Developer Biography

Marc Laidlaw is the author of half a dozen strange novels, including Dad's Nuke and The 37th Mandala. He is also the person most responsible for making sure the edgy and intense Half-Life storyline worked in the game.

While writing a cover-story about Quake for Wired Magazine, he determined that level designers had the coolest jobs on earth--although the fact that he'd been working as a legal secretary for 10 years might have warped his perceptions very slightly. Oddly, he refuses to do anyone else's typing.

He is currently a Writer/Game Designer with Valve.
