It's prone to freezing if people ad-lib in a certain location, I believe most typically by hallway you can access by crawling under burning wreckage in lower level.I am having the same issue on Hellfire with 3 other players. We can't get past the early part of the game. It seems the fire room you have to crawl through the room after that I froze on. And sometimes freezing only affects one player but not sure if they have a hardware memory problem because their game mem card bugs out. Has anyone dealt with this recently?
