I used XPGSensi420 starter save http://www.xpgamesav...e/#.UJwkQ2_A-PQ I used his started save and continued with the main missions to get the: Perfectionist 100% Main Mission Sync If the achievement does not unlock, then replay any mission you know you can get 100% on. That should pop it up then. http://www.mediafire.com/myfiles.php#bs29cxbx96nsd
