Mega Man 1 Walkthrough

Recommended stage order
Cut Man - ElecMan - Ice Man - Fire Man - Bomb Man - GutsMan.

Use the Rolling Cutters on ElecMan. Use the Thunder Beam on Ice Man. Use the Ice Slasher on Fire Man. Use the Fire Storm on Bomb Man. Use the Hyper Bomb on GutsMan. Follow these instructions, and you can make quick work of those guys.

Bomb Man Stage: Orb City
Use the Ice Slasher to freeze the Sniper Joes. They should try to open fire, then freeze-up. Blast them. Are those angry looking bullets giving you trouble? Freeze them too. Use this against that little orange orb with the six-way shot later in this stage.

Guts Man Stage: Mountain Mines
The little hard hat robots (Metools) can only be destroyed when he lifts his hat up to fire (when you can see his eyes) Use the same Ice Slasher/Sniper Joe tactic on the hammer-throwing robots in this stage. Watch out for the spikes when you head into the lower levels of this stage.

Cut Man Stage: Abandoned Sawmill
Don't bother trying to blast the flying scissors here. Just try to avoid getting hit. When you approach the big cyclops robot, you're almost at Cut Man's front door. Try running underneath the big robot when he performs a high jump.

Elec Man Stage: Electrical Tower
You must pick-up the magnet beam in ElecMan's stage to beat the game. You will not lose it once it has been collected. The item you'll be looking for resembles a blue light bulb. You should wait on this until you have obtained GutsMan's Super Arm to pick this up.

Use Cut Man's cutters to destroy the flat enemies in ElecMan's level. The Fire Storm and ElecMan's own Thunder beam should work just as well when you return later.

Ice Man Stage: Frozen Jungle
Be careful on the icy surfaces on Ice Man's level. Study the pattern of the holograph blocks carefully.

You can make Mega Man perform a moonwalk on this level! Just run towards the shutter doors leading to Ice Man's lair and hit left before you enter. When the door opens, Mega Man will walk in backwards!

Fire Man Stage: Steel Mill
You can freeze the walls of flame by using Ice Man's weapon. They will turn blue and become harmless. You can even stand on them to jump higher... remember this in Skull Fortress.

Wily 1: Courtyard
Use the Ice Slasher to freeze the jumping cyclopses early on it this stage. Shoot them with your standard blaster until they blow up. Use the Ice Slasher again to freeze the fire walls, but you have to time it right, or else you'll block yourself out.

Do you have the Magnet beam? Try not to use it until you reach the section immediately following the spike pit with the floating platforms. You'll need the extra energy in case you mess up.

Use ElecMan's thunder beam against the Yellow Devil. It can inflict a good amount of damage and works quite well combined with The Glitch.

Wily 2: Rooftop
You will face Cut Man and ElecMan again here. They are no more difficult than they were the first time, so deal with them accordingly. Then you will face a clone of Mega Man at the end of the stage. Use Fire Man's weapon against the fake Mega Man. It seems to do the most damage.

Wily 3: Drainage System
You will face a group of robots encased in big bubbles, one at a time. Use your standard blaster on the first three, then use Gutsman's super arm to pick up the four blocks at the bottom of the screen to quickly destroy the last of them.

Final Wily Stage: Factory
Before you enter the teleporter, you will spot an extra life and another symbol nearby. This new item will replenish all of your weapon energy if you need it refilled. Should you try and grab it, you need to be careful and avoid the spikes below.

You will face Bomb Man, Fire Man, Ice Man and GutsMan again. Deal with them as you did the first time.

Then, it's time for Dr. Wily himself. Attack the ship's weak spot with Fire Man's fire weapon, it should work effectively. Then, when Wily can be seen in the cockpit, hit the dot on the ship with Cut Man's cutters. This works the most. If you're having trouble, use The Glitch!
