Call of Duty: Black Ops II

In the map Nuketown 2025, shoot all of the heads off the mannequins within two minutes of starting a game. Now if you go to the Nuketown population sign, you will be able to press square and play four vintage Activision games on the screen.

In Tranzit, go into solo, buy quick revive(Solo cost:500, Multi-survivors cost:1500), down yourself, because your in Solo, quick revive revives you, so down yourself again and you'll get a green mist like in perma-per:quick revive, but instead of quick reviving, you can take 3 hits by a zombie, and if you combine juggernaug and perma-perk:juggernaug, you'll get juggernaug pro, which instead of 5 hits with juggernaug(drink), you'll handle 6 hits before getting downed on the 6th hit.

Getting a collateral head shot with one bullet will permanently unlock Deadshot Daquiri. This perk will increase the head shot multiplier in zombies and is saved to your profile. To confirm you have this simply shoot a zombie anywhere but the head until it dies, if the head is magically blown off, you indeed have the perk.

Note: This only works in tranzit.Revive the same teammate 15 times or more in the same round. You will then notice a green flash pop out of your teammate, meaning you unlocked it. I recommend doing this in round 1. Now you can revive your teammates faster without buying the quick revive perk. This unlock will be saved in your profile troughout your future tranzit games.
