List of Luigi's Mansion pre-release and unused content

These are the beta elements for Luigi's Mansion

Beta Elements
Luigi's Poltergust 3000 was originally supposed to have a heat meter. If Luigi kept his vacuum on for too long, it would burst into flames, causing Luigi to fall backwards and lose HP. There also originally was a pink ghost that would scream behind Luigi causing him to lose 50 HP. The orange ghosts originally were light-purple with small eyes, fangs, and a different shaped head. The light-purple prototype ghosts closely resembled the final version orange ghosts and there were many more beta ghosts. There was also supposed to be more interactivity, such as Luigi sliding down a stairway, and ceiling lights falling to the floor while being chased by blue ghosts all in the foyer room. Originally, the Boo Radar was supposed to show the player where ghosts were, not just Boos. Also, the Game Boy Horror was supposed to show the player what Luigi is seeing without going into first-person view. Originally the mansion also had an RPG type of quality which included real-time changes of rooms and also an underground dungeon-like basement. There were also other cutscenes, such as Luigi looking back and seeing all of the items in the hallway move. The Game Boy Horror also had a clock. In a Nintendo Power Magazine, it was stated that Luigi had to save Mario in 24 hours or else Luigi would turn into a ghost. The clock is probably there to show Luigi how much time he has left.

There also was a lost graphic. In the first picture below shows the beta parlor but which was called Living Room at that point. In the room, it had an extra side-table in front of the china cabinet.

There was an unseen gameplay element, where whenever a ghost pops up behind Luigi, the scene will close up on Luigi would scream and in a comic style word "AAHHHHH" would show up. Luigi will end up crawling backwards in circles on the ground as a result of his fear. Also spinning coins could collected while Luigi is in the polar

The Dining Room was also accessed through a door after entering the gaint door in the foyer room then moving left.

Also, multiple small Boos were seen in several rooms in the E3 presentation, and they continued to come out of the wall like they did in Super Mario 64 and could be sucked in using the vacuum. This is a totally different method on how they act.

This game was built with the intention of being in 3D. The GameCube has built in 3D components which can be activated by an unreleased add-on (that would have cost more then the console to buy).
