Bungie and Microsoft have unveiled Blackout as the last of three maps to be included in Halo 3's forthcoming Legendary Map Pack. A true to the original remake of the Halo 2 fan favorite Lockdown, Blackout is a fairly large map that features an abundance of interconnected platforms and walkways.
The Legendary Map Pack hits the Live Marketplace next month on April 15 for 800 Microsoft Points. Oh, and don't forget that the Heroic Map Pack is now free.
