Update 01.144 STABLE; Update 01.149 DEV - Bug Fixes and Improvements

This week’s update brings you more bugfixes and improvements, as well as a new animation when rotating blocks. This short animation should help players better see how blocks are being rotated.
Improvements this week focus mainly on rotors, pistons and wheels when flying in a ship. Other bugs fixed include trees being too strong, mirroring issues with the refinery, certain cases of ships sinking through voxel, and teleporting through walls by exiting cockpits.
Today's update to the stable branch contains most bug fixes from the past month. It also includes certain features, like the new building system and modding changes. However, it does not include recent features like the meteor improvements - for those, jump over to the dev branch to try them out.

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.

  • 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

  • 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

  • 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.

Dang you Direwolf20 and your Space Engineer Let’s Play series. I was looking for some new Minecraft news from you and wound up getting hooked on Space Engineer. There… got that out of my system; on to the review.

SE can be extremely addictive should you favor sandbox type games. Endless possibilities exist, even without any mods. Granted, the game doesn’t do much handholding for beginners, but a quick read on the SE Wiki or watching a few videos such as the aforementioned Let’s Play series will get the foggiest beginner on the right track. The mechanics are very simple once they are grokked. From there, it is just a matter of imagination.

SE is multi-player capable right out of the box. Host a private server on your office (*cough*) network for co-workers to enjoy or set up a dedicated server at a hosting company for access from anywhere in the world.

One has to squint a bit to see its physics emulation as real-world, but it is good enough for gameplay. Trust me, you will learn to respect its physics. Don’t learn the lesson the hard way and see hours of ship design crash into the side of a mountain or asteroid because of a missing engine in the proper direction – I should have turned the ship 180 degrees to use its rear thrusters to avoid the immovable object, instead I sat there in disbelief thinking my keyboard went wonky. Thank goodness for intermediate saves!

When everything works right, SE is a lot of fun; when everything doesn’t, it can be frustrating. Hey, the game is in early access and its developers are continuously making improvements. Yes, sometimes a new bug is introduced with another bug fix or new feature, but that is beta testing for you. If you want this game to work 100% of the time, please save yourself some frustration and wait till SE is officially released. Meanwhile, we will help them iron out the kinks.

Many excellent mods are available to add new blocks, better blocks, and other features. SE even includes the ability for in-game C# scripts to control and manage almost every controllable block. Don’t know programming or C#; no worries. There is a host of scripts available to use without creating one line of code; well, maybe modifying a couple of definitions, but that is all. Just be wary of noob coders and mod authors. Read all the comments first, especially if a mod’s description starts with “The is my first C# program” or “I hacked this together, use at your own risk”.

I’m currently putting SE’s multi-player server through its paces to evaluate its readiness to be included in our gaming network. Multi-player is definitely a lot “rougher” than single-player, but the pros of cooperative play – or red vs. blue type scenarios – greatly outweigh multi-players cons.

However, this game is in early access. Yes, it was mentioned already, but bears repeating. If you are impatient or feel great pains when things break, please… please… come back when all the rough edges have been fixed and SE’s production release comes out.

Fun game so far. Could do with some bug-fixing here and there, but I'm hoping the recent showing of No Man's Sky will light a fire under the developers asses. Definitely worth picking up when it's on sale, I wouldn't pay full-price for a game in alpha, though. Especially one as long as this one has been in alpha.

If you said yes to any of these questions, this game may be for you, but I will also mention what this game ISN'T below. (Additionally, if you are looking at this game's reviews and see lots of "not recommended" don't worry. They are like a Year Old. If they are talking about when planets were new, it was around a Year ago this time. The Devs do weekly updates and for the past 2 months or so there has been no new features except bug fixes.)
TLDR (I made a massive all of text too big for the character limit, stupid me, rambling on aout stuff): Barely Any NPCs, Obviously Scripted Meteors, Laggy with large Ships, Complex Landforms, and having anything in the graphics options on "high quality", Can take window apart without ruining glass but turns batteries into Scrap Metal, Rotors and Pistons as well as Landing Gears like to Malfunction and Explode, and the max speed of 107MPS is too slow.

I love this game! It has a building interface like that of minecraft, but includes the thrill of space travel and survival. It allows me to control how difficult the game is by manipulating the settings. The things you can do with the game are almost limitless with the availability of mods. If you get bored of fighting the A.I. in singleplayer, then you can test your survival skills online. All this being said, there is one problem; Waiting. However, I don't want to discourage anyone from getting this game. The waiting and lag is a huge problem for those who are only playing games for a few hours as opposed to the people who game at an intense level. It takes long to load even singleplayer worlds, and it might crash when it finally loads. The lag is immense, and I have not even tried online yet. But hey, it gives you time to do other things, like eat lunch while your game is loading. I guess this is why it is in alpha. If you have some patience and a love for survival games with limitless possibilities, then this game is for you. P.S. I have a pretty slow computer, so it is much better on gaming laptops and desktop computers.

Latest update completely broke the game for me, I spent ages building a ship on a planet, only for the game to say that its now a station? not a large ship? and subsequently 'unflyable' (although somehow able to defy gravity and float of its own accord) The physics and gameplay have gotten progressively worse as it has gone on, focus shifting away from enjoyable space exploration/creation and instead to some weird stupid minecraft survival clone mode, with annoying spiders, cyberhounds and drones spoiling your creations, the combat to repel them is still terrible and adds nothing to the experience.

I loved this game and sunk many hours in to it, but right now I'm finding it so irritating to try to play. It seems as if they have removed quite a few objects too, which is never good for a 'building' game.

PHENOMENAL!!! if you have any kind of critically thinking creative mindset, you should give this game a few hours. even with the hours i've logged, i'm still learning.

The Game has a remarkable player base, albeit small, they are innovative and never cease too bring find fun in the emptiness of space, and the vast fields of the planets.

Solo survival is great for learning how to play, but if you'r anything like me, you'll want to leap into pvp asap. I would not reccomend it. You rarely find other players due to the sheer size of space, (unless you have mastered building com arrays and scanning deep space for players.)

This game is endless fun for me, it only gets better the longer you play, and as an early access it can only go up!

Its exactly what you'd think it is. Space Survival/Building. Can be really fun, but you really do need a decent pc for this to run at a good fps. Overall, even though I run it at around 15 fps, its pretty fun.

This review is heartbreaking for me.

TLDR: Keen ruined this game.

In it's alpha prime, when it was still a space sandbox, PVP was amazing. A cluster of asteroids that pirates and miners fought for with creations of their own designs.. perfect.

Instead of optimizing that, they listened to whiners and pressure to do other things, and released planets. And started Medieval Engineers. And made exploding wolves.

Been waiting on Netcode, stability, and clang fixes for over a year now without playing. (most of my hours logged were pre-planet PVP and design.)

Consider that this review was written on 09/08/2016. This game may have changed meaningfully between then and now.

I've got a lot of hours down in this game. I've enjoyed it. Not anymore though.

The game does have merits.

- I've enjoyed survival mode a lot. It's fun to start with limited resources and scrounge up what you can to build and progress until you finally have the resources to build something impressive. It was very fun when I came across a derelict station to explore it and gradually rip it down for parts. But I played 300 hours of this game before that ever happened; it was the first and only time I came across one. They're apparently sparsely located, and, naturally, they're difficult to see in space.

- Planets can be an interesting challenge, to an extent. Wheels were added a long time before planets were, but they were basically redundant. There wasn't an advantage to making a wheeled vehicle in artifical gravity over a flying one, really.

- There are very many mods. If you don't like something about the game, there's a good chance it can be changed. Mods include upgrade modules for thrusters, different suits (models and different stats like hydrogen, carrying capacity), new planets, more encounters, homing missiles, skyboxes, probably any given armour block you would need..Keen have really made this game very modable.

- Programmable Blocks have allowed for many interesting possibilities. I've seen a script that draws a map of your ship and represents the damage as it takes it, radars, reports on inventory..It can be very interesting, if you know any C#.

- The armour damage is very nice. The best part of making a large ship is taking it into battle and wrecking it.

But it has more cons at this time than pros to my eyes.

- After playing enough survival to get on your feet with a stable supply of resources, what is the point? There is nothing to drive you but the goals you set yourself. There are enemy drones, but they don't seek you out so much; you have to come into their sensor radius first, then they'll come after you with drones. You can do a lot as far as building goes, but there isn't any reason to. In that sense it's more like a tech demo. The same for creative mode.

- If you've read much about Space Engineers you may have come across the name "Clang", a joke deity players made up to explain the very frequent physics bugs that afflict this game, derived from the noise they make. They didn't do this after only a little while; it's been broken all along. Many ships have been lost to splruging pistons, rotors and landing gears, the latter of which is to be fair better than it was. But it still very common with rotors or pistons in my experience to simply blow up your machine.

- Where's the engineering in Space Engineers? The only blocks that are really mechanical are Pistons and Rotors. These are both horrendously broken a lot of the time, and are actively avoided in ships and stations by most players because they have a tendency to blow up. So the only blocks that are designed to make elaborate, custom machinery instead of premade blocks are deathtraps, and in one of their livestreams (or possible their roadmap on Marek, the CEO's devblog) they basically said they have no plans to add any more blocks like those because of how much trouble they've had with pistons or rotors. At this time, if you want to build a walking mech or some other elaborate machine, you can probably forget it.

- There's actually not much depth to planets, it seems to me. You're relying more on solar power and batteries because Uranium the usual power source, is scarce, so you can't just throw thrusters at everything. However, once you have enough batteries, or find some uranium, you can do whatever you want more or less. Furthermore, my experience of tyres has been that they're more likely to flip you over than give you any stable vehicle; they have plenty of settings to modify to fix this, but you have to do so much fiddling to get a wheeled vehicle worth a damn. There's also no way of making a plane that flies like a plane; if you want to go up, you need thrusters.

- Reliance on mods. I believe that Keen have made their game so modable because they want many possibilities to exist in this game but don't want to spend the time and money doing it themselves. Look at the amount of things that are mods that should, in my opinion, be in the core game. For one, suits with different attributes. You can get a mod for a heavy suit that is slower but can carry more, or a fast one with little capacity, and so on. Those should be in the game itself. Or the Aerodynamic Wings mod that lets you make planes that can fly more like real planes, instead of the fake planes you would have to make in the base game that fly with downwards facing thrusters.

- Enemies. There are drones in space that aren't so bad. The drone Argentavis will occasionally appear and may head for something nearby. Itcan spawn other types of drone..some are designed to attack, others designed to look around and summon atack drones if it finds something. I've never tried capturing it myself, but I'm told it's a challenge. It's not so bad. But on the Earthlike Planet, you have Cyberhounds, packs of cyborg dogs that appear from nowhere, spawning near you, and attack. You can't outrun them. If they can't get to you, they will chomp at the nearest structure. Why do they even exist? In universe? Someone must be making them. But more importantly, they're not a challening enemy, they're a nuisance. Set up a moat (with no water, because water is actually solid ice) and you'll be fine. Or if you have the Magnesium, a auto-turret. Or if not, set up some grinders with sensors that turn on when enemies draw near, they'll walk right into it. Alien Planets have Sabiroids, spider-like creatures with basically the behaviour as Cyberhounds. Except they will happilly glitch-walk right over each other and if memory serves don't eat your work. Both of these types of enemy, I've seen, may well spawn inside your structures; they spawn within a certain radius of you, not taking into account your environment.

- Multiplayer is broken. They say they have been working on it for some time, and are fixing it. Most accounts I've heard suggest it's still dross. A person managing an SE server really must put in effort to get it to not perform like crap. The most popular tool for this is a third party on called SE Server Extender, if I remember rightly. I believe Keen were considering integrating it into the game .

- Don't expect to be able to detail your ships worth a damn. Large Ship Blocks are large, often stupidly; a Catwalk is a very thin bit of metal, but it still takes up the whole space, meaning I can't have a walkway with a light above it in a 1 block space. Simple things like that can't be done, so if you want detail it ends up bloating your entire ship. There is a mod to give small ships all large ship blocks, which can give you great results, but the large small ship may be poor for performance.


- Tonnes of mods
- In-game programming can be good.
- Deformable armour is great.
- Pretty large planets. Several types (Earthlike, Alien, Martian, etc)
- Single Player is fine enough so long as you set your own goals.
- There's basically no engineering in Space Engineers.
- Rotors and Pistons will break your work.
- Large Ships have to be very big to have much detail.
- Things that should be game mechanics are left to modders (which I believe is Keen's deliberate laziness.)
- Multiplayer is broken.
- Enemies are very dumb, and don't make sense in-universe (cyborg hounds, who is making them?)
- Planet performance varies wildly depending on your computer and has not much depth.
- The devs are also friends with several of the more prominent YouTubers who play this game, which I think is inappropriate.

I suggest not to buy.

I desperately wanted to enjoy this game. I did everything I could to make the game as playable as possible. But in the end, this game is an unfixable wreck that Keen has left us with. Few new features are getting added, and we're left with a broken mess that is Space Engineers. For starters, this game is incredibly unfriendly to people who don't have a top of the line computer. Besides for how high the requirements to smoothly play this game are (I probably should have payed more attention to that before buying), the game also only goes as low as "normal" for graphics IIRC, and has very few graphics options. In addition, they stopped supporting the dx9 version which turns this from a game my computer can barely run to a game that makes me feel like I'm watching a slideshow.

The overall idea though is great, and I loved the idea of building fleets of drones to do stuff for you, a little bit of which I actually did before they dropped dx9 support, and even though I still have the dx9 version, I got tired of 15 FPS constantly so just stopped playing.

If Keen ever takes measures to reduce lag, then I might consider trying this again, but until then, I'm just going to have to thoroughly regret buying this game. If you do have a good enough computer, then I'd somewhat recommend this, but this game still has a whole array of other problems mentioned in other reviews.

If you dont have a good computer dont buy it. It is very laggy. The Devs need to optimise this game

This game has one of the more innovative and interesting construction mechanics i've seen, and has had an opportunity to do what tekkit and its ilk never could; It could have let engineers fight not just with combat skill but with their skill in engineering. The vast creations of players could have dueled where factories in Feed The Beast could have only refined the materials you threw into them. The joy is in the puzzle of maintaining the unwieldy system you yourself built.

But this game has none of that joy.

With rare exception, Engineering does not matter, only guns and armor matter.
With rare exception, piloting does not matter, only guns and armor matter.
With rare exception, being smart does not matter, only time spent working matters.

It is my firm belief that progress in a game should not be marked by time spent, but by mastery achieved. A grind is no substitute for gameplay.

(oh, also, Keen software somehow managed to one-up minecraft's wolves update, by making an update with EXPLODING CYBER WOLVES whose role in the game could have been filled in many different ways using any number of systems already in place. KSWH have, design wise, forgotten what they have.)

TL;DR: No.

Look...I wanted to make a long, detailed review, but I ranted so much into the review box that it was actually too long to post. Steam wouldn't let me.

The problems with Space Engineers aren't necessarily going to show their face at first. At its' core, the game is still the same one we got when it entered early access alpha 3 years ago. It's still fun to build ships and fly them around, fun to watch them crash into one another and splinter up and break and dent and all that jazz. If you have a computer capable of hosting a server with friends and they have computers capable of running the game, the multiplayer can also still be a ton of fun. And the game has a huge modding community, which is always a huge plus, and it can easily support itself feature-wise without it. Not to say it SHOULDN'T have one, of course, but it's a good thing when a mod-focused game doesn't actually need mods.


3 years ago I ran this game on a potato. It ran like a charm. I never had any issues with lag or any crashes or anything. When multiplayer was introduced, my friends joined me and we all played on potato-quality PCs. It's all we had at the time and you know what? The game ran perfectly. Nobody ever had an issue with it.
Somehow since then, the game has managed to turn into the most sluggish, buggy, awful piece of ♥♥♥♥ I have ever encountered. Period.

I can get 60 FPS in this game. Usually. Mind you, my computer ALSO has a brand new Nvidia GTX 1080 in it and a hex-core i7 processor with an absolutely huge overdose of ram at 64 gigs, which is used for video and music production - I never thought I'd see a game that actually needs ALL of it. And even then, the game will crash due to running out of memory and just dumping to desktop without warning. Sometimes, right when you load in. And dont you DARE alt-tab - that causes it instantly. Saying "Usually" also means that I have to turn things like anti-aliasing off entirely and, of course, not even think about playing on planets, which are one of the game's biggest features. Planets lag like ♥♥♥ and there is NO workaround for it outside of plain and simple horesepower. That's not a good thing at all.

The friends that used to play with me for the most part can't anymore. Without a godlike internet connection, the game will cause them to stutter around and die to literal nothing - they will just suddenly be dead without having a clue why. Turns out it's usually because they lagged into an asteroid or something and didn't see it coming. Of course, that's if they can even run the game. I have a friend who can get about 30 fps in space and, well, on planets? A healthy 4 at minimum settings despite surpassing minimum requirements for the game by a large margin. Slideshow quality graphics do NOT count as ABOVE MINIMUM SPECS. And seeing how the game used to run better at higher settings on ♥♥♥♥♥ier hardware, I'm entirely blaming the game for this one.

So performance is a hit. "Well," you say, "I have a god-machine that ran me down the price of a luxury vehicle and runs 400 servers across various games daily, I can run this, your PC is trash lmao". That won't save you from the constant array of glitches. The game does nothing but insert workarounds. Passenger seats were added because they can't be bothered to fix other players glitching out of a ship while it's in motion. Piston and rotor safety locks were added because they can't be bothered to fix them flying off and causing your whole ship to detonate spontaneously due to trying to TURN. The faction system doesn't work worth a damn since any time you build new blocks, they are by default neutral, meaning if you add blocks to a ship that belongs to your OWN faction, YOUR OWN SHIP WILL OPEN FIRE ON ITSELF TO REMOVE THE NEUTRAL HERESY YOU JUST INSTALLED. The oxygen system has had its pressurization system turned OFF by default now even on pre-existing worlds because it's too buggy to bother fixing, so LETS JUST MAKE IT SO IT DOESN'T EXIST ANYMORE.

There's your rant. Reduced size for you, Steam.

Oh and did I mention the game has been in alpha for 3 years and shows no signs of ever progressing past that stage? And every other game the company has EVER made has been abandoned, including Medieval Engineers?...right.

When I first got this game I thought it was amazing.
It changed a lot with planets and everything but poor physics and lack of optimization makes it unplayable.
It uses too much ram and cpu, after 3 years, this game still doesn't support multi-threading.
I recommend to get this game if you have a good computer.
This game won't do well on ordinary laptops with "okay" specs(except gaming laptops)
Seriously, it uses too much ram and cpu. Your graphics card won't do much.
Again, I highly recommned it if you have a decent computer but if not, please don't get this game you'll regret it.
