Achievement Glitch

Games Other Halo

343i,

I have completed the entire campaign, on Legendary, solo. I did not ever get awarded the achievement for doing this. Any way we can look into this to resolve it? I would rather not have to replay the game, to receive things I have already earned.

Thanks a bunch!

Did you watch the prologue and epilogue and were signed in to Live?

I will give it a try. Thank you.
