We have already showed you some of the other maps for Call of Duty: Black Ops Zombie mode, we now have a map five and a walk through to show you.
This map is unlocked by beating the single player campaign, and takes place in the Pentagon where three floors are to be explored. You have the basement, on the second floor the war room, and at the top floor is the briefing room. As with Kino der Toten it is important you turn the power switch on.

The power switch is located on the basement level, from where you start open a door to the right ($750) then head to the elevator and go down ($250). Teleporters are different on this level and are activated when the power switch is turned on.
The Pack-a-Punch room you will find a Pack-a-Punch Machine which upgrades your weapons, you will also find ammunition and some pick-ups you can take. You can see the rest of the maps and walkthrough on strenthgamer.com.
