This expansion for Dune introduces 2 new alternative player races, as well as new game mechanics to help you gain advantages over your rivals.                                                    

TLEILAXU:  Led by a small council of Tleilaxu Masters – the fanatic, xenophobic Tleilaxu were tolerated because of their useful genetic engineering superiority. Although underestimated and loathed by others, they hoped to someday dominate all.

IXIAN: The cyborg, Prince Rhombur of House Vernius, leads the Ixians, masters of manufacturing and technologies only they know how to deploy.
