This is one of the WILY stagess from my second level pack, Megaman Adventure 2. Prior to the final version, all of the fortress stages were in need of improvements because I had grown to dislike them for different reasons. That is no longer the case. I think I have fixed these stages tremendously and they are a good challenge given your strong arsenal.

Stage Theme: Wily 3 (Simulation Lab) - This is my favorite stage from the Wily set. You will find a capsule room with four capsules that must be completed. Each one contains two bosses at the end of about 4-5 room segment, which drop a key. For me, I got a chance to creatively combine mechanics from the stages. However, I can see how the bosses may be difficult - so don't forget to use your weapons! Additionally, one MM Adventure 1 boss can be found to unlock a power to help you.

Hidden Items: E-tank (No weapon required - found within the Fire Route)
