Valve unleashes a colossal Source SDK update, gifting modders complete access to Team Fortress 2's client and server code. This unprecedented move allows for the creation of entirely new games built upon TF2's foundation. Unlike previous Steam Workshop limitations, modders gain the freedom to modify, expand, and even fundamentally rewrite aspects of 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 within Steam's game library.
Valve's rationale, detailed in a blog post, acknowledges the significant community investment in TF2 inventories and Steam Workshop contributions. The company respectfully requests that mod creators refrain from profiting from the community's work, ideally allowing players to retain access to their existing TF2 inventories where feasible.
This expansive update isn't limited to TF2. Valve is simultaneously rolling out a major upgrade across its back-catalog of multiplayer Source engine titles. This includes the crucial addition of 64-bit binary support, improved scalability for HUD/UI elements, prediction fixes, and numerous other enhancements benefiting TF2, DoD:S, HL2:DM, CS:S, and HLDM:S.
This news arrives following the December release of the seventh and final chapter of the Team Fortress 2 comic, a seven-year project that served as a testament to Valve's enduring commitment to this long-running franchise and a valuable source of lore for dedicated fans.
