you must be a survivor to do this as you cant do this as the killer. so when you are a survivor first you must fully repair a generator all by yourself. if anybody helps you with the generator go find a different one. when you have repaired the generator hide in one of those red closet things for 5 minutes then come out and go find the killer. when the killer hits you you must quickly go back to the generator that you repaired all by yourself and stand next to it. when the killer is about to hit you again you must quickly spam alt+f4 and you will slowly turn dark with scary noises and rise up into the sky. you are now the entity!
