Since Halo 3 was updated to 1750 last year many gamers have been stuck at 1500 of a possible 1750. A month ago Halo 3 gamers who bought Halo Wars Limited Edition were given access to the Mythic Map Pack and the last 250 GS.
Finally, the rest of us can achieve those last 250 points when the Mythic map pack release to the general public on April 9th. It will weigh in at 800 points. The pack includes three maps. Assembly is a small map which the developers felt Halo 3 was lacking. Orbital which is a tight-quarters asymmetrical combat map. Sandbox is a large outdoor map with three levels and is intended for Forge modifications.
