Bungie Day means free Halo 3 map and other goodies

Coming July 7

On July 7, otherwise known as Bungie Day, Halo fans will be on the receiving end of a new Halo 3 map, gamer pics and a Bungie Day Xbox 360 dashboard theme, all for free on Xbox LIVE Marketplace.

The new map, called Cold Storage, is a multiplayer affair inspired by the original map Chill Out found in "Halo: Combat Evolved."

"The Cold Storage facility was once a vibrant, active research center on Installation 05. An accidental contamination resulted in an unforeseen outbreak, which compromised the Forerunner center. Now, emptied and silent, watched only by a local caretaker, the abandoned structure serves as a reminder of how something as powerful as science is ultimately beholden to nature," read a Bungie press release.

In addition to the new map, players will be able to download seven gamerpics and a Bungie Day dashboard theme from Xbox LIVE Marketplace.

Fans will need to be sure they download these on 7/7, because they will be available for one day only, Bungie said.
