Co-op build 'em up Space Engineers (opens in new tab), one of the best space games on PC (opens in new tab), just received a major new update that overhauls the graphics and changes the way that surface vehicles work. A video for the update, above, shows that the game indeed looks better than ever, with lots of new particle effects and a freshly polished colour palette.
On the visual side, the changes really are substantial. You can read about them all in this blog post (opens in new tab), but in short there are new textures, lighting effects, an optional cinematic mode, eye adaptation to sunlight, more lighting contrast and camera shake. The update has been a year in the making.
Most of the audio changes, which you can also read about in the blog or in the full change log for the update (opens in new tab), tweak existing sounds to make them more impactful (you now hear a heavier sound when your character falls to the floor, for example), adds new sounds and changes the way the game prioritises sounds based on the distance of their origin from your character.
The changes aren't all on the presentation, though. Guns are more precise, players move faster, and gravity behaves more realistically. Some of the biggest changes have been made to surface vehicles (or "wheels", as the developers calls them). Players will now find that they're easier to handle, and you can hit a button to perform a suspension jump—handy if you get stuck on the environment.
Again, all the changes, including a long list of bug fixes, can be found here (opens in new tab).
