Zombies/Why did I lose my perma quick revive?

I think the answer to your problem is that you died. When you die you lose all your perks, so you will have to buy it again sorry =[ I think the quick revive revives teammates faster not multiple times. The perks last forever until you fall or die.

No, he's talking about the Permanent perks. I don't know honestly.

If you don't play online for a few days or you back out of a game before the game ends you lose everything now. NEW UPDATE and if you back out more then three times in a week you won't be able to play online for that week so good luck to everyone who backs out of a game(bettlejuice911 xbox live) if you want to play black ops 2 with my team??????? send me a txt to the game tag above

The whole thing is very strange, no one knows for sure how it works, a lot of people were saying that with all of the perma perks =D

I was in a game with one of my friends and he lost it in the middle of a round for no apparent reason. He had not been downed the entire game either.

To get the invisible permanent Quick revive you ahve to revive teammates 15-20 times in one game, then you will get a greeen flash. You will keep that upgrade throughout multiple games. The way you lose it is by starting to revive a teammate but then get interupted and stop. Then you have to do the process all over again.

There are a few other permananet upgrades such as
Headshot - Get 2 headshots with 1 bullet - increased headshot damage - (lose it by not getting headshots for a while)
Extra Health - So in a solo tranzit game and buy quick revive, get downed and repeat the process until you see a green flash - take 4 hits instead of 2 - (lose by making it to wave 15)
Metal Barriers -Repair around 50 windows in one game and get points for it - Replaces wooden boards with metal ones that take zombies longer to pull down - (lose by not repairing any windows for a wave or 2)
Metal Carpenter - Get a kill while a carpenter is repairing the boards - Repairs all boards with metal boards instead of wood when carpenter is obtained- (don't knwo how you lose it)
Red INsta Kill - Pick up and instakill and dont get any kills, then get another instakill and dont get any kills, at the end of the second you get the green flash - Effect: when you get an instakill there is an extra red skull, while this red skull is active if you touch any zombies they die. - (Lose it by getting hit whileinstakill is active, doesn't matter if it's red or not you will lose it for next time)

It is not Permanent.

It isnt permanent.

crazycodyo just answered it all pretty much, I never new about metal barriers or metal carpenter. I will have to try them out, but the rest is all legit.
