I am here to talk about this excellent title that is "Corpse Party ", at least for anyone who enjoys a good story full of twists and dramatic developments!

The story of Corpse Party is about a group of high school friends in Kisaragi Academy. Kisaragi Academy was built on the grounds of Tenshin Elementary School, which was demolished after a string of disappearances and gruesome murders. After a mysterious earthquake, the students find themselves trapped in an alternate reality inside Tenshin Elementary School, where the murders of others trapped before them have continued unabated...

This game is based on a manga called Corpse Party: Blood Covered, and follows the horror story of the arrested students in this grim reality as well as in the manga.
The difference is that in the psp game you start following the story of two of the protagonists and finishing the chapter one you come to see the story of another character (and so on until you see all the characters and the different angles of the plot).

(They are stuck in the same place but each one in an alternate reality, where only a few small interactions with each other can be made).

It is extremely difficult for this to be translated into English, unfortunately because this game has a story that holds you from start to finish.
There is a version of the PC game available on the Internet translated, but unfortunately is only the first chapter so i do not recommend, you will play, get addicted and get frustrated wanting more like me =/

Finally, stay with some images from the manga and a video that i uploaded here on gamespot. cya o/
