Find 10 blue folders each containing a page of the exam.
Find keys for hallway A, B, C, Stairway, and Principal’s office.
When you find a key, open all doors that key can open as soon as you can.
Once you have all 10 pages of the exam, everyone (who is standing) must be at the entrance, where you started.
When you hear Lunch Lady muttering then she is NEAR.
Don’t run down hallways for a long time with Lunch Lady behind you, she will throw things (knives) and knock you down; duck into a room.
Remember which rooms have back rooms or two exits, these are best to run into when fleeing and close the door.
It is easy to miss the blue folders, and even easier to miss the keys. Keep looking.
Don’t heal yourself when the Lunch Lady is near … if she comes near when you are healing then STOP HEALING.
Don’t hide in dead-end places, you can run around tables. The principal’s office is not a good place to hide!
There’s a valve (in the cafeteria) that periodically pumps steam that can down you.
There are single-use medkits, which you can find but only carry one at a time, that can allow you to help a downed player: aim at them and hold down E until they get up, or help yourself up: hold down the mouse button until you are healed.
