There are actually TWO 'Doug Walkers' active in the gaming industry. I am the one that worked at SouthPeak Interactive on titles like Virtual Jigsaw, Looney Tunes Jigsaw, Temujin, Dark Side of the Moon, 20,000 Leagues: The Adventure Continues, and served as lead programmer and co-designer on Wild Wild West: The Steel Assassin. The other Doug Walker worked on Close Combat and other games with Atomic Games.
