Once of you get to the pipeline you are sent down and go into a Hyperbaric Chamber All of you need to pull a lever to open the pipe and it's stuck on tight so you go back up to the surface to get a wrench to open it. You head back down and hand the wrench to one of your friends and he opens it. You all get sucked in the pipe and you're in a long breath hold as you are sucked in this really tight pipe. Then you stop and your in a air pocket and here one of your friend yell Is everyone alright?!
