As a token of our appreciation and to thank fans for the continued support and understanding, we will be offering the following items..."

Halo 3: ODST Campaign: The original Xbox 360 game campaign will be upgraded to run at 1080p and 60 FPS. Development on this "just started," but 343 says we can expect to see it in Spring 2015. There are no plans to include the co-op Firefight mode. The campaign will be delivered through a free download token, and you'll launch it through MCC.



One month of Xbox Live Gold: This will be delivered as early as mid-January 2015. 343 will either apply one month of Gold directly to your account or send a redeemable token through the Xbox One message center.
