Casualties: Unknown is an unforgiving cave-exploration survival simulator. Your captors have tasked you with retrieving lost cargo on a foreign planet, explore its 5 layers and do your best to survive diverse hostile environments. You are just one of the thousands of test subjects sent to die.
Official system requirements
Casualties: Unknown isn't sold on Steam, so we don't have Steam-published specs to display. Our 2026 hardware recommendations above are based on real-world performance testing and similar-title comparison.
Can your PC run Casualties: Unknown?
Check the manufacturer's launcher (Battle.net, Riot Client, Epic, etc.) for specific requirements — most live-service titles run well on a modern entry-level gaming PC.
