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

Surprise! Valve’s just released a massive update to the Source SDK, adding “all” the Team Fortress 2 client and server game code.

Valve said the update lets players build entirely new games from its source code, and unlike Steam Workshop or local content mods, it gives modders access to change, extend, and even rewrite Team Fortress in pretty much any way imaginable.

You won’t be able to sell anything you make with it — which means any mods or spin-off content will have to be released for free on a non-commercial basis — but creations can be published on the Steam Store, “appearing as new games in the Steam game list.”

“Players have a lot of investment in their TF2 inventories, and Steam Workshop contributors have created a lot of that content,” Valve explained via a blog post. “The majority of items in the game now are thanks to the hard work of the TF2 community.

“To respect that, we’re asking TF2 mod makers continue to respect that connection, and to not make mods that have the purpose of trying to profit off Workshop contributors’ efforts. We’re hoping that many mods will continue to allow players access their TF2 inventory, if this makes sense for the mod.”

Valve also added that it was making “a big update” to all its multiplayer back-catalog Source engine titles, too, adding 64-bit binary support, scalable HUD/UI, prediction fixes, and “a lot of other improvements” to not only TF2, but also DoD:S, HL2:DM, CS:S, and HLDM:S.

Back in December, after seven long years, The Team Fortress 2 comic released its seventh and final update. The comics have not only been a great place for fans to uncover new information about their favorite characters and stories, but they’re also a testament to Valve’s own continuing interest in one of its oldest series.
