L'ESRB (Entertainment Software Rating Board), l'organisme de classement des jeux vidéo américain s'est fendu d'une description de Bulletstorm pour justifier son classement en « Mature ». On y apprend qu'on peut démembrer des gens en buvant de l'alcool et en insultant leur mère et en faisant des Skillshots intoxiqués faisant référence à des actes sexuels, des maladies vénériennes

Si vous comprenez l'anglais, la description qui suit est délicieuse et paradoxalement donne sacrément envie.

This is a first-person shooter in which players assume the role of a space pirate who must escape a planet populated by mutant cannibals. Players use futuristic machine guns, shotguns, magnum revolvers, assault rifles, and chain guns to perform over-the-top kills that dismember and decapitate foes. Injured enemies emit large sprays of blood that stain the ground and surrounding walls. Specialty kills (i.e., Skillshots) represent the most intense instances of violence: enemies can be dismembered with explosives; impaled on spikes; and drilled into walls, resulting in body parts breaking into pieces. During the course of the game, players can consume alcohol and kill enemies in order to receive an Intoxicated Skillshot; the screen turns blurry during these sequences. The dialogue contains numerous jokes and comments that reference sexual acts, venereal diseases, and having sex with one's mother (e.g., "Guess I know where the ol' gal got that limp."). The names of some Skillshots are infused with sexual innuendo (e.g., Gag Reflex, Rear Entry, Drilldo, Mile High Club); one Skillshot (i.e., Fire in the Hole) allows players to shoot at enemies' exposed buttocks. Language such as "f**k," "sh*t," "p*ssy," and "c*ck" can be heard in dialogue
