Costing 800 Microsoft Points, the Mythic Map Pack also stuffs more achievements into Halo 3's extensive list. The maps included with the pack are Orbital, Assembly and Forerunner.
They're described as follows:
Investigate Orbital's abandoned hallways - before it was evacuated, the Quito Space Tether was heralded as the "Civil Engineering Monument of the Millennium."
Witness Assembly, where Scarab hulls loom overhead, being decontaminated in preparation for the city-sized Lekgolo colonies that will breathe life into the massive metal husks.
An excavation site surrounded by deadly Forerunner defences, the mysteries of Sandbox are hidden high above, deep below, and right before your eyes.
Will you be snapping up the Mythic Map Pack? And do you think it will be enough to put Halo 3 on top of the Live Activity charts over World at War?
