TF2 Modding Unleashed: Valve Open-Sources Game Code

Valve unleashes a colossal Source SDK update, granting full access to Team Fortress 2's client and server code. This empowers players to craft entirely new games, surpassing the limitations of Steam Workshop and local modifications. Modders gain unprecedented freedom to alter, expand, and even completely overhaul Team Fortress 2.

While commercialization is prohibited – all creations must remain free and non-commercial – these new games can be published on the Steam Store, appearing as distinct entries in the Steam game library.

Valve's decision acknowledges the significant community investment in TF2 inventories and Steam Workshop contributions. The company requests that mod creators respect this investment, refraining from monetizing efforts built upon the work of Workshop contributors. Ideally, many mods will maintain compatibility with players' existing TF2 inventories.

This update also brings substantial improvements to Valve's back catalog of multiplayer Source engine titles. These enhancements include crucial 64-bit binary support, scalable HUD/UI, prediction fixes, and numerous other refinements across Team Fortress 2, DoD:S, HL2:DM, CS:S, and HLDM:S.

Following a seven-year hiatus, December saw the release of the final chapter in the Team Fortress 2 comic series. These comics served as a valuable resource for fans, revealing new details about beloved characters and storylines, and underscoring Valve's enduring commitment to this long-running franchise.
