Unlike other Half-Life: Decay mods, this project is focused exclusively on single-player gameplay. Tasks that previously required two players can now be completed solo: running the scanner, activating turrets, operating valves and doors are all accessible without a partner.
Important! The maps in the game are edited versions of the original Gearbox maps. Since they were not designed with saving capability, saving may lead to unforeseen consequences. Please use saves at your own risk. Missions have an autosave feature that should work as intended.
