This is a first-person shooter in which players assume the role of a special agent who must prevent an alien invasion. Players use shotguns, pistols, machine guns, rocket launchers, and grenades to destroy robots, aliens, and enemy soldiers. Firefights are highlighted by realistic gunfire, explosions, and cries of pain; some enemies emit sprays of orange or purple liquid when shot and killed. One cutscene briefly depicts a female character in an outfit that exposes moderate amounts of cleavage; the dialogue contains a couple of suggestive comments (e.g., "Damn, Andromeda is a stone cold fox" and "Inner chambers? Sounds kinky."). The words "sh*t" and "bastard" can also be heard in the dialogue.
