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
