I bought the le of 4 redeemed all the codes and i still dont have access to the crimson or majestic map packs. Am i doing something wrong or have i not done something??
Have you downloaded them from the in-game marketplace?
You have to download them from the main menu of halo 4, just go to the option marketplace from there.
They need to be downloaded directly from the marketplace. But as long as you have the Map Pass, you get them for free.
The 3 above responses are correct, OMAC1. Please try to download the maps from the in-game Halo 4 marketplace and you should be all set.
