Please note that the first DLC for Halo 4 , the Crimson Map Pack is now available for download. The pack, weighing 528 MB ( link Xbox.com ), will allow you to add new maps and modes for 800 MSP or free for Season Pass holders. The latter, however, have had trouble downloading it without additional charges: 343 informs us via Twitter to be aware of the problem and of star working with Microsoft to resolve it. From the coming hours Season Pass owners should be able to download the content.

Update : the problem with the Season Pass is now resolved.
