The expansion adds new mechanics as well as two houses to the game: Ixian and Tleilaxu. House Ixian is led by the cyborg Prince Rhombur of House Vernius, and they are experts in manufacturing and technologies. The royal family of Ix was one of the wealthiest families in the Imperium until they were invaded by Tleilaxu, and then, later freed with the help of the Atreides.
The second house added in this expansion are the Tleilaxu, who are masters of genetic engineering. They are the Emperor's allies, but they are power hungry and plan to dominate the CHOAM. The Tleilaxu are also mortal enemies of the Ixians, and still seek to impose their will on them.
Dune: Ixians & Tleilaxu House Expansion will retail for $20.00.
