Trying to play Halo 3 on Xbox Live?

[Daniel W]

To play on a mode such as social big team it says I need non-cold storage DLC.. What is this? I've downloaded most of the free stuff I can, so if you have to pay for it could you tell me which one and maybe how much it costs?

Thanks for your answer

You need to have the Heroic, Legendary, and Mythic map packs. They are all 800 ms points per pack. thats basically 30$ worth of ms points
