The Blastacular Pack is a downloadable content package for Halo 2. It was released on April 17, 2007 for $4.00, and re-released as an updated package on May 7, 2007 (still for $4.00), as several glitches discovered in the included content had been fixed. Blastacular Pack was made permanently free on July 7, 2007 (Bungie Day). 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.
The Blastacular Pack added the following new content to Halo 2:
- The Blastacular Pack takes up 142 MB on the Xbox's HDD.
- The Blastacular Pack content is not included in the Halo 2 Multiplayer Map Pack or the PC version of Halo 2, due to this it is the only Halo 2 DLC map pack no longer available without modding on the original Xbox. Though the maps returned in the base game of Halo: The Master Chief Collection on Xbox One.
