This is a first-person shooter in which players assume the role of Morgan Yu, a man aboard a space station overrun by aliens. Players complete mission-based objectives and use futuristic weapons (e.g., disruptor pistols, laser canons) and special abilities (e.g., kinetic blast, psychoshock) to kill enemy creatures and human survivors. Realistic gunfire, large explosions, and blood-splatter effects occur during combat. Some environments depict large blood stains and corpses amid pools of blood. A handful of sequences depict additional acts of violence: a character executed with a gunshot to the head; a man impaled by alien tentacles at close range. During the course of the game, players' character can consume alcohol, resulting in a drunkenness status (e.g., screen-blurring effect, stumbling). The word “sh*t” is heard in the dialogue.
