An update yesterday marks Season 8 for Halo: The Master Chief Collection, a collection of six games in the Halo franchise. This update is a big one for modders, as it provides official modding support for Halo 2 and Halo 3

In yesterday afternoon's update on Steam, the original Halo got an update to its modding tools. However, the bigger news concerns the game's sequels, as Halo 2 and Halo 3 got modding tools of their own. Players will need to own a license for the base games in order to gain access to the modding tools, but anyone who buys Halo: The Master Chief Collection will have both games already in their library. If you do, you can either download the modding tools as standalone DLC, or find these tools by in your Steam Library under "Tools."

The following tools, which consist of some familiar ones and some new ones, are available for modding Halo 2 and Halo 3:

  • Guerilla: Lets users update and alter the values of game content, collectively known as "tags."
  • Sapien: The world/level editor for the game.
  • Tool: A "command-line-only Swiss Army knife" that lets users perform tasks related to "importing source content into tag files or even to building map files."
  • Standalone" This brand-new program is essentially a development build of the game itself, which runs off tag files instead of cache files. It's aimed for more advanced modders and can't be used for multiplayer-based modding. Don't expect the fancy bells and whistles with this tool; this tool is very "what you see is what you get." 

In addition to these tools, users will also have access to zip files of level scripts and all of the tag files that go into building the campaign and multiplayer levels.

Halo: The Master Chief Collection is available on Steam, Xbox One, and Xbox Series X|S.
