Your school had an apocalypse, a few hours earlier.. You were heading to the bathroom until you heard screaming coming from the bathroom you were heading.

You checked it out and saw a zombie biting a girl.. You ran back quickly to your classroom and noticed everyone wasn't there.. You slowly walked around searching for the teacher until someone pulled you into the teachers office.. It was Felix..

He said to you, "Stay here, the school is filled with zombies.."
