Danganronpa: Trigger Happy Havoc is a 2010 game created by Spike Chunsoft. In this game, 15 students get locked in the school, and they have to resort to killing to escape.
When a murder happens, the class will investigate the crime scene and eventually have a "Class Trial", which ends with voting.
If they correctly identify the murderer, the murderer will be executed. But if they misidentify the murderer, everyone except the murderer will be executed, and the murderer will graduate.
Danganronpa: Trigger Happy Havoc is pretty dope
