Zero Sievert is currently available exclusively for PC in early access and you can find it on Steam. While it's an extraction shooter, it comes with retro-style 2D graphics that make it rather unique, vast procedurally-generated maps, extensive weapon customization, and plenty of storytelling via many quests.
