Mega Man 3/Walkthrough

	Mega Man 3 is divided in three parts. First, as in every Mega Man game for the NES, there is a selection screen with eight Robot Masters to defeat. Whenever Mega Man defeats a Robot Master, he gains a special weapon, that is very effective against another specific Robot Master.
	After the eight Robot Master have been defeated, the mysterious Doc Men appear. Mega Man 3 is the first game in the series where there are some stages between the initial Robot Masters and the Skull Fortress. In later NES titles, there will be another fortress before the Skull Fortess.
	This third "selection" screen prompts to the final stages, but before Mega Man reaches the Skull Fortress there is one short stage against the mysterious Break Man.
	The Skull Fortress is made of six stages, as it was in Mega Man 2. These are the longest Skull Fortresses in the series: later games feature four stages only (even less in the Game Boy titles). Actually, Mega Man 3 is the longest game in the classic Mega Man series.

Suggested order

Unlike most Mega Man video games, in Mega Man 3 there are two separate chains of weaknesses:

1. Chain A:
   1. Top Man is weak against Hard Man's weapon;
   2. Shadow Man is weak against Top Man's weapon;
   3. Spark Man is weak against Shadow Man's weapon;
   4. Magnet Man is weak against Spark Man's weapon;
   5. Hard Man is weak against Magnet Man's weapon;
2. Chain B:
   1. Snake Man is weak against Needle Man's weapon;
   2. Gemini Man is weak against Snake Man's weapon;
   3. Needle Man is weak against Gemini Man's weapon.

Also consider this:

• Top Man and Magnet Man suffer 2 HP Damage from Mega Man's arm cannon, while doing 1 HP Damage to the others. These are often chosen for starting points, though Top Man is easier platform-wise.
• Beating Shadow Man gives you Rush Marine, which is useful for Gemini Man's underwater areas.
• Beating Needle Man awards Rush Jet, which is very useful for areas that have pits like Spark Man and Magnet Man.

Therefore, a possible suggested order is as follows:

Robot Master	Boss fight & weapon	Items & stage
Top Man	Mega Buster for 2 HP Damage. Obtain Top Spin
Shadow Man	Top Spin for 7 HP Damage Obtain Shadow Blade	Obtain Rush Marine
Needle Man	Shadow Blade for 2 HP Damage Obtain Needle Cannon	Obtain Rush Jet
Snake Man	Needle Cannon for 4 HP Damage Obtain Search Snake	-
Gemini Man	Search Snake for 5 HP Damage Obtain Gemini Laser	Use Rush Marine
Spark Man	Shadow Blade for 4 HP Damage Obtain Spark Shock	-
Magnet Man	Spark Shock or Shadow Blade for 7 HP Damage Obtain Magnet Missile	-
Hard Man	Magnet Missile for 4 HP Damage Obtain Hard Knuckle	-

The Doc Robots can be done in any order as there are no significant changes upon level completion other than an E-Tank in Needle Man's Stage.
