I describe Abiotic Factor as "Half Life 1, survival mode". Visually it looks incredibly similar, there are references to it all over the place, and it's set in a similar kind of location (a secret underground bunker full of alien artifacts). It's functionally a survival crafting base building game where you go and scavenge materials, create workstations, fill your meters and survive - in an office full of escaped scary things. It had a very successful active early access period, and has a good looking roadmap for post-launch too. Looking forward to playing more of it.
