Team Fortress 2 full code is now available for modding

Modders are the unsung heroes of the gaming industry. Without them, genres like MOBAs (born from RTS mods like StarCraft and Warcraft III), auto battlers (evolving directly from MOBAs like Dota 2), and even the wildly popular Battle Royale genre (thanks to an ARMA 2 mod) wouldn't exist. That's why Valve's recent announcement is so significant.

Valve has updated its Source SDK, incorporating the complete Team Fortress 2 codebase. This empowers modders to build upon a robust, established foundation, creating entirely new games. While the license mandates that these creations remain free, history shows that successful, popular mods often evolve into commercially viable projects.

This update also brings significant improvements to all Source engine multiplayer games. These include support for 64-bit executables, a scalable UI and HUD, crucial fixes for client-side prediction issues, and numerous other enhancements.

It's a monumental day for the modding community, and we eagerly anticipate the innovative and groundbreaking games that will undoubtedly emerge from this opportunity.
