RTDM sp 3rd party map exit?

[Heavy Medal]

I have tried several times to locate the exit to rtdm after killing all the zombies and finding a switch that doesn't seem to open anything. I've read other posts on another site saying same problem, but I see no replies. Anyone know?

There's the room with like 4 or 5 doors, the room you see in the opening animation. Have you found the hidden switch in that room? If not, there's some ammo on the floor near a wall in that room, look on the walls near that ammo for the switch, it's well hidden. Hope this helps.
