A poorly kept secret since November is official now: the Majestic Map Pack, the latest series of multiplayer maps in Halo 4, will indeed be available on Feb. 25 for 800 Microsoft Points ($10).
The maps, consistent with a leak earlier this weekend, are Landfall, Monolith and Skyline (above). Longer descriptions may be seen here, but Landfall is recommended for Infinity Slayer matches; Monolith is best paired with Capture the Flag, and Skyline is suited for Regicide.
According to the original leak back in November, the third map pack, “Castle” will release on April 1. More screenshots of Majestic are available here.
