I play on Xbox 360, my gamertag is gcode987 and my Microsoft live account email is [MOD REMOVED]. I play the Call of Duty Ghosts game and have recently downloaded the new Onslaught DLC. In the DLC there is a new Extinction game map called Nightfall. I have found all the Intel in "search boxes and computers" and have 15/15 when I go under Intel in the Extinction game mode. However for some reason I did not receive the "Undiscovered Truths" achievement which states you need to find all the Intel in the new Nightfall Extinction map (which I have done). There are 13 pieces of Intel you recover in the game, a prologue and an epilogue which equal 15. When I enter the Intel menu under the extinction game mode menu I see all 15/15 however I do not have the achievement. I have tried restarting my Xbox several times with no luck of unlocking the achievement. I would like to get the achievement as I have completed the task for it. My gamerscore is also at 19990 and this achievement will but me over the 20k mark! Any help would be greatly appreciated.
