For the people that don't know how to use these codes, just log into halo waypoint, and then go to the classified section to enter the codes. You can also do this from waypoint on the 360 apparently, but I've never done it from there.
YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS finally i can get some more credits so i can get some sweet armor --- wow strafing tryhards, i always stand still so the bullets can hit me. Whenever someone trys to dodge my shots i know they're a virgin LMAO
its happened to me i am back to sr1 and cant level up or use loadouts
well, poop... This SR1 glitch has been happening a lot lately. Just need to sit and wait for 343 to come up with a fix I guess. I HAAAAAAAD to use an XP only code when I was already max rank... Hopefully it'll be a quick fix.
