It was just another morning. A peaceful morning. But inside, the school has turned into complete and utter chaos.

From the very beginning. Graaaargh! Everything is turned upside down. Zombies. The kids realized they were zombies and tried to run, but it was already too late. It spread so fast before anyone noticed that running was useless. Guest was walking down the hallway. Guest realizes... 'Oh, I'm screwed...' That's right, you're screwed. Guest's footsteps stop. You freeze. You try to run, but your feet won't move.
