Post news Report content RSS feed Source SDK is free

Following the free to play release of TF2, Source SDK has been accidentally released free, and will remain that way.

Posted by INtense! on Jul 4th, 2011

This news comes a little late, but for those unaware due to the recent release of a free Team Fortress 2, the Source SDK will soon become free to use in its entirety, for everyone (confirmed by Valve's Robin Walker in this RockPaperShotgun article). The free SDK was first uncovered in our forums on the 28th of June by an enterprising young man going by the name of Riley, who just happens to be the playtest leader of esteemed Source mods Zombie Panic Source and No More Room In Hell.

This means that all Source mods, made for Valve games (we list around 1,500 for HL2 alone) may eventually be free to play, without requiring you to purchase a Valve game (thou who hasn't purchased a valve game on this site?)

Here is what Robin Walker had to say:

Robin wrote:Yep. That said, your email has triggered a process here that made us re-examine that, and we’re going to just go ahead and make the Source SDK freely available. Thanks for making us better!

When RockPaperShotgun emailed Walker for further confirmation, and he went on to explain:

Robin wrote:We are in the process of getting it all done. It’s a bit messy because we have multiple versions of the SDK, and there’s some dependencies we need to shake out. But yes, the gist of it is that we’re just going to go ahead and make the Source SDK freely available.

Nifty... share this great news!

Maybe once they have made a reasonable amount of money off a game, they release it for free since you most likely are going to download it anyways.

Yeah, all those micro transactions (and some not so micro from the crazies) for hats, weapons, paints, packs, mapper support (which is cool, actually) and all that jazz.

A new engine would explain why Half Life Episode 3 is taking so long.

Think about it HL1 on the Gold Source engine in 1998 and HL2 came out in 2004 on the new Source engine. So its logical given Valves history that Episode 3 will be on a brand new engine.

So think about it how could Valve make a new revolutionary engine that's better than Source and other contemporary engines? Can you? Because I cant really come up with anything and thus I can understand why Valve is taking so long with Episode 3. We know they are working on something since we can see their experimenting with games like Portal 1 & 2 with their new features.

The name's been leaked as HL3, though, so that even further strengthens your argument.

Yeah. It'll be HL3 if it's on a new engine, to keep with tradition and all.

If i'm honest, i think they should use an engine similar to CryEngine 3, it would make HL3 amazing.

That OR:
They're doing massive upgrades to the Source Engine to prepare for a full on Half Life 3.

For example, the graphics of Portal 2 are vastly superior to the graphics in Portal. Also, didn't they say that, for DOTA2, there will be "improved global lighting" and "true cloth simulation" built into the Source Engine?

BUT, then again, only Valve knows what Valve has planned...

Looks to me like they're becoming more of a distributor rather than being a developer. Just my thoughts though.

Valve doesn't really charge for game content, except for tf2 of course. although, everything you can buy, you can just get for free with some patience. they never really demand your money.

Valve never pull crap like that?
Only throwing my 20 euros to the trash. It's not crap. It's AMAZING 'cause it's being wasted by the legendary VALVE.
Don't worry Valve, you are doing the right steps to become ActiValve.
Soon we will pay for DLCs, it will move on to subscription fees, and then we will pay-per-minute for Steam.
Feel free to down this comment, you know it's true.

So because valve is putting all sorts of things out for free and gives free updates that means that soon they will make you pay for everything?

Durr logic error.

Sorry but that makes no ******* sense.

I can hardly even understand your comment to begin with.

??? try looking up review or try it a friends copy of a game before buying it and blaming valve that you don't like it and you can't return it. And why would giving things away free with free updates, cause them to start charging for DLC or sub fees?

"oh no! Valve are giving away a game for free, soon we'll have to pay for DLC!" what????

@Triden007 they still earn more then they can spend, just think about how much money they earn with the Tf2 store and the Portal 2 store (not that i own portal 2, not that i ever will. So i dont know if the stuff in there is free) Think about that, they have no reason to sell Tf2 anymore, because everyone has it. And they'll still earn good on the store.
