Hint: Create space in your silos:
If you have a starport, you can create more room in your silos for money. Go to your starport and start selecting items to be ordered (specifically ones that are the most expensive). Select as many as possible. Then, when it automatically takes money away, cancel the selections and it will give you your money back, but will not fill your silos again.

Hint: Easy victory:
Do not attack the enemy, let them come to you. When you start, do not build Weapon Factories. Instead, build Cannons and Missile Turrets. It is a good idea to build Trikes and Quads to act as scout lookouts. Try not to build too fast or you will run out of money when they attack. The most important thing is to not put all of your defenses in one place.

Hint: Using Fremen:
On the Atreides missions where Fremen are available, send about six Fremen at a time to cover areas of prime targets. Have them stay still until enemy defenses are low. Fremen are hard to spot when they stay still, so you can build massive attack squads.
