This is a first-person shooter, set in the modern day, in which players join an elite army squadron on missions to hunt down terrorists. Players navigate battlefields in the Middle East and Russia; use machine guns, sniper rifles, grenades, and missiles to kill enemy soldiers; and attempt to disable the launch of nuclear warheads aimed at the United States. Realistic gunfire, explosions, and cries of pain are heard during the frequent and fast-paced combat. Soldiers emit large puffs of blood when they are shot and killed; there is blood pooling around corpses in some levels. In one sequence, players' successful sniping attack results in an enemy's arm becoming dismembered. One of the more dramatic sequences involves a depiction of a prisoner of war who is tied to chair, then shot in the head by a teammate. Strong profanity (e.g., "f**k" and "sh*t") can be heard in the dialogue.
