@Canageek Not directly, but Dark Conspiracy (1991) has Slithers as beasties, and it's very much a "find monsters and unload a wall of guns into them" game. I used Slithers anytime players went into desert wastelands.
You can get all of 1E (better horror flavor, but a little wonky) or 2E (duller, more complex, but more balanced) on CD-ROMs at

The Mike Stackpole novels are *AMAZING*.
