This is a fighting game in which players engage in one-on-one battles using human characters and biological weapons called GEARs. Players punch, kick, and use various weapons (e.g., swords, chain scythes, giant scalpels) to drain opponents' life meters. Characters can perform super attacks in which characters are attacked by fiery blasts, shot out of cannons, and electrocuted by lightning. Combat is accompanied by sword slashes, cries of pain, and large explosions. Cutscenes occasionally depict smears of blood on characters' bodies and faces; one sequence depicts a character lying in a pool of blood after being shot. The game includes some suggestive material: female characters wearing outfits that expose large amounts of cleavage; camera angles that focus on breasts/cleavage; dialogue that contains innuendo (e.g., “Those hips—uh, I mean, those lips—no, I mean, that face! Yeah the face” and “The gown that you wear, is difficult to pull off, in more than one way”). During the course of the game, a character is frequently depicted smoking a pipe during matches. The word “sh*t” can be heard in dialogue.
