Actually, I hadn't heard of him either. I'd heard the names of the games, but not the name of the character.
I also edited the title of the thread to reflect GOG's latest sale: 25% off of Ghost Master and Painkiller until Monday the 22nd. Pretty nice! Ghost Master is actually a very cool, underrated, and largely unknown game. I highly recommend checking it out. It's sort of... like The Sims interface laid over a puzzle game that involves taking ghost and monster units and scaring the shit out of people. It's really quite unique.
