Alright I have beaten the game on legendary difficulty and I did this all in order to receive the master Chief’s suit in multiplier. But when I went to check and see if i got the Armour I didn’t. I checked all my campaign levels and it says that ive done all of them on legendary but when I check my service record It says ive only done 5? If any one could help me it would be great. Please fix this glitch I would really like Master Cheif’s suit 
I experienced a similar glitch, though I beat the campaign on Heroic. I beat the first five levels while connected to Xbox Live, but then completed the last three levels offline. While I have the corresponding achievements, my service record still only says that I’ve completed 5 missions (and thus my campaign is “In-progress,” not “Complete”), and I can’t select the last three missions on the level select screen. Has anyone else experienced this?
