In the distant future, humanity has expanded its reach to Mars, establishing research facilities on the planet. The Union Aerospace Corporation (UAC) conducts experiments involving teleportation and genetic engineering. However, a catastrophic event occurs when scientists accidentally open a portal to Hell, unleashing hordes of demonic creatures that begin slaughtering everyone on the base. A lone marine, part of a rapid-response team sent to investigate, finds himself trapped in the facility. Armed with an array of powerful weapons, the marine must fight through waves of demonic forces, uncover the truth behind the UAC's experiments, and prevent the demons from reaching Earth. As the battle rages on, he faces off against increasingly powerful and horrific enemies, culminating in a climactic showdown with the ultimate evil threatening to consume everything.
