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.
Two playlists and a new game type, "Infinity Rumble," will accompany the pack's release. All three are exclusive (for a limited time) to Majestic Map Pack owners. Infinity Rumble is a free-for-all game type that places a greater priority on acquiring personal ordnance and the conservative use of it. Slower spawn times also reflect the importance of each kill and death. The playlists, Majestic Team DLC and Majestic FFA DLC, feature up to eight players in each, four-vs-four in the former, and free-for-all in the latter.
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.
