Update 01.102 - Performance & bug fixes, Character's jump corresponds to gravity strength

The performance issues related to thrusters, turrets, rotors, sensors and rendering have been fixed. We’ve also applied several other bug fixes such as game crashes caused by landing gears. We’ve also updated the wheels so they behave more realistically - this is the first iteration and more improvements will follow in the next updates. Additionally, the character’s jump is now reflected more realistically according to the gravity strength. Lastly, we would like to thank all of you for helping our team by reporting issues that you find in the game. It is really very important for us! Sometimes things might not go as expected and bigger issues might appear, but you should know that we are always doing our best to fix everything on time and provide the best gameplay experience possible.

Update 01.101 - Landing gear fix, Performance improvements, Small ship turrets

This week we added turrets for small ships. There are currently two types: gatling and missile. Additionally, we have applied several improvements that will optimize the performance of ship destruction and turrets, allow more moving ships in a server, and also stabilize constraints and collisions. We also added a pirate raiding carrier that will approach its nearest enemy and spawn light attack drones. Eventually it will leave on its own. But keep in mind, there is a large but well protected treasure hidden inside it! Moreover, we implemented more encounter ships from workshop creations. Thanks a lot to JD.Horx for his IMDC faction fleet! More additions will continue in the future. Last but not least, the exploding landing gear issue has been fixed! We are sorry that it took us so long, but we are happy that it’s finally solved and we hope that it won’t destroy your creations any more :)

Full list of new features and fixes:

EDIT 09/25/15:
Update 01.101.027
- fixed multiple crashes
- fixed warnings and animation of jump drive
- fixed turret definitions
- fixed jetpack power usage

EDIT 09/28/15:
Hey guys,
The last update introduced requested fixes such as performance improvements and exploding landing gear, but unfortunately it also introduced some new bugs for a number of players.
Due to the upcoming release of Planets the Space Engineers universe is undergoing lots of changes behind the scenes and some things may not work as expected.
We share the frustration with you and are very sorry for the issues that appeared after the last update and we are aware that the performance improvements didn't work for everyone.
These issues are our main priority and the team is working on fixes around the clock to make gameplay and building experience as smooth as possible for everyone.
Thank you for your patience and amazing support. Keep the comments flowing and report any issues you have in our forums here:

About This Game

Space Engineers is a sandbox game about engineering, construction and maintenance of space works. Players build space ships and space stations of various sizes and utilization (civil and military), pilot ships and perform asteroid mining.

Space Engineers utilizes a realistic volumetric-based physics engine: all objects can be assembled, disassembled, damaged and destroyed. The game comes with two game modes: creative and survival.

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

Early Access Review
How to play Space Engineers:

1. Buy game
2. Think tutorials are useless
3. Try jumping straight into a survival server
4. Either:
a) Suffocate to death after wandering around aimlessly in space having no clue what to do
b) Get shot to pieces by hostile ships (unmanned or manned)
c) Crash into an asteroid at 104 m/s after thinking braking is instant
5. Rage quit
6. Boot the game up after a while
7. Spend about and hour going through tutorials
8. Start up a solo creative server to build a small all-purpose ship
9. Marvel at your engineering prowess
10. Go to the workshop to publish your majestic ship
11. See infinitely better ships the size of small moons
12. Weep in failure

10/10 would die helplessly and make designs that look like the work of a preschooler again.

Early Access Review
Space Engineers is an Early Access game and have been for quite a while. It is in Early Access game with quite a bit of content and more is being added on constantly.

What is in the game?

This is an open sandbox game with lots to explore, it is not your typical sandbox game, it is a unique sandbox-space game. There is lots to do, you can build spaceships, explore outerspace, build space stations, have ship fights with friends in your almost fully destrutible enviroment.

Is this game worth the money?
  • Personally I think it is worth it, there is so much to do in this game, there is two game modes, Survival and Creative. Pretty self explanatory but Survival is where you are trying to gather your supplies and trying to survive and create your spacestation, but in creative you get to create your own spaceship or spacestation or whatever you want to make with all the tools at your fingertips.
  • Yes the game is a bit expensive 25$ at the moment, it did go up recently from 20$ if you dont want to spend that much then just wait for a sale when it will be much cheaper.
  • The game is fun but even more fun with some friends to mess around with.

  • Huge Workshop, there are over 150 thousand workshop submissions from Spacestations, Spaceships, and all kinds of machines.
  • Regular updates to the games, some great devolopers working on this game they update 1-2 times a month.
  • Great game there is so much to do, you can have huge space battles with friends, build an army of spaceships, have races in fast spaceships, build a deathstar.
  • There is a great high detailed tutorial that helps you figure out this game which can be pretty complicated at first.


  • Again this game is a bit expensive, 25$ is quite expensive for some people but it does go on sale and when it does you should get yourself a copy and maybe one for a friend.
  • The controls for flying ships are a bit hard but once you get used to them it becomes more enjoyable.
  • It does take a while to build stuff and can be challenging and frustrating when a friend or someone or even yourself destroys your creation in a matter of seconds

    My final thoughts and opinion of Space Engineers
    This game is still in Early Access and is one of the better sandbox games i have seen and played so far. There is 100s of hours of gameplay to offer and maybe even thousands. There is plenty of mods to try out and play. There isnt very many gamebreaking bugs (or none that i have found or heard of) but the developers are always updating and patching bugs. This is a great game for early access and i am excited to see what is to come later, i highly recommend this game to fans of sandbox games, and fans of building games.
