Accurate Harkonnen Deathhand
When you play as House Harkonnen, you receive a palace in later levels. This palace contains the Deathhand missile. While extremely powerful, it is also the most highly inaccurate projectile. However, if you put the pointy end of your mouse on the top of a structure's flag when aiming and simultaneously hold down the letter T, this missile will destroy that structure and those around it in a single shot.
Invincible
Required: Atreides, Level 5 or higher, High Tech Facility, Repair Facility.
Build walls around the Repair Facility to block the entering passage, and Build a Carryall with the High Tech Factory. then damage one tank or any vehicle until the damage meter gets yellow, the Carryall transport it to the repair facility, and automaticly put it back. now the tank is invincible, when your unit approach the enemy base, they didn't notice you, by any chase destroy all buildings. only a unit will attack you if you attack him.
NOTE: Invincible is only able with Atreides and level 5 or higher.
Able to stop Enemy Building
While Eliminating the enemy base, first Destroy the Construction Yard. The enemy wouldn’t build anymore after that building is destroyed, the only way to get a new Construction Yard is to build a Mvc (Heavy Factory Required), but the computer never build this object. So no worry and continue you’re attack.
Note: Some levels has two enemy Construction Yards, so it would even possible that buildings can rebuild after destroying the first one.
