Prison Pipes and Guard Booth
****************************
Objective(s): Get the walkie-talkie (primary JBA)
First things first. You have no equipment for this mission. If you don't kill
Barnham later, you don't even get a gun. The only thing you have is a lockpick.
talk about high-tech!
Right, turn around and enter the crawlspace under the bed. When you emerge,
jump up onto the ledge in front of you to meet your way into the JBA - Jamie
Washington. After your conversation is finished, let him boost you over the
pipes. Climb the ladder in front of you and open the trapdoor at the top.
Notice the yellow pipe behind you. Climb it and proceed through to the next
area. Squeeze through the narrow gaps and jump over the yellow pipes at the
end. Don't forget to hold B to soften your landing.
Next, you need to pick the trap, so do it and then drop down. Quickly pick up
the walkie talkie on the desk in this room, and hot foot it back through the
trapdoor before the guard sees you.
OBJECTIVE COMPLETE
Don't know if that's the right one. Google said it was for Wii but the walkthrough says xbox. My ball might be broken. Try yours.
