Red Alert 2: Mental Omega (Allies Mission 12) [Defending Fortress Britain] 

Finally a mission I used good tactics to fight off the A.I's constant attacks. And used all the tech available in the mission to make the job easier.
This is a fan-made enhancement of Red Alert 2, which adds more units, missions and an alternative story-line to Red Alert 2. Big thanks to the creators of this mod! Using the hardest difficulty settings.
