The Source engine is a 3D game engine developed by Valve Corporation. Its unique features include a large degree of modularity and flexibility, an artist-driven, shader-based renderer, accurate lip sync and facial expression technology, and a powerful, efficient and completely network-enabled physics system.

Report article 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!

I think the HL (Ep)3 will be the last VALVe game, that i buy (If it's rlease ever). I bought the L4D Now if you had the L4D2, you had the L4D. I bought the Orange box. Now the TF2 is free. (Oh, i'm a premium user, what a wonderful feeling) And now the SDK... Gabe, don't you wana give me the VALVe?

Unless you're unfortunate, you probably bought the OB a looong time ago like I did. Stop complaining. Chances are they will never ever make their single player games free (Portal was an exception and a promotion for Portal 2), just the multiplayer ones. So calm down kiddo.

2: "we are customer of VALVe. But why They give Many things for Many People for FREE" what wrong with them promoting their games by making things free? It helps give new players a high opinion of valve which will give them even more customers in the future.

3: "Please do something for your customers" .............. urrrrr, free DLC???????????

Valve DID do something for their customers.

1. You didn't pay that much for TF2 probably.

2. You have a PREMIUM user now for buying it.

3. They made an awesome game free so everyone without enough money or not wanting to buy it (like me) can enjoy it.

I appologize. You must feel so inferior for buying something when it was new. I bought it when it was new too. I enjoyed it. I still enjoy it. Now people who didn't buy it when it was less than 5 years old can enjoy it too. Honestly, I don't get why people are ****** at valve for making things free. Had you known 5 years ago when you bought Team Fortress, can you honestly say you'd have waited until now to buy it? If not, your argument is voided.

This makes playing mods easier and benefits the modding community. It in no way harms any of their existing customers and follows Valve's tradition to make games affordable with free weekends, special holiday/etc deals, and you could get the source sdk with HL2:DM which has been $5 for a very long time. I honestly can't see any reason anyone would complain but instead I see plenty of reason to once again cheer Valve on for their incredible support of their fans/customers/community. I'm more excited for the new Tools than the updated/new engine that's been rumored.

Also, nice work Riley. I know you don't like praise but you've got great work ethic and have proven to be an asset not only to us at ZPS for so many years but now NMRiH and the entire Source community. Cheers!

I get the feeling a big-hub-a-bub will gone for a while about this.

Frankly, it doesn't matter to me, as I already have the Orange Box.

Just glad modders finally get to make stand-alone games, granted they're based on 2007 Source (2009, I believe, will not be available without Episode 2).

It's just perfect if you ask me.

It's funny because Source is quite possibly one of the greatest engines in the world. Just like Unreal, one of the most widely used, so easy to use and modify and it has probably some of the best physics there is alongside GeoMod and so on.

Okay, so I'm a little late to the comments, but what? Does no one remember Alien Swarm? Alien Swarm is free, moddable, and based on Source. I'm not sure if it was exactly Source SDK, but it would end up being pretty darn close and I know it allowed for total conversions and whatnot.

So this isn't really that huge?

Wow, it's hard not to laugh at all the Valve bashing lately.

"Valve sucks, because I bought TF2 and now it's free!"

"Valve is greedy, because they have an optional hat shop!"

"Valve is being really stupid, and is about to sell all their stuff!"

"Valve hasn't done anything greedy that I can remember, so I'm sure they're about to...Really soon now...I can feel it..."

Lol. Anyway, this is pretty cool, and perhaps it will allow for standalone indie games at some point? That would be pretty awesome. Hmm...I should learn hammer one of these days :P
