This is one of the robot master stages from my second level pack, Megaman Adventure 2. One of my goals with this set was to work on stage aesthetics and enemy placement. I think all of the robot master stages are very enjoyable - but you will find the difficulty ramp up with the fortress on this one.

Stage Theme: Haunted Forest - Navigate the spooky forest and puzzles to stop Shade Man! From the previous version, this levels combat challenge has been scaled down. I still find it to be the most challenging of the 8 stages though.

Hidden Items: E-tank (Super Arm required)
? Tanks (no weapon required. Rush coil must be used for one though)
Command Select Upgrade (Mirror Buster and Oil Slide required)
