Worldbuilder for Command & Conquer 3 Tiberium Wars is the toolset that the game's designers used to create all of the single-player missions and multiplayer maps, and now it's available for everyone to use.
Q: Why is Worldbuilder not included with the shipped version
of Command & Conquer 3?
We made various changes to previous versions of Worldbuilder during development of Command & Conquer 3, which needed to be documented. Furthermore, references to previous projects and old functionality needed to be removed both from the software and the documentation. As a result, we wished to take extra time to best prepare Worldbuilder for its intended audience. Worldbuilder is a fairly small program that references all the artwork and other assets already built into Command & Conquer 3, so we believed that providing the toolset on a download-only basis would not overly inconvenience those looking forward to it.
We are absolutely committed to releasing the latest version of Worldbuilder for Command & Conquer 3 Tiberium Wars in early April, and you will be able to download it right here directly from our site. The Worldbuilder download will include a detailed instruction manual (100-plus pages) that is intended both for beginning map designers as well as advanced and returning Worldbuilder users.
Worldbuilder Lets You Create Multiplayer and Skirmish Maps:
This development toolset is used by Electronic Arts designers to create single-player missions and multiplayer maps for Command & Conquer 3 Tiberium Wars, and it will soon be available to you.
Please Note: This release of Worldbuilder is specifically intended to let you create multiplayer or skirmish maps. While the Worldbuilder toolset and instruction manual will contain features and documentation about how to create single-player campaign maps, Command & Conquer 3 Tiberium Wars is not compatible with user-created single-player campaign content at this time. A separate Mod SDK release for Command & Conquer 3 Tiberium Wars will enable users to create and run their own single-player content for the game. Until you have the Mod SDK for Command & Conquer 3 Tiberium Wars, you may still use Worldbuilder to learn and explore methods for creating single-player content; however, you will not be able to fully test or play this content unless you have the Mod SDK.
