HL SDK Intro

Okay, the HL SDK is a Development Kit, you can do all kinds of things with this, for example, create a modification for Half Life is one of the things, or you can look at the brief tutorial of making game models. You can use the default tools the HL SDK has provided to start working to create a modification, the sprite tool ( in SDK\Sprite Tools )... and also, the out-dated and not recommended Worldcraft aka Valve Hammer Editor to create maps, you might want to use different compiler tools and a different Hammer Editor(Download here) and for the tools I recommend ZHLT, Zoners Half Life Tools(Download here).
