Yes folks, today is officially Bungie Day throughout the world. Celebrate with your Halo lords by fragging a couple friends online in Halo 2 for either the Xbox or PC.

As a special gift, Bungie is putting up some special Bungie Day gamer pictures and a theme for FREE on the Xbox Live Marketplace on the Xbox 360. You read that right… FREE.

Make sure you grab these pretty quick, though. Once midnight hits, these puppies are gone forever. As in never available again. As in pray your Xbox 360 doesn’t die if you enjoy these because you won’t be able to download them again.
