Ornithopters are the only airborne defence available in the game. Both Atreides and Ordos have use of these flapping machines. Their demonstration in the opening sequence appears far more ruthless than within the actual game, where they rarely make any positive effect at all.
The Raider Spy
An Ordos Raider trike boldly goes into the Harkonnen base to check the location of enemy buildings. Other areas of the map have already been revealed. Unfortunately, level 9 is a little predictable for all houses as the layout of each base is almost identical with Saudukar taking centre stage. At this level avoid building Ordos Palaces as these only produce weak Saboteurs, capable of getting killed quicker than an Ornithopter or, at most, destroying a wall.
Enclosed Repair Facility
See how to enclose your Repair Facility in order to make the Carryalls to the hard work for you. Once you have sealed off this building Carryalls will ferry your damaged units from the battle scene and then return to their initial position.
