City of the Dead

From publisher blurb:

A remote ghost town in the canyon is stirring with an ominous presence: The long-dead denizens of the town have been resurrected by powerful necromancy, forming a newly risen army. Fight your way through hordes of the undead, explore the abandoned township, and delve into the necromancer’s lair to reverse the spell… Before it’s too late!

City of the Dead was originally written and optimized for a party of Level 10 characters, though is primarily narrative-based and may be adapted to all levels.
