Walkthrough[edit]

Swim on through the tunnels. Enjoy the banter as Steve picks on Michael and Dave. It is a long swim so expect it to take some time. When you hear an airpocket mentioned being above you, that is your mark to start on upwards. Go for the Northeastern corner and climb on up the ladder there.

Go on through the first door. There is a scientist on the other side. Equip the stun gun and zap him. After that continue down the corridor. When you reach the bend in the corridor, another person will show up. Once again, zap them with the stun gun.
