Music Easter Egg
Secret Music Radio
Go into the room with the "Help" door, where the Mystery Box spawns. To the right of the box is a radio. Knife or shoot it to start playing a random track.
Version Differences
On World at War, the radio plays music pulled from the campaign, including "Black Cats" and "Red Army," along with "Königgrätzer Marsch" and the map's own song, "WTF" by Brian Tuey and Kevin Sherwood. On Black Ops 1, it instead plays music from the Black Ops 1 campaign and Dead Ops Arcade. On the Black Ops 3 Zombies Chronicles version, it plays songs featured throughout the various Call of Duty Zombies maps.

This track was added in the Black Ops 1 version of the map and isn't present on World at War.
Shoot the 3 different red barrels found outside of the map.
Once all 3 have been shot, "Undone" by Kevin Sherwood, the remastered map's song, will begin playing.
