Steam came in a Space Sandbox with a huge open world – Space Engineers 2

In early access, Steam was released by Space Engineers 2, an “absolute” cosmic sandbox with “endless opportunities for creativity and discoveries”. The novelty received 80% of the positive assessments, but the players write that it is now more likely to be a techno with a minimum of a technician.

The current version contains the creative mode where you can build your first space structures and evaluate the new engine and physics. The developers warn that this is just an alpha book and they will not count much on much.
