12 more Easter eggs from Call of Duty: Black Ops

One guide wasn't enough. Within minutes of posting our "complete" list of Easter eggs in Call of Duty: Black Ops, the internet had already discovered many more. And as the article's comments section made clear, so had you.

Here, then, is part two of our guide to Call of Duty: Black Ops Easter eggs - 10 more secrets and surprises awaiting the truly dedicated and determined gamer. Did we miss more? As always, let us know below!

Hidden film reels in "Kino Der Toten" Zombies

No doubt you've already figured out that the German "kino der toten" translates to "cinema of the dead" in English, which explains why this Nazi Zombies map is set in a decaying, infested theater. But did you also know that you can change what's playing on the movie screen?

Gather three friends and fight until you unlock the Pack-a-Punch projector room, which is above the main door to the theater, but is only accessible through the Teleporter on the stage. If all four players are in this room at once, they will be teleported to random rooms across the map, then given a few seconds to search for a hidden film reel before being teleported back.

Once back, pop one of the reels – there are three total – into the film projector to see and hear creepy new clips on the screen below.

Eminem in "Five" Zombies

See that bright red telephone in the image above? You know, the one that looks like a direct line to 1960s Batman? Find three of those in "Five" Zombies and you'll actually reach rapper Eminem… or, to be more exact, his music. Hold "X" or "Square" over each of the red phones in this map and Eminem's "Won't Back Down" – the song you heard during the campaign's credits, featuring Pink – will begin playing over the Zombies match.

Check out the video above for the exact locations of the telephones, after which you can dance your undead troubles away. Though considering who and where you are during "Five" Zombies, a more era-appropriate track would have been welcome. 1960s Batman theme, perhaps?

Secret song in "Kino Der Toten" Zombies

This Easter egg works exactly like the Eminem one in "Five" Zombies. Instead of searching for red telephones, however, you should be looking for meteor rocks that glow with alternating color. They're a lot harder to see in this darker setting, too, so check this video for exact locations:

As you find each meteor rock, hold "X" or "Square" until you hear your soldier remark on the discovery. When you've tracked down all three, a song by Elena Siegman called "115" will begin to play.

TSA: Treyarch Security Administration

You're not really in control during the U.S.D.D. mission of Black Ops, but you are allowed to turn the direction of your head ever-so-slightly during this Pentagon walkthrough. That's how you might have noticed, while walking through the Defense Department's security checkpoint, that the metal detectors are branded with official Treyarch logos. NHL, Tony Hawk, Spider-Man, Call of Duty, metal detectors… is there anything these guys haven't done?
