The listing, Deadnaut [Steam Key] has ended.
Deadnaut is Screwfly Studios' second game and follow up to cult hit, Zafehouse: Diaries.
Deadnauts, so named because they’re unlikely to return, must explore, investigate and fight their way through the derelict ships of dead civilisations. Every mission is unique and no two locations are the same. Each ship contains mysterious enemies and hostile security systems. Manage your Deadnauts' skills, talents, relationships and flaws - and you might get them out alive.
