The Blastacular Pack is a downloadable content package for Halo 2. It added two new maps to Halo 2: Desolation and Tombstone. It was released on April 17, 2007 for $4.00, and re-released as an updated package on May 7, 2007, as several glitches discovered in the included content had been fixed. The Blastacular Pack was made permanently free on July 7, 2007. This download was required in order to play Halo 2 Matchmaking over Xbox Live. Both maps in the map pack were created by the video game studio Certain Affinity instead of Bungie. Due to the pack's release in 2007, it is not included in either the Halo 2 Multiplayer Map Pack or the PC port of Halo 2, making the content now unattainable for the original Halo 2 game. However, it is included in the release of Halo: The Master Chief Collection.
