Haunted Mansion stuffz
-Once you go in, if something somehow 'kills' you while inside, you "respawn" out front of it the next day. Just so you don't need to worry about having to wait a week if you feel extra mean.
++ If you get a OMG epic wound while inside, and make it out alive, it will magically disappear.
-Indestructible! You may be able to nuke a planet, but not this mansion.
++ However, things inside can be broken/knocked over/smashed, but may not end well.
+++ Doors are a case by case basis depending on how mean you feel. Also slam shut without warning.
++++ Also, if you play a fearless bastard, your character's powers can randomly not work, or their weapons malfunction, etc, etc. Just so they can worry a little.
-Bigger on the inside than it looks! Comes complete with a basement of unspeakable horror.
++ On that note, the layout changes every time you go inside! No tour guides here!
+++ And yes it IS possible to just walk back out the front door if you can find your way back to it. Nothing chasing you will follow you out.
So! Some ideas for stuff that is inside!
-Ghosts! Possession capable ones, if that is your thing.
-Floating furniture, bleeding walls, mysterious paintings that come to life or change, etc, etc.
-Creepy statues! May or may not chase you down upon approaching, or may just turn to stare at you as you walk past!
-Hearing things they aren't really there! Screaming voices of people you know, footsteps following you, the sound of metal chains, etc, etc.
-Random bodies! Dressed as people you know, or dressed as you!
-On that note, feel free to see someone you know walking around, when it isn't really them!
-Monsters from horror games can come in droves, if that is what spooks you out! Silent Hill monsters would fit right in.
blah blah feel free to add whatever you want--!!
