Once the game is completed, a new game plus mode is available called "EX game". It is different from the normal game in various aspects; the player has access to every item stored in the police station, the game begins with the final weapon and armor the player chose before ending the first game but returns to level one experience, and the bonus points (BP) given to the player at the end of the game are now available to use. The items, weapons, power-ups and enemies are more powerful, as are the enemies the player encounters. However, the biggest difference from the normal game is the addition of the Chrysler Building, a brand-new location with 77 floors (containing mostly randomized content), leading to a final boss battle with Aya's older sister, Maya.
