Update 01.132 - New Ship Sounds, Minor HUD Tweaks

This week's update introduces many new sounds for ships and vehicles in the game. We're also implementing HUD improvements and providing better modding support for sounds. Sounds are now determined by the size of the ship and type of vehicle. Small ships, large ships, and wheeled vehicles now all have their own unique sounds, and there are also unique sounds for gyros, thrusters, and reactors.
Cockpit sounds also now differ based on player perspective - in first person, you'll hear a 2D sound, but from a distance you'll hear a 3D sound. Each ship category has its own set of sounds and individual settings (volume, pitch range, etc.) and modders can now create and modify these ship categories.
Finally, HUD improvements mean that they now scale properly for resolution and multiple monitors.

Update 01.131 - Improved HUD Markers & Voxel Optimizations

This week's update brings you much improved HUD markers which means less text-spam and clutter on your screen while playing. Also all the markers now render by depth order, fade in & out and group together according to the situation and player's orientation. We will keep improving this system in the future though and we welcome your feedback!
We also made significant voxel modification optimizations this week, so there should be less stuttering, lagging and freezing when changes to voxels are happening (e.g. mining and explosions). And last, but not least, our modding community on github continues with the improvements of the programmable block/ModAPI. Thanks again guys!

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

    - 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

Early Access Review

I play singleplayer only, so I have no experience with multiplayer. I am also very patient, so loading, lag spikes, etc. do not bother me, but might bother others. Updates weeksly, getting better all the time.

Simple Review

- Realistic (as a game can be with physics and the sort)
- Great destruction physics
- Fun to experiment
- The good kind of frustration
- Playable for hours
- Make a train that goes from planet to planet (Personal achievement :) )

- Buggy (But, hey, its early access, what do you expect?)
- Required a very good build (I have i5-4690k, gtx 960 and get about 40fps on PLANETS on medium settings and well over 60fps in OPEN SPACE)
- Big loading time for planets and large worlds with lots of ships (personally doesn't bother me, as there is no other loading once you get into the world)
- Not much else

Great game, if its on sale BUY IT, you wont regret it. Full price? BUY IT, you wont regret that either!

Early Access Review
Day 1. I'm on a tiny, abandoned and crude space station on the side of an asteroid. I have only couple hand tools, no ship, no material for building. Space is vast, I gotta find uranium, fast. This is very scary flying so far off the base with only my jetpack. ..Oh noo some time down the line I lost the signal for the base! I guess meteor storms destroyed it's beacon.. I have no idea where the base is anymore. Forever, lost in space... ✞

Day 2. I woke up in a clumsy landing pod, descending towards some unknown planet. I'm panicking and trying to figure out the controls, finally, I'm almost on the ground,steady now. Wait, what did this button do.. Oh no! Managed to flip the pod right in the last meters, it exploded.. ✞

Day 3. I managed to land my pod, yeah! I don't need my helmet, I can breathe. First steps outside. Hey Idid't know this planet had life, look at those beautiful dogs, what a big pack! Wait, what the, oh for the love of AAAAHHHHHH.. ✞

Day 4. Back to my asteroid station, life on a planet is too hard. Getting my first scouting ship done, with a tiny drill. I coudn't get my reactors working though. Finally, I figured out the uranium couldn't possibly move through the conveyor system to the reactor without any power. Duh! I ripped the side open and added some uranium directly to the reactor. While doing that I noticed that peeping sound I kept hearing, it was becoming more frequent, I don't think it's part of this song coming from the radio afterall. What is it.. AHHH I HAVE NO OXYGE... ✞

Day 5. Note to self, tossing a piece of rock out of the cockpit while flying full speed will effectively break your ship in half and fling you out. I disorientedly watched my ship parts disappear in mere seconds to the vastness of the space.. Not this again. I figured out how to use the GPS system though and found back to my base, as it was conveniently set to be the zero point.

Day 6. I mustered up enough courage to face those vile dogs and decided to try landing one more time. Once on the ground I immediately installed a turret on my landing pod. Ha Ha! Die you %#&* §¤#! Yeah! They aren't so tough after all. Now off to build a base, quickly! Ohhh hey what on earth happened to my jetpacks now, what do you mean NO FUEL?! I'm middle of flying full speeAAHHH... ✞

Day 7. My planet base is coming off nicely, finding ore though is painful. I have no uranium and I don't have lot of energy left. I gotta move my solar panels higher, but I gotta save my last bits of jetpack fuel for dog emergencies. After a lot of work I built two pylons surrounded by scaffolding, and installed a rotor on top of them with solar panels. I have no idea how to program them to follow sun, though.. eventually, I figured out the day length and just gave the rotor a rotating speed divided by day length. Wow, it works!

Day 8. I used last of my spare energy to power up a small car I built. I turned off everything on my base to keep power usage to minimum. The improved solar panels are still barely charging my batteries. I'm only keeping turrets online to protect the base. Ok off to find uranium! Wow this car speeds up really fast. Oops better avoid that tree, hey what the..! Great, now my car is flipped over in middle of nowhere, I gotta figure out how to turn it around, maybe if I built a piston on the side.. OH MY GOD WHERE DID ALL OF THESE DOGS COMEAHHHH.... ✞

Day 9. I spent a lot of time today fiddling around with my tire controls, the car is now more stable. Gotta still drive it carefully though so it wont flip over, but it's good enough. Ha Ha hey ramming those pesky dogs with it deals with them in no time! Take that! I couldn't get a turret to work on my car, but this is maybe even more satisfactory.

Day 10. I found uranium!! It was very deep in the ground, but I managed to dig a steep slope to it and get back up. Digging in the cramp tunnel is scary and disorienting, I often panick when I can't see the exit anymore and loose my sense of direction. Fair enough the dogs didn't figure out how to follow me down there, I guess they aren't as smart as I thought. Finally I got my refiner and assembler working steady with this uranium. And most importantly, fueling my jetpack is not a problem anymore. One spare tank of hydrogen lasts quite a bit, even in this environment. (I carry 5, just to be sure)

Day 11. I started building a massive drilling ship after watching a distant proadcast from another planet. This guy was telling how he made one, it was very inspiring. He said the scraps of the old landing pod that I already disassembled would be plenty to get it going. He was right. Though I've used lot of the parts already for other things, his design is too big. I will make my own, a bit smaller. May take longer, but atleast I will learn better how to do it.

Day 12. My green driller was coming off nicely (I named it Monster), but one of those damned dogs managed to appear from nowhere and hide where the turrets couldn't see it. Before I even realized it managed to chew through the pedestal where I was building my Monster! Karma is a b*tch though, the dog died right after the ship fell on it, ha ha.. Monster is now flipped sideways on the ground. Luckily it didn't break however, atta girl.

Day 13. I finished building Monster, been working whole day to figure out how to flip her heavy frame back the right way. Those small atmospheric thrusters are really weak! 6 of them are not enough to lift Monster even a bit from the ground. ..Ohh great, now I managed to just get her flipped all the way upside down, sheesh. This model has hardly any thrusters downward, I will have to figure out a new approach..

Day 14. I added several big thrusters on the back pointing up (or down, from this angle). Now if I just coordinate this right it might work. First, lifting the backside up from the ground, and add force to nose tilting, yeah it's working! Monster is now wabbling on it's front drills. Now, carefully adding power to the front thrusters to lift it juuust enough to keep it turning back on it's belly with those new thrusters.. Steady, come on big girl.. Wohooo I did it!!

Day 15. I disassembled those extra thrusters from Monster fast, almost panicking. While I was trying to flip her back I managed to get quite far from the base. I was very afraid of those dogs appearing again and destroying my Monster. I had to add one more big thruster pointing down to get her howering easier. Fortunately I got her flying and now Monster is docked safely on the base. It was quite stable to control too, I am happy. Now I am ready to take over this planet! And some day.. Maybe reach that beautiful outer space again ♥

Most. Addictive. Fascinating. Inspiring. Early Acces Game. Ever. 10/10

Early Access Review
If you...

- like or liked building spaceships from Legos (and then smashing them)...
- are o. k. with playing a yet unfinished early access game in alpha-stage...
- have a decent rig...

...give Space Engineers a try! (If you are patient/cautious, wait until it goes on sale.).

Space engineers is a block based building game, often described as minecraft in space, but with more realistic looks and physics. (Disclaimer: I have never played Minecraft because it is not in space.)

It has a creative mode, where you can comfortably just build spaceships (or bases, or vehicles) and a survival mode, where you need to mine and refine ore from asteroids or planets before you can expand beyond your starter-ship. In survival, you also need to generate energy and (unless you turn that option off) oxygen. Either way you get to build your own ship from hull to windows, doors, thrusters, gyros, antennas, refineries, cargo containers, fuel tanks, air vents, conveyors, batteries, missile launchers, landing gears (or wheels), cameras, sensors, timers, script blocks and more. Then you can fly your spaceship in an asteroid field, land on planets, set up bases, mine ores, fight pirates... Space Engineers is a sandbox game, so beyond not dying you have to set your own goals.

Of course you can save the ships you have built as blueprints and upload them to the workshop or download ships built by other players. There are some fantastic creations on the workshop. Actually, if you are interested in this game at all, I recommend you just take a quick look around the workshop to see what can currently be done in Space Engineers.

Space engineers is early access and still in alpha. The developers update the game every single thursday. That update will fix some things, add some things and, inevitably in this stage, break some things. Be sure to report bugs - that is what early access is for. The devs do a hotfix every friday, so that you can enjoy the game better over the weekend.

While the devs listen to the community - they added planets by popular demand - they have been too silent in the past. They are making an effort to improve, though.

Being alpha, the game is hardly optimzed yet, even though the devs work on that week by week, too. Older rigs may struggle with it. Performance in Singleplayer can be improved with the right settings and good judgement. Multiplayer however is currently being completely redone and perfomance varies from week to week.

Early Access Review
One of the best sandbox games I have ever played, too many good things to say about it...but I have to give it a thumbs down...

I really want to give this a thumbs up but I can't.

The most important POSITIVE aspects of the game:
-Active developers (it's been a few years and the developers haven't quit on us, and if anything they are now spending every mintue of their personal life trying to better the game and not give up on the community, an update every Thursday)
-Survival and creative are both amazing gameplay features
-Multiplayer multiplies the fun factor of this game
-No limit in replayability (build and survive however, and whatever you want)
-The visuals are stunning for an alpha game (especially planets)
-Gameplay is very easy but complex, there is a learning curve but it's worth it in the end

The most important NEGATIVE aspects:
-Optimizations (when it comes to having to use DX11, performance is not too stable, planets can drop your framerate to 5FPS
-Bugs. There are so many bugs that can break the game, like flying through a solid asteroid, mining into a planet, or just multiplayer bugs in general

So you're wondering why I don't recommend it. Well frankly there are WAY too many bugs (especially in multiplayer) and the optimizations are horrendous.

I know it's alpha and we expect those to be present but it got to the point where it is so bad that a lot of people don't play this. What really killed it is the release of planets. Yes, I love the planets, great idea and great execution but there are just too many bugs and terrible framertaes that keep me away from playing it.

Once the devs stop adding and start fixing, then I will come back. Just keep checking, every few weeks, up on the game and see if the game has improved. P.S. It's been five months, since the release of planets, and the optimizations are still poor and there are so many bugs that keep me away from playing this.

Early Access Review
This game is now completely unplayable in MP. It just gets worse and worse with every fix. I can not recommend this game anymore. I do not believe Keen has the staff to fix and make MP functional. If you want to play SP you may enjoy it. But forget MP.
