A tall tower, with Elecman at the top. Mega Man periodically has to deal with vertically flying objects that fire dual electric blasts at him.
If you have trouble with the spines, switch to another weapon to destroy them; however, remember to keep enough ammo for the Rolling Cutter for Elec Man.
On the second upward climb, you can go either left or right. The left route contains spines, and the right contains some periodic lightning generators; however, the right path requires a bit more of a detour. The Magnet Beam is located halfway through the level. To collect it, you need to defeat Guts Man first.
After the Magnet Beam, you can go to the left or right. The left climb has spines and five electric traps. The right climb only has three electric traps, but requires using the magnet beam you picked up earlier.
Elecman is possibly the most difficult Robot Master; he moves very quickly, and his Thunder Beams are very difficult to dodge. However, he is vulnerable to the Rolling Cutter.
