In the desolate, rust-colored expanse of Mars, Corporal William Thompson, a man haunted by a controversial past, embarks on a new chapter with the formidable Sol Union Corp. Yet, his hopes for a quiet life are shattered when a sinister red mist sweeps through the facility, transforming personnel into monstrous, feral beings. As chaos erupts and the base descends into a horrific inferno, William finds himself battling not just for survival, but for answers to a terrifying, otherworldly invasion.

Joined by Dr. Taylor Hall, a scientist unraveling a corporate conspiracy and the chilling truth about these "daemonsters," William must navigate a labyrinth of mutated horrors and uncover the secrets of a missing scientist, a rogue doctor, and a prophecy of ancient evils. With humanity hanging in the balance, William's journey becomes a desperate race against time to confront the forces unleashed and ultimately, to define what it means to be human in the face of absolute Hell.
