Notably, wheels have been given some much needed attention as well as pistons and rotors. Standing and walking around on a fast moving ship should be more stable and you may also notice that you can finally use a piston as a moving platform. Before this update, you character would just slide off. Voxel performance has been increased by around 60% so you should see more gains in FPS on planets.
Lastly, we’ve released a Deluxe Edition of Space Engineers on Steam containing the official soundtrack, concept artwork and a first release of the game from 2013. If you already own the Space Engineers, the Deluxe Edition should appear with a lower price for you on the Steam Store ;)
