Black ops zombie secret
Normally in zombies quick revive is used to revive your teamats faster. But in the new zombies if you play solo you will notice that the quick revive machine is working before you turn on the power and it is only 500 Pts. Instead of its normal effect if you go down by a group of zombies you will be given dual handguns that shoot grenades, so shoot all the zombies around you and in a couple seconds you will be revived.
