Call of Duty: Black Ops

Find the three meteors. The first meteor is located on a pedestal in a corner behind the soda in the main lobby. The second meteor is on a pedestal in the dressing room near some mannequins. The third meteor is the room upstairs near the alleyway, on a "dresser" with black marquee letters. Note: The meteors appear as red veined rocks. Hold [Use] on each meteor until your character says something or the veins in the rock glow red. After all three are found, the song "115" by Elena Siegman will play.

Shoot the heads off all the mannequins in record time to hear "Sympathy For the Devil" by the Rolling Stones.

In the level "Numbers," after interrogating Clarke, several enemy soldiers will appear at the end of the long hallway. If you can shoot all six Nova 6 canisters (two in the back, four on the sides), you can retrieve a cassette tape in the office behind where you started. Note: It is recommended that you toss a flashbang to blind the enemies so you have less trouble taking out the canisters. Once you pick up the tape, continue with the level until the part where Weaver and Clarke both jump off the roof onto a mattress. After they jump down, Clarke will ask Weaver to help him move a fridge out of the way to his first weapon stash. Once they do, go inside and look to the left. There should be a place to put the cassette. Note: When picking up and placing the cassette tape, the game will not prompt you -- you must have seen it being moved yourself. After that, the screen will shake and the Thunder Gun will appear out of the wall. It has twelve bullets, and it is reloaded at checkpoints.
