge that beta is a time of bug fixing and optimization. But that is precisely the
time for optimization of the little things, which is exactly what Knuth was referencing.
Fixing the bugs and optimizing the systems is something that should be done the /entire/

As I said, I have nothing but a few minor issues with the actual game itself (cyberdogs are
one of these issues for being so out of place and immersion breaking), but the VRage
engine is a trashy mess currently and ruins the game for me and several others I know.
I /really/ hope that I can actually run this game some day!

Thanks to whomever reads this, and best of luck to the devs :)

This game is very fun when it's working as intended, but i can't recommend it for people who want to play it with their friends, which was the main draw for me. The game seems to be a much less bug-ridden experience if you play solo and perhaps in a creative mode, but networked and survival gameplay is very much unpolished.

I've owned this game for years now and i've played it at multiple stages during it's development, which makes me feel like i have a decent grasp on it's issues with it's rate of development and bugfixing, which motivated me to write this review.

I had a lot of fun with this game. I've played it for near 100 hours. After KSP it's probably the best space sandbox game.
But despite all of it's potential i can't really recommend the game, especially as a person who likes multiplayer and playing with friends.

I've always thought that this game was great, but after having it for years i'm not seeing much improvement in terms of bugfixing and networking optimization.
If you want to buy this game, even despite all the bugs, in hopes that the developers will fix it.. I'm saying, don't do it. There is no guarantee that they'll fix anything, since they haven't really fixed any of the core networking issues since i first played the game. Everything is still jumpy, permanently desyncing, crahsing, etc.

The game is ridden with bugs that can break your server unless you clean it up occasionally.
It's also full of bugs that have you or your buddies constantly restarting the game.
Most of the game's issues are networking-related, for example clients not receiving the same information, even at <100 ping, which spirals out of control for some reason, ending at a point where clients may not see interactions of some objects at all, or they see everything 10km away from where it really is. These are really common occurences.
The conveyor system is full of bugs as well, sometimes pulling items in and out of inventories where items shouldn't even be allowed to flow due to the system not being in a loop, just a one way linear set of sorters, cargo boxes and assemblers.

Even though the maximum speed in the game is limited to a grueling 100m/s, supposedly in order to prevent the physics from breaking, it still constantly breaks, while making travel to other planets a journey that takes HOURS unless you mine for just as long of a time for resources to make and use a jumpdrive.

Starting scenarios are kind of a mess as well, there is no option to just start in a star system with asteroids and limited resources, essentially allowing you to play a survival mode where you can't spawn in new ships. There are some scenarios but they may not include some other generated features of the game. So you either modify server settings on the fly, or tweak your world with the editor in order to have a non-creative, survival experience with all the generated feautres (planets/moons/asteroids) of the game.
If you are completely new to the game you may miss out on these features entirely if you just start one of the scenarios that seem good.

I have the most stable computer i've ever had, reaching 10 weeks of uptimes regularily while playing games and using various heavy applicatios.
I don't think any game has ever crashed my system consistently since i've built my rig 2-3 years ago, yet space engineers manages to do it 2 times in an hour.

So, in closing... People who have played DayZ can understand a situation like this, where the game can be SO FUN yet so RIDDLED with bugs even after years of development, which is what makes this game really hard to recommend, because i DO want to play games with friends.
The DayZ developers worked with a proprietary engine that is very much known to be bug-ridden.
I'm not sure what the excuse of Keen Software House is, as they've been working this engine engine from the ground up, starting with their previous games.
Now they're also working on a game called medieval engineers...?

Have you ever wanted to play a game that had more bugs then a closed alpha? Have you ever wanted to claw out the eyes of everyone around you? Then look no further and welcome to "Space Engineers" where every moment your alive is another moment the chamber just went *click*. You are not mistaken I just compared this game to that of playing Russian roulette but instead of bullets it is bugs. Bugs with; a door, ship walling, placing a simple tire, a body not dropping its items on death, multiplayer net code, solid massive space objects not loading it as you fly into what you thought was open space only to die, and let’s not forget trees that are made of the same metal as the god Thors hammer. Did I mention you can pay money to see these bugs now? It is not even a closed alpha! So join the eyeless empire of those who have lost their soul, money, and humor to this hell gate of a game.

This game is awesome, although, am I able to play it is the bigger statment/question. Answer: NO!!!!!!!!!!
I have tried to contact the developers to improve the rendering of this game or at the least, offer better graphics options/rendering options. My computer used to be capable of processing this game, but after they came out with the planet update, my computer can't even render a small space station! I have also noticed that there was shading/shadows and pure darkness when enclosed in walls. I have attempted to fiddle with the settings to make it the lowest graphics/video settings avalible, I still experienced problems. Even though I am using a near to death computer now, my computer was capable to operating/running Space Engineers smoothly, but now, it does not!

Ok, i have been playing this game for a while now and i think its time to write a review.

+ great potential
+ lots of things to do
+ SP
+ Great non-toxic community
+ Capital ship battles with my friends
+ update videos, dancing dusan(music video coming soon maybe?).
+ Community plays a huge part in the design of the game.

- Bugs, lots of them
- MP sucks, (netcode improvements are coming tho.)
- optimization (working on it tho)
- Crashes
- rotors, pistons and all things CLANG.

In general i would recommend this game to anyone who has creativity and likes Space. The community is great and the devs bring out lots of teasers and information about development, its even possible to chat with some of the devs on xocliw's (community manager) stream or on discord.

The idea and gameplay* is wonderful and there are wide options for base and ship building. Planets and space are beautifully done and you really get a sense of freedom when you build a ship and launch off the planet. Finding resources and mining is fun (for example with self-made mining ship) and PVP is possible.


Alpha/early access or not, compared to the time it's been developed the multiplayer especially is broken with bugs. Dedicated servers are in trouble with the messy code causing delays all the time and major glitches keep happening all around. Simulation speed suffers immensely for relatively little disturbance (for example someone using too many drills at once). Bugs are currently inch short from breaking the multiplayer game.

Single player is better but still glitchy and demands a lot from your machine compared to what it should.

If you like the genre it still can be worth it to get this game but be prepared for trouble with multiplayer. Game is updated every thursday and we can just hope these major bugs are being addressed effectively. Soon. At this point I personally cannot recommend.

Unoptimized garbage.

That's Space Engineers in two words. I'm on a pretty new rig with a decent graphics card, a fresh Windows install with up-to-date drivers, and this game barely even wants to start up properly, never mind actually play. The fact that the devs behind this godawful nightmare 1) started development on a new game (Medieval Engineers) before this one could even run properly; and 2) were totally on board with the paid mods fiasco that Valve tried to make standard, is a firm display of ethical integrity on par with the worst mainstream game publishers such as EA.

If this game is ever fixed, it'll totally be worth a purchase. But that will probably never happen.

This game was a revolutionary concept back in 2014, and even now it is a pioneering project in the game industry, with full voxel based sandbox system in space with high detail graphics, planets, asterodis, mining, industry building, mechanic systems etc.
Unfortunately it became too big for the developers to finish as a quality game, and the underlying multiplayer concept is not working, it is too late to move to a professional netcode like raknet. This implies, that the concept of faction based, persistent, multiplayer game with lots of players (30+) will never be realised, which makes the game a pointless, unfinished sandbox. It can be considered as an abandonware, stuck in early access, with constant pretense as being fixed, while underlying fundamnetal problems never get fixed.

Alright so due to a recent impulse of negative reviews I want to clear up a few things about SE.
ONE, it is in (Beta), and has one of the most active development base in all of steam and early access.
Also, the main features have been added, and optimization is the next step, the game has gotten SO MUCH BETTER since it
first came out, and people complain about the performance after the planetary release, this was a huge feature.
The game uses a lot of computing for mapping out and modifing a massive planet, so there is a pretty big load on your
PROCESSORS, this game doesn't need a badass GPU, it needs a pretty good CPU to run smoothly. The Network coding is being completely restructured, so obviously it is going to take awhile to be sufficent, but it WILL be better than it was before. All in all, this is a great creative game that is great for you if you have a good rig and love other creative survival games like Rust, Minecraft, DayZ, H1Z1, etc.

Devs are more interesting shoving in cute little knicknacks instead of focusing on the optimization.

I'm not running a potato here, but I'm getting major stuttering because Space Engineers is using 150 Megabytes of disk usage per second. That's absolutely unacceptable. It looks fun to play, but you can't play it unless if you have a high-end SSD because the devs are too busy counting the wads of cash they're generating from Space Engineers and Medieval Engineers (both unplayable messes)

Early access is here to allow developers to show a proof of concept, and if it's interesting enough the game will spike in sales and the money, suggestions, and bug reports will come rolling in, speeding up development. To Keen Software, this seems to mean "Work really hard at developing a game, then give up and half-assedly make a spinoff before completely puttering out."

Do not buy. Keen Software doesn't care anymore, they're going to add one or two cute little features every week to show some sign of life and then have their PR people sweep their forums and ban everybody who calls them out.

There should never be a game where you must have one hardware requirement to play in one area and a higher one to play in another. Find a way to make both play at equal rates or change the requirement to account for the higher demanding area/s. That's just lazy.

Just to elaborate on the previous statement, imagine playing the legend of zelda majora's mask without an expansion pack. The game lets you play for a while, but the second you enter a dungeon your fps drops to the single digits. Game makers should know that you set requirements for a game based on the worst case scenario, for example a planet 1000+ trees on the screen, instead of the best case, i.e. out in space with 30 floating rocks.
