This is a first-person shooter in which players assume the role of an American soldier (B.J. Blazkowicz) in an alternate universe where the Nazis won World War II. As players help B.J. and his comrades escape various situations, they use traditional and futuristic firearms (e.g., pistols, shotguns, laser blasters, grenade launchers) to kill enemy soldiers and larger mechanized units. Combat is frenetic, with realistic gunfire, explosions, screams of pain, and large blood-splatter effects. Some weapons allow players to blow off enemies' heads or cut off their limbs; cutscenes sometimes show decapitations and/or acts of disembowelment. One scene briefly depicts a clothed couple engaging in sexual activity (a character straddling another); moaning sounds can be heard before the couple appears on screen. A handful of scenes depict female characters with exposed breasts: a woman breastfeeding a baby; a woman's shirt getting torn off during a firefight. During the course of the game, a character is seen ingesting a hallucinogenic drug (e.g., sheet of acid, tab of LSD); both sequences involve instances of hallucination. The words “f**k,” “sh*t,” and “n*gger” appear in the dialogue.
