StarRupture is a first-person open world base-building game with advanced combat and tons of exploration. Play alone or in a group on this sublime and ever-changing planet, extract and manage resources, create your complex industrial system and fight off hordes of alien monsters.

20% off. It’s Satisfactory but with tower defense and the world catches on fire sometimes.

I don’t do early access but $16 is hard to refuse. It’s on my watch list for full release.
