2. Corpse Party - PSP
This ones from Japan, it's a portable game and its also a 2D adventure game. Its also very scary and disturbing. Its about a school thats been built on the grounds of an old school where some disappearances and unpleasant murders occurred and a group of students cast a ritual that transports them into the older school (Heavenly Host Elementary) causing them to fight for their lives as ghosts try to kill them at every turn. There are lots of endings, the animation is creepy as hell and the story is extremely well written, just dont be surprised if you get the worst endings first. You can get it on the Playstation Network and I recommend you to play it under the sheets with a good pair of headphones.
