"The first batch of new, downloadable Halo 2 multiplayer maps will be available on Monday April 25th for download on Xbox Live. Woot! The maps passed through Microsoft's certification process successfully today, which was all we were waiting for! We said we'd tell you as soon as we could, and we found out about an hour ago that they'd passed with flying colors. The Bonus Pack - comprised of Containment and Warlock, is free. Log into Xbox Live, go to the download content menu item and get 'em. The Killtacular Pack, comprised of Turf and Sanctuary, is $5.99 US (local prices will vary by country) but for the patient, it too will be available for free on June 28 th . The maps will be available in custom games immediately, and in Matchmaking some time soon after. We'll bring you news on the Matchmaking playlists update shortly. "
