Expansion for Dune that adds two new factions: the Ixians and the Tleilaxu. Tleilaxu: Led by a small council of masters, the fanatical and xenophobic Tleilaxu have been tolerated due to their superior expertise in genetic engineering. Although despised and underestimated by many, they hope to one day dominate the universe. Ixians: Prince Rhombur from House Vernius, a cyborg, is the leader of the Ixians, a people of experts who utilize technologies that no one else knows how to use. Both the Ixians and the Tleilaxu are essential to the economy of CHOAM and the Empire. The royal family of Ix was once the wealthiest in the universe. After the invasion of Ix by the Tleilaxu and the Emperor's Sardaukar, and the subsequent liberation of the planet by the Ixians and Atreides, the Ixians and the Tleilaxu have become bitter enemies. This expansion also introduces new gameplay mechanics that will help you gain an advantage over your rivals.
