Mega Man 3/Walkthrough

Suggested order
Unlike most Mega Man video games, in Mega Man 3 there are two separate chains of weaknesses:
 * 1) Chain A:
 * 2) Top Man is weak against Hard Man's weapon;
 * 3) Shadow Man is weak against Top Man's weapon;
 * 4) Spark Man is weak against Shadow Man's weapon;
 * 5) Magnet Man is weak against Spark Man's weapon;
 * 6) Hard Man is weak against Magnet Man's weapon;
 * 7) Chain B:
 * 8) Snake Man is weak against Needle Man's weapon;
 * 9) Gemini Man is weak against Snake Man's weapon;
 * 10) 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 Shadown 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:

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.
