About the game
Deadnaut is a strategic RPG from Screwfly Studios, the follow-up to their cult hit Zafehouse: Diaries. Deadnauts — so named because they're unlikely to return — explore, investigate, and fight through the derelict ships of dead civilizations. Every mission is unique and no two locations are the same.
