Aliens: Phalanx

Ataegina was an isolated world of medieval castles and rich cultures—vibrant until the demons rose and slaughtered ninety percent of the planet's population. Swarms of lethal creatures with black husks, murderous claws, barbed tails and dreaded "tooth-tongues" rage across the land. Terrified survivors hide in ruined mountain keeps, where they eke out a meager existence. Skilled runners travel the treacherous paths between keeps, maintaining trade and sharing information. If caught, they die screaming. Ahiliyah of Lemeth Hold is an exceptional runner, constantly risking her life for her people. When she and her closest companions discover a new weapon, it may offer the one last chance to end the demon plague. But to save humanity, the trio must fight their way to the tunnels of Black Smoke Mountain—the lair of the mythical Demon Mother.
