Once the game is completed, "Anna Mode" will be unlocked, offering the player the ability to play as Nina's younger sibling and rival, Anna Williams. Various outfits can be unlocked throughout the game, which include a bikini, cocktail dress, purple jumpsuit, black and silver stealth suit. Playing the game a second time causes LCD crates throughout the game to contain infinite supplies of certain weapons, such as infinite katana and infinite rail-gun. After completing the game twice, the wrestling costume as seen in the opening FMV is also unlocked. A third clear game file additionally unlocks "Tekken 2 Nina", which instead of an outfit is actually a different facial and bodily construction, exactly as she appears in the "Tekken" title, in low resolution.
