This is a third-person shooter in which players assume the role of a CIA agent, William Carter, who battles aliens in 1962. Players control Carter and his team through squad-based combat missions, exploring sites and killing aliens and human enemies. Characters use a variety of futuristic firearms, as well as pistols, rifles, machine guns, and explosives in combat. Cutscenes also contain instances of violence: characters shooting each other at close range; an alien getting shot, with pieces of its skull broken up into pieces. An interrogation sequence allows players to choose to use force or not: if selected, Carter punches and shoots the alien while demanding information. The words “f**k,”“sh*t,” and “c*nt” can be heard in the dialogue.
