Play the first mission again, that's what my friend did to unlock it.

okay ill try that!

did it work? it wont unlock for me either

If you didn't get it it's purely because somehow you didn't play through the whole game. I replayed the game from the first level (on the sub) because of course it's part of the game. I played it right through to the end and got my two achievements.

no playing the first level again didn't work, and i played it on super solider from the sub.
