Diffuculty:easier then a rip-off game

-The screen will darker so you have to find him in cameras

-Charge the power more often

-Once you see his face in a camera you have to change the camera

-Reboot system If he appears at office

-Listen for his knock,that means he is in both doors,close BOTH of them

-Shine the light at him If you hear his laugh or you already see him in hallway

-He will make some vent noises If you hear it put the mask

-Once you reach 4am he will take your half of the power (the same thing with 6am when you reach it)

-the screen will darker and you hear knocking close the doors first then find him in cameras (you have to do this If you are in this situation)

-If a camera start glitching change another camera or pull down the camera (this is rare to happen)

-If he appears at office and appears at doors and screen being darker,fix the system first then close both doors and then find him in cameras (thats a rare happending situation so you have to do this If you are in that situation)

-Dont worry he will NOT appear at ceiling vent

-You have to be very attention

(of course I beat that easiest night in 2nd try so it will be not hard but you have to always be fast)
