Coffin Rock

From the back of the 30-page, full-color supplement:

"A Town Sliding into Hell!

The mining town of Coffin Rock, Colorado, is a seething cauldron of trouble.

The local soiled doves are making a killing, some say ghosts walk the streets, and a mad serial killer is on the loose. And there's more, amigo! Lots more. A group of outlaws have hatched a vengeful scheme to get even with the locals, a new preacher is stirring up trouble, and a mysterious shaman foretells dark tidings from the nearby hills.

All that stands between the town and more chaos than a twister in Kansas are a posse of strangers still dusty from the trail. Polish up your six-guns, dust off your Hoyle's, fire up that flamethrower, and get ready for more Weird Western action than you can shake a tomahawk at!

Coffin Rock, better hope it doesn't put you in the ground."
