VIOLENCE: Players use futuristic firearms to kill enemies in intense battles, with impacts registering as blood spurts and explosions. Using knives to kill enemies causes blood to gush out of their necks, meaning there is dwelling on infliction of injury. The game also includes a zombie mode in which zombies can be blown apart or decapitated resulting in large sprays of blood.
OTHER: There is strong language (f**k). Some banners that players can choose for their teams depict drugs and items related to drugs, and sexual images such as a topless woman with zombie hands covering her breasts and a pole dancer.
