This is a third-person action game in which players assume the role of an engineer (Isaac Clarke) who must fight his way through hordes of aliens aboard a space station. Players use futuristic weapons (e.g., plasma guns, flamethrowers, electrified spikes) to kill a variety of mutated creatures—attacks generally result in cries of pain, dismemberment, and large spurts of blood. Some cutscenes depict close-up views of characters getting stabbed in the face by blades and needle instruments. Several environments depict mutilated bodies, as well as blood-splattered floors, walls, and ceilings. The words "f**k" and "sh*t" can be heard in the dialogue.
