Dune 2000 - Ordos - Mission 7 - Having Allies and Demonstrating the Sardaukar HD
Mission 7 for the Ordos has something interesting that I really liked about the the factions campaign - the ability to play with Allied forces not specifically under your control. Periodically they amass forces and muster up an attack force to strike forth against the enemy. Eventually into the mission I happen upon the Imperial Palace in the campaign as well. After capturing it, I gain the ability to produce the Sardukar infantry units normally only available to the Emperor. These powerful units do excellent damage on all they attack, though they are still weak like other infantry units so care needs to be taken.
