As Halo fans will no doubt be aware, today is Bungie Day or 7/7 and marks the release of a new Halo 3 multiplayer map called Cold Storage, inspired by the original map Chill Out from Halo: Combat Evolved.

Gamers will also be able to download seven exclusive gamer pics and a Bungie Xbox 360 dashboard theme available for free on Xbox Live Marketplace. These items will only be available for today so make sure you don’t miss out. Today also sees the Halo 3 Legendary Map Pack dropping to 600 Microsoft Points.

The number 7 has always played a significant role in Bungie games and this significance eventually gave rise to Bungie treating fans to new content or a free download on 7/7. To see how many references there are to the number 7 in the Halo universe head over to the Halo wiki.
