In the past, those who have wanted to mess around with the Software Development Kit for Valve’s seminal Source engine have had to purchase a game that uses it. Considering that Half-Life 2 and the Left 4 Dead games are such titles, this probably hasn’t been a problem for most PC gamers. If you’ve been on the fence, though, and wanted to get into Source engine development, Valve has taken money out of the equation. Along with the free-to-play launch of Team Fortress 2, Valve is making the Source SDK freely available to anyone who wants to use it. Though the change won’t be immediate, those who are interested should check out the “Tools” section of their game library and download the SDK. 
Either way, free is free. |
