To turn the television in the center of Nuketown into an Atari gaming screen, you have to go into a custom match (By yourself or with friends). From there, once the match starts, you have 2 minutes to shoot off every head of the mannequins! There is 20 of them, and every time you try, they will randomly spawn. Always look outside of the map too.

There is a secret Easter Egg/video at the end of the Black Ops 2 credits sequence. When you complete the game, be sure to watch through to the end of the credits. The developers have hidden away a humorous video there to reward people who see the full list of those who contributed to this epic game!

To do this you must get the gold camo (unlocked when every camo but it is unlocked for gun) on every weapon in a group (for example: get gold on crossbow and ballistic knife and you will unlock the diamond camo for only the crossbow and ballistic knife).

"In TranZit, kill one of the denizens of the forest while it is latched onto you."

To get this achievement you need to be in Zombies mode, playing a TranZit game. Open the main doors and then run out into the wilderness, into the smog until you see a skull and crossbones sign out along the road. It is around here that the 'denizens of the forest' will emerge.

Once one latches onto you, use the right stick to melee it. It will take about 5 swipes to kill it and get the achievement.

Once you reach the final mission of Black Ops 2, as you enter the round office complex, look to the left and you should find a Mini CLAW just sitting there on the floor.

When you revive the same teammate at least 15 times in Transit mode a green flash will appear from the revived teammate to indicate that the perk has been permanently unlocked for use in Tranzit mode.

It is possible to see Thor's hammer in a particular level on Black Ops 2. To do this, you need to be on the Celerium mission (level 2). Play through until you get to the point where you fly in using the special suits. Once you have landed and killed all the initial enemies, go to the cliff and drop down to a lower section. You should see a dark cave that you can go into. Light it up with gunfire or flash bangs to see the hammer.

During the courtyard section with the bell tower, you may find that you are unable to continue, with the game seemingly glitched. It is in fact waiting for you to kill everyone in the area - search all the corpses. You will likely find one that is still alive. Finishing him off will allow you to proceed. That, or kill yourself and restart the level.
