G-120 acts like A-120 but slighty more dangrous. He appears in the current room out of an portal and then G-120 comes out of it. Then G-120 will break any hiding spot your in if you are in one. before he breaks it he will kick you out of it before breaking it. then he will go to the center of the room and spawn ANY G-Section Entity. it can also pick G-177 but when he does that he will automattcilly spawn in the mimic without the computer spawning.
