Red Alert 2 Chrono Commandos in Campaign is OP
So I completed the Allied Campaign for the first time recently, and I've got to say, once you've figured out how to unlock the Chrono Commando in the campaign, even the hardest difficulty becomes easy.
With enough micro skills, you can have the commando teleport into an enemy base, blow up all of their reactors, construction yard and refineries, and they basically become helpless. I don't think the game was designed for me to be able to do this.
