Here is my Glitch Report:
Did the achievement glitch on your account?
Did you start out on SuperSoldier Difficulty?
Did the Veteran 3/7 achievement unlock?
Did you access the tutorial from a new game or through the menu?
Prior to campaign completion, did you replay missions through mission select?
If it didn't unlock initially, how did you finally get it to pop?
I DIDN'T GET IT BY NOW!!
Did you press the X button to skip cutscenes either at the end of a chapter or during a mission briefing?
I hope someone can help me - that stupid achievement is the last one i am currently missing!!!
(and no - i definitely don't play the game a fuckin 4TH TIME except i know a 100% that it will work!!!)
