Volatiles turns Betrayal at House on the Hill-style tile-by-tile map building into a gory survival shooter

Volatiles is an action game from 11 Bit Studios and Team Instant Defeat in which you wake in a strange facility and are dunked into a sensory deprivation tank to fight monsters in your mind. Each roguelike run starts with a single tile; defeating a wave lets you level up, place another tile, expand the map, bolster your skills and summon a new wave of enemies. Game director Ian Dovhan says the map-building idea came from Dorfromantik, not Blue Prince.
