    PSUConnI've completed this level twice on heroic and this won't pop. I also beat the par score during one run through and that didn't pop either. This is keeping me from getting the achievement for finishing Halo 2 on heroic. Anyone have any idea what's going on?

    PSUConnNone at all. Just played it straight through like normal on heroic the first time, second time the only thing I did different was put on the score tracker but like I said neither unlocked and it is keeping me from the completing Halo 2 achievements too.

    PSUConnAn update on this for anyone who has a similar issue, I finally managed to unlock this achievement and, though it, the achievements for completing Halo 2 on easy, normal, and heroic, by playing through this level for the 3rd time, and this time without ever pausing and without saving and quitting. Not sure if it was lucky number 3, no pausing, or no saving/quitting that did it, but something did the trick.

    A Ghost 0f Onyx@PSUConn, I'm having that same issue except on Legendary. I'll try your tip see if I can get it to pop for me.
