Mega Man 4 Walkthrough

Toad Man's Stage: Rainy Sewers
From the start, head right, defeating the Umbrella Guards (umbrella holders) and the Rocket Birds (swallows and babies), carefully jumping over the pits, and jump into the sewers. Inside the Rainy Sewers, drop down and defeat Toad Man. He will do his own "hula dance" to do Rain Flush. Shoot him. He will either jump over you or do his hula dance again.

Pharaoh Man's Stage: Egyptian Excavation
Uh-oh! You're in a large quicksand and Sasoreenus are popping out! Do not hit the one on the left as the sand will sink you and fight through more enemies and enter a pyramid! Kill off the Mummiras and the Hovers and do not touch the spikes. Now enter deeply and shine your light on Pharaoh Man! Kill him with the brighter lights until you win the Pharaoh Shot.

Ring Man's Stage: Space Simulator
Slide across the 'rainbow',Jump and shoot the cannon(it can only shoot at 3 different angles) and climb the ladder. get the next 2 canons and jump on the middle of the next 2 rainbows, climbing the ladder again. Next, 2 planets that both look like saturn and move like the Telys from mega man 2 come floating towards you (the good thing is that their HP is only 1, so no need to worry). Shoot them and continue on. The next screen is a chalenge, 2 cannons high above you, and sevral short rainbows in between(did i mention that these disappear? i don't think so). slide across the rainbows, and get the cannon out of your way. climb another ladder and continue on. now cross this next rainbow and prepare to get 'gamers thumb'. its... a giant hippo?! anyways, shoot the blocks its standing on to lower it, so you can shoot it more easly, but the blocks regenerate, and the hippo will spit homing misles at you. get rid of it and move on. Ignore the new type of Spines below the rainbows, shoot the planets, and-oh no! there's a pair of rainbows above some spikes! anyways, jump as far away from the begining of the rainbow as you can, and slide the rest of the way over. jump down the pit and another sub-boss is waiting for you. its a bunch of rings with closed eyes. WTF? so, if have Bright man's weapon, use it as soon as the rings shoot outwards, and give him heck! When he dies, the thing he was standing on blows up. drop down, but dont charge your buster, you wont need to. Why? because it's another @$^%#@# giant hippo!!* so just use the same strategy as before, or 2 other options: now charge your mega buster or use rush coil to get edie's item, then move out. It only takes a charge shot to get rid of the next 4 enimies, so dont panic. Here, the rainbows look like your energy bar and instead of disappearing behind you, these ones disappear from in front of you! My suggustion is this: jump to the middle, walk across a little bit, then jump to the end. climb down the ladder and continue on. Jump across the next rainbow, you know what to do. And it's another bunch of rings; just run thruogh, slide under the narrow spot, and youre at ring man's door. Go on in, and if you have it, whip out your pharaoh shot; this guy is the most fast of the 8 robot masters, so you better charge it up full. ring man is prety easy, to make up for his level; He'l just run around, throwing his ring boomerangs at you. You adapt the ring boomerang after defeating him
 * 1) 1 use rain flush over and over again, or...
 * 2) 2 use bright man's weapon.**

Dust Man's Stage: Robot Scrapyard
From the start, head right, defeating the Shield Attacker. Shoot the met, and-hold on! dont jump over the pit, but get as close as you can to the edge before jumping, because an enemy is in the pit! Shoot it, jump over, shoot the next Met, destroy the next enemy, get rid of the next shield attacker, keep going right and drop down to next screen,get the energy capsule if you need it, and keep going. theres a Jumbig waiting for you, so charge your megabuster. after that, there's some things that

Wily Stage 3: Inner Walls and Teleporters/Cyberspace
For the first bit of this level, you'll be dropping down into different areas to face various smaller enemies and collecting weapon energy in preparation for your second set of fights with the robot masters. As usual, you enter different teleporters to fight each different robot. Once they are all destroyed again, a ninth teleporter appears. Time to face Dr. Wily (in a skull shaped hovership). For the first part of the fight, his machine will just hover up and down and shoot three fireballs followed by a short pause. Stand close to the machine and you will not get hit by the fireballs. Charge your Mega Buster when his fireballs are shooting. Once he pauses, jump up and shoot him with your charged shot. Repeat until his energy is drained, but it's not over yet. The skull will be destroyed and you'll be able to see Wily now. He'll also stop hovering up and down and begin moving left and right. Furthermore, he'll shoot fireballs nonstop now. His weak point is the blue jewel just below where Wily's face is. The weapon to use is Drill Bomb, but there's a certain way to do this. If the bomb hits Wily's machine, it'll just bounce off. Instead, detonate the Drill Bomb before it hits. The explosion causes incredible damage and will take Wily down without much effort. But as usual, he'll get away meaning that there's one more level to go.
