This is a first-person shooter in which players compete in fast-paced run-and-gun gameplay while maneuvering within a combat area. Players use machine guns, shotguns, grenade launchers, lightning guns, and plasma rifles to shoot and kill opponents (e.g., humans, aliens, robots). Realistic gunfire, explosions, and cries of pain are heard throughout the frenetic combat. Some female characters can be outfitted in g-string bikinis and tight-fitting outfits. One female dominatrix character briefly cups her breast and rubs her buttocks when performing a taunt. The word "sh*t" can be heard during some matches.
