GURPS War Against the Chtorr is a sourcebook for the GURPS role-playing game.

Publication history[edit]

War Against the Chtorr was designed by C. J. Carella, and published by Steve Jackson Games.[1] The book was published in 1993.


Rick Swan reviewed War Against the Chtorr for Dragon magazine #203 (March 1994).[1] Swan comments: "Intelligent worms the size of mini-vans invade the Earth in this first-rate supplement for the GURPS game. Based on the David Gerrold novels, War Against the Chtorr serves up all the raw material a malevolent referee needs to wipe out the human race; when the PCs think they've got a handle on the worms, see how they fare against nerve-burners, jellypigs, and pipe-cleaner bugs. Are you squirming yet?"[1]
