Prior to that, I was a writer/designer on the Tom Clancy games at Ubisoft (the Ghost Recon and Rainbow Six series). I have experience writing dialogue, creating storylines, casting and directing voice actors, writing and directing cinematic sequences, and designing gameplay.

I'm also a horror writer, with work appearing in publications like Night To Dawn, Lullaby Hearse, Blackwater Review, and Nanobison. I wrote a comic book called Monster Madness (based on the video game of the same name), which was published by Dark Horse Comics. I'm also a writer/designer of tabletop role-playing games, including Dread: The First Book of Pandemonium and Retrograde.

My column, Screen/Play, is a regular feature at Gamasutra.com, and my articles on game writing have been featured in Writer's Digest, Game Writers Quarterly, and GameDev.net. I'm also the author of The Game Writing Handbook, which was a finalist for the 2007 Game Developer Front Line Awards. I've lectured at numerous industry events, including the 2006 Game Writers Conference and the 2007 Russian Game Developers Conference (where I taught the six-hour master class).
