Bungie have followed up on their promises and released a seven-minute documentary showing a few Halo 3 features.

Xbox Live has the documentary in both standard (480p, 97MB) and hi-def (720p, 336MB). It’ll be coming to the rest of the interwebs later today.

The documentary discusses Brutes and shows off a couple of new weapons, it even lets you see a bit of the single-player campaign. Apparently a lot of the graphics are from a fairly old point in the stage of development so aren’t entirely representative of what you should see in the final product.

If you’d like to read a bit more on the doc then head over to the Bungie site and check out what Frank O’ Connor has to say. To see the trailer itself, turn on your 360, or head round to your Xbox-owning friend’s house.
