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."
Make sure and check out the Halo 3 pictures area to see some screenshots of the new Cold Storage map!
