Easter Egg: Secret Film

In the Zombie map "Kino Der Toten" there is a teleporter in front of the curtain on stage. When you use this teleporter you get sent to the room that contains Pack-a-Punch machine and a window. If you wait about a minute you'll be teleported again to one of several secret rooms. Inside the secret room that contains the presidential seal and a projector, there is a desk. On the desk there is an old roll of film which you can pick up (be warned you will not be prompted to pick it up, you just can).

Unlockable: Thundergun in Campaign

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." After the interrogation ends, look for six canisters. Toss grenades at the canisters to the rear left and rear right. Shoot the other canisters until smoke is released. 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. Weaver and Clark will move the fridge revealing a weapons cache. Here you'll find the a cassette player. Hit the action button here and you'll put the tape in the deck. You should hear music and the screen will shake and shortly the Thundergun will come out of the wall. Enjoy!

Hint: How to Beat the Battle of Khe Sanh Trenches

At the Battle of Khe Sanh, you're told to clear the trenches. What is missed by most is a nearly inaudible clue telling you that there are barrels full of napalm. And, more importantly, there's no help in telling you what to do with those barrels. Shooting them does nothing. Neither does trying to clear the trenches with one of the mounted machineguns, as the Viet Cong keep pouring out in an endless wave. Nope, you have to run to two of the giant, striped barrels near the bottom of the hill and kick them down into the trench. There are two of them. Hide behind the sandbags and take shots at the VC until it's relatively clear. Make a run for the nearby barrel and use the prompt to stab it and kick it down the hill.
