Acheivment not unlocking

Hi, I am playing call of duty ghosts and there is an acheivment called atlas falls, it is for completing the level atlas falls on any difficulty, I must have played the level about 9 times start to finish but still no acheivment, I know this is only a small
matter but it's kinda frustrating. Thanks

:)

 

Halo acheivments not unlocking

so was playing Halo 4 in the Master Chief collection. Went under the bridge and accessed terminal and no acheivement unlocked. Completed first mission and no acheivement unlocked. Went to career and picked the first achievement and picked the option to take
me to the point where I can get the acheivment tried again didn't unlock again. Finished mission again and no achievment. Normal game mode. Did unlock killed 100 grunts so I know that some achievments are working. Have completed 8 total Campaign missions
but didn't unlock any of those acheivments.

Achievments have never taken 48 hours before. The link is less than useful as it is directed at the matchmaking issues and deflects other problems as system issues. I have never gotten a finished unlocking message. Have now tried the Digging Up The Past
acheivments 8 times. Still hasn't unlocked. Keep trying it since it is one of the easiest and you can take the acheivments link almost direct to it.

 

Four or five level Achievements wouldn't pop for me even though I beat the game in more or less one sitting.

got that from Microsoft support worked for me.

So did that restore the acheivment or did you have to re unlock it?

 

I am not sure if an xbox worker just did something but thanks if you did cos the acheivment just randomly popped up 5 missions later.
