Tifa Lockhart from Final Fantasy VII is one of the new characters in Dissida 012[duodecim]: Final Fantasy. A fellow Final Fantasy character welcomes Tifa with the following line "Zoom camera into Tifa’s cleavage," according to the ESRB.
The leaked joke is part of their description, which probably sounds more salacious than it really is. Dissidia 012[duodecim]: Final Fantasy is just a T-rated game.
This is an action game in which players compete in one-on-one battles with characters from the Final Fantasy universe. Players engage in hand-to-hand combat in 3D arenas and use axes, swords, boomerangs, and magic spells (e.g., energy balls, summoned creatures) to drain opponents’ life meters. Battles are highlighted by cries of pain, colorful explosions, and slow-motion sequences that zoom in on defeated characters. A handful of female characters wear revealing outfits that expose large amounts of cleavage; some of these characters’ breasts also jiggle during combat. Some in-game text in also contains suggestive material (e.g., "Here’s a better idea: ‘Zoom camera into Tifa’s cleavage!’"). Various portrait galleries depict partially nude female characters; the general shapes of their bodies are displayed instead of actual detail (i.e., no nipples or genitalia). The words "a*s," "damn," and "hell" appear in the dialogue.
