Mega Man 3 Walkthrough

Level Strategies
Although it is possible to complete the eight main levels and four Doc Man stages in any order, this walkthrough provides a recommended order that will make defeating bosses and some enemies easier. However, there is no need to follow the order given, and each level strategy can be read alone.

Needle Man
The first thing you will have to pass are a few large hedgehogs. They shoot their needles at you and then roll towards you. Jump over them when they roll if you can't kill them in time, make your way past them and climb down. You'll see two paths; the lower one is a dead end but has a large weapon capsule guarded by a Met. Taking the top path to continue, shoot the turrets when they open to pass. Next will be a series of Mets and dragonflies, (and are those giant Mets buried in the ground?) pass them and go down. Large spikes periodically shoot from the celeing to the floor in this room. Slide through the passageway when the first spike is retracted, then go down and repeat the process. Run under the next sets of spikes quickly or slide under. Jump onto the platform here, time your next jump to avoid yet another spike, jump to the ladder and climb. There will be another hedgehog here, this one is harder to avoid because of the uneven ground. Jump over him and, if you want to, use Rush Coil to reach the energy tank. Climb up and defeat the Joes here. You can only shoot this enemy when its eye is open, and you can slide under or jump over his mace. Climb again and slide under the jumping enemy when it jumps. You cannot kill this enemy, and it will cause significant damage to you, so be careful. Needle Man has two attacks. One is to jump high into the air and shoot four needles at you, the other is to bend forward and extend the spikes on top of his head. Jump carefully inbetween the thrown needles, but be more cautious of the head spikes as they do a high amount of damage. Slide under him when he jumps to avoid this attack. You can shoot him at any time, his weakness is Gemini Laser, and if you use that, you can fire it anywhere and it will probably hit him because of his erratic jumping. You get the Needle Cannon and Rush Jet for defeating him.
