One of the things that’s a little upsetting about the Half-Life story is that you’re pretty much in the dark about what’s been going on between the two games. And even if you knew that, you’d be missing the big picture story. What’s the G-Man’s motivation? Who the hell is he, anyhow? What’s the relationship between the Combine and Xen? Well, someone’s mixed everything we’ve been told or shown with a little creative speculation, and come up with the Half-Life Saga Story Guide. Amazing.
