Today is 'Bungie Day' according to, well... Bungie. So to mark the occasion it has released a new multiplayer map for Halo 3.
Titled Cold Storage, the new map is a shiny remake of Halo 1 favourite Chill Out - a small map great for one-on-one skirmishes and you can download it for free.
Browse around XBL today and you'll also find new gamer pics and a Bungie Day dashboard theme, too. And the Halo 3 Legendary map pack has dropped in price down to 600 MS points (just over £5).
