Valve just released the entirety of the Team Fortress 2 client and server source code, and it wasn’t even an accident. In a post on the Team Fortress website titled “The TF2 SDK has arrived!” Valve addresses mod creators directly.

“We’ve just released a massive update to the Source SDK, adding all the Team Fortress 2 client and server game code.

Team Fortress 2 is 18 years old now, long past the point most player counts have dwindled to nothing, yet its fan base continues to be as loyal as ever. Part of that is due to Valve’s continued support of the game, fixing bugs 17 years after the game launched.

Valve acknowledges the community’s part in keeping the game alive. “The majority of items in the game now are thanks to the hard work of the TF2 community,” its post says.

With the full source code in hand, the community can keep the Team Fortress 2 going for years to come and potentially
