Overview
This is my first guide so don’t expect much.
Tips
1: When the lunch lady shrieks she knows where you were at that moment and heads over to that area also when you get over 5-6 pages on normal each new one makes her shriek, the number goes down the higher the difficulty.
2: The lunch lady will throw a knife in a straight line during a chase which you can dodge by well strafing which is what I do, they also go through doors for some reason.
3: You can identify her with a red glow that is around her and her noises.
4: Keep every door open that you can.
5: Stay vigilant when looking for keys and pages I have found myself doing this mistake plenty of times and missing a page.
6: Watch out for steam pipes they can burst and down you, you can also turn them off with a valve.
7: You can revive yourself with a medkit by holding left click and revive teammates with right click, medkits become more rare the higher the difficulty.
8: When you run she will go to your location (still not sure yet, so take this with a grain of salt)
