Dust off those Halo 3 disks and get ready for a new map... for FREE!

In honor of "Bungie Day", which takes place every July 7th, Bungie is releasing a new map "Cold Storage", which was inspired from the map "Chill Out" from Halo: Combat Evolved.

In addition to a new battleground, the Legendary Map Pack will be discounted to 600 Microsoft Points, but only for the 7th. Players will also find "7 exclusive new gamerpics and a Bungie Day dashboard theme for free on Xbox LIVE Marketplace. Fans will need to be sure they download these on 7/7, because they will be available for one day only."

Good thing the 7th is Monday so you can enjoy all this great free content over the weekend... Oh wait, you can't! We love tradition, Bungie, but we love long weekends with new DLC more.
