So I got up to just before the power up Chapter of the game, and right as Gargantua comes into play killing off the military, Now what happened was I let him do his thang and kill the insensitive pricks, and well he came right up to the door of the hallway I was waiting in, shot his blue ray of death, then just stood there, and wouldn’t move, i could attack him, shoot him ect, to no avail ofcourse, here is a screenshot of me up close with him
And here is one about 5 seconds later after me hitting him and scrolling through my weapons again
I Will admit, whilst it was AMAZING! that he stood there so I could near Jizz over the detail and amazingness of him, It was rather hard moving further through the game with him just chilling right in my way
