The first piece of leaked concept art is uncovered via the 2008 “IntoThePixel” 2008 art collection. The piece is titled “Advisor” and is credited to artists Ted Backman, Jeremy Bennett, and Tristan Reidford. The image depicts Gordon in a large Combine-esque structure with a haunting Combine Advisor in above him.

When asked if the increasing development time of Episode Three is being caused by the scope of the project or the result of other projects at Valve, Doug Lombardi claims both. He says “… we want the next installment of Half-Life 2 to be really big.” “So I mean, we’re taking more time because it’s a more ambitious project. We also sort of had Left 4 Dead become this big thing in the middle of it that we wanted to spend more time on, and you’ve just got a lot of stuff that we spent this year doing with Team Fortress 2 updates and what have you. So there’s just a lot going on, and then an ambitious project on top of it caused the schedule to move out a little bit from the delta of the last three releases in the franchise.” This information is extremely interesting in hindsight.
