The New House | Main missions Wolfenstein: TNO Guide

At the beginning of the mission, jump into the water and follow the rest. Once you reach the manhole, cut through the chain with the blowtorch and swim inside. Now, you are in the resistance's HQ. Your first task is to bring back the documents for the girl in the wheelchair.

Climb up and ask Klaus if he has them. He will tell you that he put them in place several days ago. However, you do not need to go there.

The documents are in Max's room

Still, you need a crowbar., which you can find on the upper floor in Thimbault's room. This is what it reads above the door. After you obtain the crowbar, go to Max's room and smash the board on the wall to retrieve the folder. Take it, then, back to the owner, which starts the next mission.
