Team Fortress 2 Modders Rejoice as Valve Releases Full Client and Server Game Code

Valve's Source SDK receives a monumental update, granting full access to Team Fortress 2's client and server code. This unprecedented move empowers modders to create entirely new games based on TF2's foundation, going far beyond the limitations of Steam Workshop or standard modding.

This open-source access allows for extensive modification, expansion, and even complete rewrites of Team Fortress 2's mechanics. While commercialization is prohibited – all derived content must be non-commercial and free – creations can be published on the Steam Store as independent games.

Valve's decision acknowledges the significant community contributions to TF2, particularly regarding in-game items created through Steam Workshop. To maintain this respect, Valve requests modders refrain from profiting from the work of Workshop contributors. Ideally, mods would continue to allow players to utilize their existing TF2 inventories.

This expansive update isn't limited to TF2. Valve is also implementing a major upgrade across its back-catalog of multiplayer Source engine titles. This includes the addition of 64-bit binary support, scalable HUD/UI, prediction fixes, and numerous other improvements for Team Fortress 2, DoD:S, HL2:DM, CS:S, and HLDM:S.

This news follows the December release of the seventh and final update to the Team Fortress 2 comic, a series that has spanned seven years and served as a significant source of lore and character development for the game's dedicated fanbase. The conclusion of the comic series underscores Valve's ongoing commitment to one of its longest-running franchises.
