Players assume the role of Travis, an anime-watching assassin who fights his way through the ranks to become the number-one assassin. Being an assassin means using a retractable katana blade (i.e., a laser sword); it means slicing, chopping, and dismembering human enemies to death in this highly-stylized (somewhat 'cartoony'), cell-shaded action game. The depictions of violence in the game are intense, yet somewhat exaggerated: men in black suits are sliced in-half as blood and money flow from their bodies; an assassin with a boombox does not recover after his lower torso has been chopped off—after blood shoots from his empty waist like a geyser; and two women (clad in bikinis) get suspended in mid-air, get caught between the flashing lights, lasers, and frenetic sword swipes of an assassins' duel—the women's heads slide across the floor once the men stop fighting. Cutscenes depict more dismemberment: assassins slicing each other into several pieces in slow-motion, enemies pulling their own heads off, characters displaying trophy-heads on silver platters. These over-the-top depictions of violence account for the Mature rating; they also account for the Intense Violence and Blood and Gore descriptors. The language is strong, too, as characters sometimes use the phrases 'f**king a*shole,' 'f**khead,' and 'You gotta be sh**tin' me!'
The game contains sexual overtones and partial nudity. Players can watch portions of an anime show called Bizarre Jelly; the opening credits depict a female character whose clothes suddenly disappear, revealing her bare buttocks (one-to-two seconds). Game dialogue contains sexual references, including the phrases 'dirty nympho,' 'the one that's throbbing,' and 'I feel like that pervy teacher in a porn.' Female assassins are depicted in low-cut tops, thongs, short schoolgirl uniforms, and fishnet bondage-style outfits; breasts and buttocks jiggle, and the camera often lingers (there are no equivalent physics applied to male body parts). A couple of cutscenes contain strong sexual innuendo: when characters enter a store, a surprised clerk struggles with his belt buckle and zips up his pants (e.g., 'I was just. Uh, doing inventory.'); a woman moves a katana blade in front of a man's groin, kneels down, and kisses it (the blade), causing the retractable laser to extend. The battery meter for Travis's sword is always represented by a cartoon-like penis icon in the upper-right corner of the screen: as battery power runs out, the icon starts to shrink—a sad face appears.
