i use ps3

need 3 bloodthirsty and 1 longshot to get an-94 gold

i need 21 headshots with Swat but bro is on it now so he could get them.

An-94 will be last Assault rifle i do i think but should be master prestige by then (level 40 now) anyway so i wouldn't need to unlock any guns

Keep getting 4 kills on trot then dying with the Ballista

got the same.. hate that

In past 2 nights i think ive got 9 of them

Still need 9 more bloodthirsty kills

need 1 bloodthirsty kills, with an-94..

same with us for SMR, would have got it earlier if teammates didn't run in their spawn which meant enemies spawning round me and a 1 shot gun doesn't stand much chance.

After that just M8A1 and AN-94 for Diamond Assault Rifles. With Ballista we are on like 210 or 220 One Shot Kills using Sniper with Acog is so fun.

We are Master Prestige as well now so we get all the unlocks for perks, equipment, wildcards, scorestreaks and weapons (basically anything you can buy with an 'unlock token')

Well twice its happened now but i have been completely reset for absolutely no reason. Nothing popped up to say why but iv lost 9 gold guns now due to it. Really put me off my gameplay so probably wont be attempting to get any diamond camo's now.

also tried out the survival mode today for the first time. My favourite is the map with Tranzit on it (64 kills, Round 6), second was Farm (50 kills, Round 5) the third well i did pants was playing on my own though.

thats harsh , maybe appeal to Treyarch over twitter? i would be annoyed if i lost my 19 (almost 20) gold guns. I would probably even reattempt Modern Warfare 3 on Infected or something.

Only plus is its only the 2nd/3rd Month of release so you can easily regain those stats.

I only played survival on town. Round 25 solo was my best with i think nearly 700 kills. I only played Tranzit to get the Tower Of Babble trophy but that was really annoying to get.

On the black ops 2 site there are some of the developers on there and loads of people have had the same as me. Iv messaged them to try get my stats back. It would be pretty easy to get them back (apart from getting the headshots which are really annoying) I suppose i could start again.

assault diamond will update when comp can connect to net

Finally after talking to Treyarch they admitted that they reset people by accident and have gavve me my stats back but only from the 2nd time they reset me. Im not back to my highest but they did put me back to 2nd prestige. I have all my gold guns from before. I dont mind being 2nd presige again. The only downside to it is that i have lost all my titles and emblems and the gold guns are back to prestige 2 level 1 again so i have to re do that last prestige with them. Im just happy i got my stats back.
