[1][3][4] The game is a point-and-click adventure/shooter that was inspired by the Columbine High School massacre, putting the player in the shoes of the titular Pico, who has to fight a group of stereotypical goth kids who have killed his classmates.

The game lets players choose multiple pathways through the school's halls, have conversations with surviving students, and engage in enemy fights, all driven by mouse clicks.

Troma Entertainment were reportedly at one point in talks with Tom Fulp about making a movie based on the game.
