Black Widow Games is run by Neil Manke. If anyone played USS Darkstar from PC Gamer or any of the They Hunger series years ago, that was all Neil. He is the premiere HL sp mod maker, and now he's releasing a commercial title in the They Hunger series. Check it out. Even if you don't like HL, check it out.
