From the Publisher The town of Cripple Creek (DS 3) is suffering from small quakes or tremors. Sheriff Bruno O'Malley is looking for a stout group of wastelanders to go and investigate the disturbances, which he believes are from the old mines of the Nevada Mountains that overshadow the town. Tremors is an Exodus OPS campaign scenario for 4 to 6 characters of 1st to 5th level, and can be easily adapted to any other Post-Apocalyptic setting.
