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

Valve's Source SDK receives a massive update, granting full access to Team Fortress 2's codebase! This unprecedented move allows modders to create entirely new games based on TF2, going far beyond the limitations of Steam Workshop or simple modifications.

This open-source access empowers creators to extensively modify, expand, and even completely rewrite Team Fortress 2. However, Valve emphasizes a non-commercial clause: any resulting mods or derivative works must be freely distributed and cannot be sold. Despite this restriction, creations can be published on the Steam Store, appearing as distinct entries in the Steam game library.

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

In addition to the TF2 code release, Valve is implementing a substantial update across its back-catalog of Source engine multiplayer titles. This update introduces 64-bit binary support, scalable HUD/UI elements, prediction fixes, and numerous other enhancements for Team Fortress 2, Day of Defeat: Source (DoD:S), Half-Life 2: Deathmatch (HL2:DM), Counter-Strike: Source (CS:S), and Half-Life: Deathmatch: Source (HLDM:S).

This news follows the December release of the seventh and final chapter in the long-running Team Fortress 2 comic series, a testament to Valve's enduring commitment to this classic franchise. The comics have served as a valuable source of lore and character development for dedicated fans.
