Just to inform all of you about what the SDK is and what it can do.
Valve will not be releasing a Miracle here, the SDK will be just like all previous SDKs. They will release hammer editor, model viewer, and possibly the faceposer for L4D. THERE WILL BE NO SOURCE CODE, Valve only releases source code for HL2 and HL2MP.
Portal and TF2 were prime examples of what we will get for L4D. No source code, so no major game changing mods.
Also the SDK or Authoring Tools will not be released on Tuesday, it is coming SHORTLY after the release of the Survival pack DLC.
If you have any questions regarding the SDK, post them here, any topics on Tuesday asking where the SDK is will be locked and possibly removed.
Thanks for your time,
L4DMods Staff.
