Professionial Activision, umm, guy Dan "One of Swords" Amrich has posted nine interesting secrets from Call of Duty: Black Ops' multiplayer map Nuketown. Sure, everybody probably noticed the double rainbow all the way across the sky (what does it mean?), but did you notice the names on the mailboxes, or the fact that the town clock and population board actually count the actual time left and players present in the match? There's also a few secret RC-XD hidey holes (seen above), and apparently Nuketown isn't the only map with a few secret places to send your buzzing remote controlled car of doom.
Say what you want about Activision's evil empire or the money-making steamroller that Call of Duty has become, but no one can say Treyarch didn't pack the stuffing out of this game with hidden content.
