Bad Brother- Instead of heading to the cave to defeat Alice, casting out all the ghouls of the mansion, bringing Mario back, Luigi continues through the path to fight King Boo. No matter how well you do during your run, no matter what you collect, choose, you will always get the bad ending for going down this path. Mario's soul is erased, he's gone, because without the poltergust? Luigi is nothing against him. Luigi, and whatever partners he had (if any), sit in the empty arena, forever. Forever, Missing-

Missing v2- Basically the same as (Mario) The Music Box, nothing different here. So yes, MTMBArc (the original) is canon in this mod universe if you get this ending

You Murderer.. (achievement method will change)- Luigi loses it, and goes rogue. Killing whoever in sight he sees, his partners, and even goes through with killing both King Boo and Alice. He slaughters Riba last before fleeing to the parlor. (Achieved depending on player choice throughout the game)

Sweet Dreams- Riba, you scumbag. (Go deeper into the mansion instead of the cave or forest. The door to this ending will be locked if you do not have at least 1 partner.)

Puppet (Luigi Mix)- Alice repossesses Luigi, tricking the two into thinking she's gone. She waits until the two escape to their home to go on a killing spree across the kingdom. (Only take 1 partner the entire game with you. Except for...)

Sealed (Mario Mix) [PLANNED]: Alice tries to leave but is stopped by MIPs, who can tell she will repossess him again, figuring out earlier the music box was the root of all the problems. In return, Alice takes Luigi's body and makes him fall off the cliff, to his demise. MIPs is thereby Luigi in his final moments, waiting for a search team to come with Mario. Mario falls into immense grief. (Take MIPs as your only partner, nobody else.)

Better Off Lost- basically the same as the original game. (Save all partners, make good choices, fight Alice instead of King Boo)
