Space Marine 2 is out, but if you're too broke to pick it up, then Roblox may have the solution for you.

The Space Simulator is a space exploration game, where you gather resources to power up your ship and explore the vast expanse of space.

Roblox is a platform where anyone can publish games, and some fan developers have used it to create epic tributes to the grim dark Warhammer 40,000 universe.
