Luigi's Mansion Unlockables

Finish the game and save. Go to the lab. Professor E. Gadds will ask where you want to go. Select the hidden mansion to play the game again with various differences.

You can get a different sized house at the end of the game, depending on your rank.

After finishing the game you will unlock everything in the gallery.

To obtain an "A" rank, get all the gold mice, catch all the blue ghosts, get both gold diamonds, and collect as much money as possible. You need $100,000,000 to get an "A".

There are three different medals you can collect to change the powers of the Poltergust 3000 vacuum cleaner. They are the Fire, Ice, and Water medals. When you collect the Fire Medal, you can suck up ghosts that have a ring of fire around the health hearts. Also, you can press L to spray fire from your vacuum to light candles and hit ghosts with a ice health meter. When you collect the Water Medal, you can extinguish flames that are too powerful for your vacuum to put out. Also, you can press L to spray water.

To unlock the tent, complete the game with less than 5,000,000g. A hint to doing so is to collect nothing but king boo's crown.
