Dark Matter casts the player as an Ensign aboard a derelict spaceship overrun by alien threats and deadly parasites. Its 2.5D side-scrolling format frames survival horror around moving through abandoned facilities, where the darkness and hostile presence make exploration part of the danger rather than a backdrop.
Combat emphasizes preparation and adaptation. Players scavenge parts and blueprints, gather scrap and alien resources, and craft tools or health packs. Four weapons can be customized with upgrades, while elemental ammunition can freeze, dissolve, or set enemies on fire. The game describes its enemies as intelligent and reactive, and its non-linear exploration lets players develop their own combat techniques as they encounter them.
Light is a defining part of the design: the store description says illumination and shadow are integral to gameplay, and that enemies react to players’ actions and tactics. Its deep-space setting, scavenging, weapon choices, and tactical encounters shape that individual play.
