I am in Davidsons room, whits way to the stealts, i have been down stiers and tunnel where i see 3 rockets, but did not see the room i got Davidsens key for.?

In the room directly to the right of the one that the Nightkin leader is in, you will find a ghoul with a sniper rifle. He's trapped, and he's guarding a computer terminal that will help you to know what to do next. Quickly! Do as Antler wishes.

THANKS
