 Once the final boss of "Luigi's Mansion" is defeated, the player is given a rating (A to H) during the end credits, based on the amount of treasure Luigi has found.After completing the game once, a second mode is offered, called the "Hidden Mansion".In the European version of this mode, the mansion appears as a reflection of the previous version, with bosses being made more difficult, ghosts and Portrait Ghosts being trickier to capture, and more ghosts being in some of the rooms.
