This walkthrough shows all E-tank locationsand Boss weaknesses. I tried to be as creative as possible with the various weapons without wasting to much time, and I think I succeded. I was a bit sloppy at times, the boss rush was especially shameful, but overall it turned out great.
In terms of difficulty, this scores pretty high, even for a Mega Man. The bossfights are somewhere between normal and hard in Mega Man 10 terms. If you're not good at Mega Man and you're just trying to enjoy the 8-bit remixed music, then you might get frustrated a little.
