Microsoft has released a new trailer depicting the heroic Master Chief in the upcoming Halo 4. The latest title will see the Chief battling some new foes, including what seems to be the "Forerunner" foe.

Currently in development by 343 Studios, Halo 4's Master Chief returns to battle an ancient evil bent on vengeance and annihilation. Shipwrecked on a mysterious world, Master Chief is faced with new enemies and a powerful new Forerunner menace.

Microsoft has also revealed the War Games Map Pass, which will allow those who purchase it the chance to experience all the post-content released without the need of buying them separately. The pass is available now for $33.50 (2,000 Microsoft Points) and will give access to three War Games map packs as they become available in December, February and April. Purchasers will also receive two bonus in-game helmets, plus a unique in-game emblem.

Check it out the trailer below for a glimpse of the in-game action, which is quite impressive for the current-gen console. Halo 4 will be available on November 6th only for Xbox 360.
