Notes for Luigi’s Mansion 3 players.

Players should pay attention when playing Lu Yi's Haunted House. The scene where the player is playing in the game is a luxury hotel called "Leicester Resort Hotel". The hotel was magnificent at first, but it was actually a ghost hotel decorated by Jia Suyan, filled with all kinds of ghosts. In the early stages of the game, players can only explore a few floors. When players defeat the boss ghosts on the corresponding floors, they can get elevator buttons to other floors.
