Rick Swan reviewed War Against the Chtorr for Dragon magazine #203 (March 1994). 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?" References
