Valve has just unveiled a groundbreaking update to the Source SDK, integrating "all" the Team Fortress 2 client and server game code. This monumental update empowers players to create entirely new games from scratch using the source code. Unlike modifications through the Steam Workshop or local content, this update grants modders unprecedented freedom to alter, expand, and even completely rewrite Team Fortress 2 in virtually any conceivable way.
However, it's important to note that any creations made with this new tool must be released for free and on a non-commercial basis. Despite this restriction, these new games can be published directly on the Steam Store, where they will appear as fresh entries in the Steam game list.
Valve emphasized the community's significant contribution to Team Fortress 2 through the Steam Workshop, stating, "Players have a lot of investment in their TF2 inventories, and Steam Workshop contributors have created a lot of that content. The majority of items in the game now are thanks to the hard work of the TF2 community." They encouraged mod makers to respect this community effort and avoid creating mods aimed at profiting from the Workshop contributors' work. Valve also expressed a hope that many mods would continue to allow players to access their existing TF2 inventories, where appropriate.
In addition to the Source SDK update, Valve announced a comprehensive update to all its multiplayer back-catalog titles running on the Source engine. This includes enhancements such as 64-bit binary support, scalable HUD/UI, prediction fixes, and numerous other improvements, benefiting not only Team Fortress 2 but also Day of Defeat: Source, Half-Life 2: Deathmatch, Counter-Strike: Source, and Half-Life Deathmatch: Source.
This update follows the release of the seventh and final installment of the Team Fortress 2 comic series back in December, after a seven-year wait. The comics have not only provided fans with deeper insights into their beloved characters and storylines but also underscored Valve's ongoing commitment to one of its most iconic franchises.
