“7/7” has long been heralded as “Bungie Day” by the Bungie fan community. This tradition was born in part due to the significance the number 7 has played in all of Bungie’s games over the years (including the Halo series – which happened to involve 7 Halo rings, “343” Guilty Spark, Master Chief is Spartan 117, etc..). 

This year, 7/7 will bring a few special treats to fans of Bungie and Halo but some are only available for a limited time so you’ll need to act quickly…

Commemorative Gamer Pics – on 7/7, fans can download 7 exclusive gamerpics, for free, from Xbox LIVE Marketplace. These are only available for one day and then they’re gone forever.

In addition to the pics, you can also obtain a special Bungie Day dashboard theme to adorn your Xbox 360. This too is only going to be available for download on 7/7.

Cold Storage, an update of Halo: Combat Evolved multiplayer classic, Chill Out, will be available to download for free. The emptied Forerunner research facility serves as a grim reminder of how even the best laid plans can fail. Warmly crafted, dutifully beautified update of Halo: CE classic multiplayer map, Chill Out. Love, Bungie".

Once, the Cold Storage facility was 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.

Starting on 7/7, the Halo 3 Legendary Map Pack will be available to purchase a new low price of 600 points. If you’ve yet to experience this epic collection of multiplayer battlegrounds, the time has never been better.

4th of July Weekend kicks off a special “Fourth of July” playlist where players can earn double-XP competing in a variety of Halo 3 gametypes (7/3 – 7/7).

On 7/7, the “Icy Treats” playlist is released which consists of all Cold Storage games (the new Halo 3 map) and offers double-XP.  (7/7 – 7/9)  Members of the Bungie team will be playing throughout the weekend so you may encounter one of the Halo 3 developers on the battlefield.

On 7/10, a special “Fiesta Double-XP” weekend kicks off, with Fiesta gametypes (random weapons) offering some unpredictable antics. (7/10 – 7/14).
