A well presented/structured and in depth explained tutorial covering Vscripts and their usage to script and code/modify various aspects of the Source Engine. It is also the best presented tutorial across all categories. The writing and flow are smooth and allow for easy following even for the folks that aren't very familiar with coding/scripting. This tutorial has great potential since it allows the creation of new gamemodes in the Source engine, at the discretion of the mapper without the need for third party software code.
A well rounded and balanced tutorial covering all the basics that one needs to start compiling and decompiling models.
