A really twisted horror anime / anime game?

Corpse Party. It's a PSP anime horror game.

i know a game its alice in wonderland one

Mnemosyne aka rin daughters of mnemosyne is pretty sick and twisted and is horror. Cannabalistic angels, consensual rape, twisted forms of torture, and lots of blood and gore. It does have nudity in it but no lower private parts are shown and there are a lot of lesbian moments so if tu don't like those don't watch it.

Personally I loved it and I hope tu will too. The computer isn't readily available at the moment but I'll come back and post a picture o better yet the trailer of the show.

EDIT: lol that was fast now wasn't it? :3 I'm going to post the English Dub trailer because I don't think there's a Sub trailer and it best describes the mostrar rather than a picture. But tu can watch it in subs if tu hate dubs o just prefer subs. link definitely has it under the "M" as Mnemosyne for the subbed version and link has the dubbed version under "R" as Rin: Daughters of Mnemosyne.

High school of the dead

hellsing(top left)
shiki(top right)
baccano(bottom left)
elfen lied(bottom right)

hellsing ova is about the hellsing orginization who are manly humans and two vampiros that r fighting a large vampire nazi group and the ova is better then the normal hellsing

shiki is about vampiros who come in a town and kill people but only 3 people know they r vampires

baccano is about america in the 1930s and its about the mafia and some characters are immortal so one kid got shot in the head with a shot gun twice his head was totaly destroyed then all the blood came off the muro and reformed his head

elfen lied is about people who have invisible arms on the back that vibrate at such i high speed they cut through people like butter!

Ghost Hunt is a good horror series~
Also try: Boogie bop Phantom
darker than BLACk
Phantom requiem Of the Phantom
Shiki
Gantz
And Le Portrait de Petite Cossette~

Elfen Lied, the first Horror anime I ever watched and differently one of the best Animes I've ever seen.

tu may want to try the anime/manga Monster. It's really good!

I DONT KNOW IF IT IS REALLY SCARY.?!!~
