And I've only ever played my own homebrew horror games. If anybody recognizes F.E.A.R. and the effect they used when peoples and ghosts would dissipate into ash floating upwards with slow-motion sequences I loved to use that a lot. As well as TV's plugged in and trying to get signal but only giving off static.
Oh and manaquins randomly appearing behind you with weapons in their hands much like Condemned.
Exploding baby dolls never made it into my game but I tried.
DID have an insane chick with a mask, blood red outfit, bloody stained bandages, and a chainsaw chase my players through a zombie infested dam once though...she was fun.
Feel free to steal her since I stole her in the first place.
^^ That with a chainsaw and an echoing laugh through a broken and collapsing zombie infested dam.
...I have to go and clean myself real quick.
