DUNE IV

DUNE IV is a sequel to DUNE III, written by the same author. DUNE IV, like DUNE III, is an improved version of "DUNE II" from every angle, and is written entirely from scratch and contains 12 levels per dynasty (for the old Atreides, Ordos, and Harkonnens episodes from DUNE III) and 10 levels per dynasty (for new episodes that are not in Dune III), with the original storylines and maps.
