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 double damage from Mega Man's arm cannon;
• You want to obtain the Rush Marine (from Shadow Man) before the stage with underwater areas (Gemini Man's);
• Snake Man's weapon is extremely useful in Top Man's and Shadow Man's stages.
• Beating Needle Man awards Rush Jet, which is very useful in Spark Man's and Magnet Man's stages. On the other hand, it makes the game less challenging.

Therefore, a possible suggested order is as follows:

Chain	Robot Master	Boss fight & weapon	Items & stage
B1	Snake Man	Fight with Mega Buster (N. Cannon) Obtain Search Snake	-
A1	Top Man	Fight with Mega Buster (H. Knuckle) Obtain Top Spin	Use Search Snake
A2	Shadow Man	Fight with Top Spin Obtain Shadow Blade	Obtain Rush Marine
A3	Spark Man	Fight with Shadow Blade Obtain Spark Shock	-
A4	Magnet Man	Fight with Spark Shock Obtain Magnet Missile	-
A5	Hard Man	Fight with Magnet Missile Obtain Hard Knuckle	-
B2	Gemini Man	Fight with Search Snake Obtain Gemini Laser	Use Rush Marine
B3	Needle Man	Fight with Gemini Laser Obtain Needle Cannon	Obtain Rush Jet
