TF2 Modders, Y’all Eating Good—Valve Just Dropped the Full Client and Server Code!

Published on February 21, 2025

Oh my God, y’all are NOT ready for this. No, like, I swear to God, come here now now. Valve just pulled the most insane move and dropped all the Team Fortress 2 client and server game code into the Source SDK. ALL OF IT. Every last bit. Like, this ain’t your basic Steam Workshop modding—nah, you can literally rewrite TF2 from the ground up. What in the actual hell.

Modders, It’s Your Time to Shine

Okay, so picture this: You’re sitting there, playing TF2, thinking, “Man, I wish I could just, like, change everything.” Boom. Now you can. Want to make TF2 but everyone’s a sentient sandwich? Go for it. Want to give the Scout jetpacks? Do it. Want to make Heavy do the Macarena while reloading his minigun? Brother, the power is yours.

And the best part? Whatever you make shows up as a full-blown game in the Steam Store. Like, not just some little add-on—actual games. Oh, and before y’all get any bright ideas: No, you can’t sell ‘em. Gotta be free. Non-commercial. Capitalism is taking a backseat on this one.

Respect the Hats, Respect the Grind

Now, before you start coding your “Pay-To-Win TF2 Battle Royale” (which, honestly, someone’s probably already doing), Valve’s got some words: Don’t mess with people’s hats. TF2 inventories are sacred. Workshop creators poured years of blood, sweat, and Gibus tears into this game, and Valve is basically saying, “Hey, be cool.”

Translation: If your mod tries to sidestep Workshop contributions and profit off ‘em? Not cool. But if you wanna make something wild while still letting people flex their 2007 Unusual hats? Valve’s giving a thumbs-up.

Oh, and They Updated Like… Everything Else Too?

Oh yeah, did I mention? This isn’t just a TF2 thing. Valve went full ham and rolled out a massive update for their entire Source multiplayer back-catalog. I’m talking:
64-bit binary support (modern tech gang, rise up)
Scalable HUD/UI (no more suffering on ultrawide monitors)
Prediction fixes (no more blaming lag, you just missed)
And a ton of other tweaks for TF2, DoD:S, HL2:DM, CS:S, HLDM:S—basically, old Source games just got a facelift.

TF2 Is Still Alive and Kicking, Somehow

Let’s be real—people have been saying TF2 is dead for like, a decade now. Then Valve goes and does this and suddenly we’re in the middle of a TF2 renaissance. Comics finished their saga back in December after seven freaking years, and now they’re just casually handing the game code to the modding community like some kind of fever dream.

Honestly? If TF2’s ever gonna die, it’s gonna take all of us down with it.

Now go forth, modders. Make something insane.
