Cut by late 2003, the Heretic leader escapes the gas mine, and is pursued by the Arbiter on Basis, moon of Threshold and debris site of the first Halo. Journey through a graveyard of remnants from the first ring on a mission blessed by the Noble Prophet of Truth. This release represents an effort to rebuild content originally designed for a different functioning game engine, the second campaign collaboration between Digsite and Halo Studios.

A full, modded Campaign that tweaks the sandbox to make a more gratifying and decision-based game, where every piece of that sandbox has a distinct role. As well as adjusting Legendary difficulty to be less frustrating, but more fair while still challenging.

Project Cartographer is a modification for Halo 2 that restores online play and adds additional features that are not present in the base game.

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.

The Maptacular Pack is the third downloadable content package for Halo 2. It added five new maps to Halo 2: Backwash, Elongation, Gemini, Relic, and Terminal. It was initially intended to release alongside the Halo 2 Multiplayer Map Pack on June 28, 2005, before eventually being released for download on July 5, 2005 for $11.99 and was made permanently free on August 30, 2005. Once the pack was made free, this download was required in order to play Halo 2 Matchmaking over Xbox Live. The Maptacular maps were included in the later releases of the Halo 2 Multiplayer Map Pack, the Halo 2 PC port and Halo: The Master Chief Collection. The Maptacular Pack was originally the final piece of DLC intended for Halo 2, though a fourth - the Blastacular Pack - was later released in early 2007.

The Bonus Map Pack was the first downloadable content package for Halo 2, released on April 25, 2005 alongside the Killtacular Pack. It added two new maps to Halo 2: Containment and Warlock. The pack was released as a free download sponsored by Mountain Dew, and was required in order to play Halo 2 Matchmaking over Xbox Live before its shutdown in 2010. The map pack was later included in the releases of the Halo 2 Multiplayer Map Pack, Halo 2 PC port and Halo: The Master Chief Collection.

The Killtacular Pack is the second downloadable content package released for Halo 2. It added two new maps to Halo 2: Sanctuary and Turf. It was released alongside the Bonus Pack on April 25, 2005 for $4.99 and was made permanently free on June 28, 2005. Upon release, a "deluxe" playlist was created in Halo 2 to allow players to play the Killtacular pack maps, though the download was required in order to play Halo 2 ordinary matchmaking over Xbox Live following the pack becoming free - before the shutdown of Halo 2 matchmaking in 2010. The Killtacular Pack was later included in the releases of the Halo 2 Multiplayer Map Pack, the Halo 2 PC port and Halo: The Master Chief Collection.
