Much like the Ray Gun in the previous game, the Thundergun can be unlocked in Black Ops by performing the following specific actions on the level "Numbers."

A black tape will appear out of a cassette deck. Grab it with the action button. Leave the room and head upstairs. Kill everyone and move to the rooftop and jump to the next floor.
