Missing Achievement - Halo 4 "The Challenged"

Hi first time poster here so all help is much appreciated.

So I've been playing Halo 4 since release date and it says on my service record that I've completed 12 achievements yet I've still not been awarded "The Challenged" achievement which is for completing 1 challenge, I've completed different challenges in Waypoint, Campaign, Wargames and Spartan Ops. Can anybody please explain this or give me any help? I've been reading into this for ages and haven't seen anybody else with this problem so if it's a glitch should I report it?

It seems like you're not the only one who can't get this achievement...


Perhaps you should try contacting the publisher(s) for more help? They can usually sort out errors and problems with their games. However, they might not be able to automatically unlock the achievement for you.

Did this solve your problem?

Sorry this didn't help.

Great! Thanks for marking this as the answer.
