Age of Empires 2 HD custom campaign: Catastrophe cavern-Chapter III (final part)

Finally, we did it! Third chapter is over after hours of gameplay. We have defeated all of our enemies, and only thing that was left was the relic. But, we had to mine the way to it. And then of course to wait 400 years to win with a relic victory. Unfortunately we did the opposite thing: in the first place we have defeated the guardian and then after we defeated all of our enemies we took the relic. After this one we are going to the chapter IV. So, let us see how this chapter went!
