Red Alert 3 - Rising Sun Mission 7 Yokohama - Hard Difficulty - Yuriko Only! 

Beating this entire mission on hard, using ONLY Yuriko Omega. (Note that I can't control what my co-commander does, so unavoidably, some of his units helped during some parts of the mission.)
You might remember, I did this back in 2010 ( • Red Alert 3 Rising Sun... ). But here's it done again faster, better, and in HD!
--------
