Here is a very comprehensive walkthrough of Half-Life 2: Episode Two, written especially for PlanetPhillip.Com.
It was made possible by the writing and research of Stanley E. Dunigan and the formatting skills of William Barnard.
Together, we have created a PDF version that can be viewed both online and printed.
(A PDF file is a file that can be viewed directly in modern browsers and downloaded to your computer to be opened by a variety of readers. William recommends Sumatra.
Once I started posting the TREE chapters I thought it might be helpful to add a walkthrough for each chapter. I search the Net and found Stanley’s work to be the best. I contacted him and asked permission use his walkthroughs and he kindly agreed.
For Half-Life 2: Episode Two he kindly agreed to write one from scratch.
