Co-op factory-building game Satisfactory is now available in Early Access on the Epic Store. It'll stop you a bit short of completing the full game for now—Coffee Stain will be making bug fixes and improvements before adding the later building tiers as it completes its early access roadmap.

You won't have to worry about losing progress, though, as saves should be compatible with each new version. I played a bit of an alpha version with Chris, and we had a good time setting up efficient (or extremely inefficient) production lines, though it felt like there was still a decent amount of work to be done on the game. A few annoying bugs caught us, and when we ran out of explicit goals, I lost interest in making more and more screws and metal sheets, so the fun right now feels very dependent on the built-in tasks, as opposed to building for the sake of it. The animations are really nice, though, and we had fun exploring (me surfing on top of Chris' truck while he attempted to run over local wildlife, mostly).
