Ever since the nightmare dlc tried to update it and it redownloaded my game, now it stops around 21% ive been retrying to download for over a month amd still no luck all I wanna do is play and so far i would like a refund since im unable to play but my friends can. How xbox (not blaming 343) screwd up I have no clue but im unhappy and would like an update on whats going on (ive seen other forms i know im not alone) i feel as if halo fans are always getting toyed with even if its not 343

Please see the 343 response thread in this forum for the latest updates on this issue. The first post has been updated and there is additional commentary in the last few pages
