The map pack bonanza continues!  Not to be outdone by Unreal Tournament 3, Call of Duty 3, or Gears of War 2, Halo 3‘s Mythic Map Pack preps for an April 9th arrival on Xbox Live.

Previously available only as a limited edition Halo Wars bonus, the Mythic pack is priced at 800 credits, and includes three new maps: Sandbox, Orbital, and Assembly.  The Sandbox map includes the new and hotly debated deployable killball, which sounds just Coscarelli enough to be fun.
