Your first few minutes

Begin: Press Start at the title screen and choose a Robot Master stage. Regional title screens and difficulty choices can differ.
Try first: Use the Mega Buster to practise one screen of movement and shooting. Open and close the weapon menu before attempting a difficult jump.

Default keyboard: Arrow keys move · Z = controller A · X = controller B · Enter starts · V selects. Controller labels in the guide refer to the emulated pad; check input settings after remapping.

Stuck or stopping for now?

If you get stuck: Special weapons have separate energy. Check the selected weapon and energy gauge before treating a failed shot as a control problem.

Keep your progress: The game password and an emulator snapshot preserve different things. Read the password limits in the guide and download a snapshot backup for the exact running position. Open Save / resume below the player. Test a small save and restore before a longer session.

On a phone: Turn to landscape and check the touch controls after launch. Physical Android and iPhone compatibility has not been verified.

About Mega Man 2

Mega Man 2 — Famicom edition — Mega Man 2 · Famicom · 1988

Mega Man 2 lets you choose eight Robot Master stages and reuse defeated bosses’ weapons in later encounters.

The stage order is part of the puzzle

Stage selection is part of the puzzle. Each Robot Master gives Mega Man a weapon that can help against another boss or a stage obstacle. Weapon energy is limited, while movement-support items create additional ways through difficult sections.

Revisit your route after a victory

A defeated Robot Master gives you a weapon another boss may be weak against. Reconsider the stage-select screen after each victory. The support items also create platforms, so a new item can change how you approach an awkward ladder or gap.

Console sequel, not arcade boss rush

This is the Famicom console sequel, not Mega Man 2: The Power Fighters, which is a separate arcade game.

Background and mechanics: Wikipedia game reference.

Mega Man 2: weapon energy, E-Tanks and password limits

For the NES/Famicom game. The English instruction guide supports the mechanics below; no complete boss-weakness route or regional ROM identification is claimed.

Learn Mega Man 2 weapon selection, energy pickups, E-Tanks and Wily-stage password limits with Nintendo manual references and practical route advice.

Input	Action
A	Jump.
B	Fire the selected weapon.
Start	Open the weapon menu.

Begin a stage attempt with a clear purpose. For movement practice, use the Mega Buster and learn where you can stop safely. For a weapon experiment, choose one obstacle and compare the result there rather than changing weapons at every screen.

Keep a short record of the stage, weapon and result. “Useful on the upper enemy, poor from below” is more actionable than a list of weapons you happened to fire. This guide does not give an unverified universal boss order.

Equip the weapon that needs the pickup

The Mega Buster has unlimited shots. Special weapons use separate energy; an energy pickup refills the weapon currently equipped. The eight main stages restore weapon energy at their start.

Pause before collecting a refill if several weapons are low. Look at the next section and choose which tool you want available there. Collecting it while the wrong weapon is selected can leave the one you need without help.

When a special weapon solves a movement or enemy problem, mark that location in your notes. On a later attempt, use it at the known obstacle and practise the remaining section with the Buster. That makes resource use deliberate.

Decide when an E-Tank should rescue an attempt

An E-Tank restores health, and you can carry up to four. It does not refill every special weapon.

Choose a point at which you will consider using one, such as reaching a fight you want more practice with. Check the health meter before the next risky exchange, while you still have time to make the choice.

After spending a tank, record what the extra attempt taught you. If the same attack catches you again, work on the position or timing next time; repeating the same sequence with another tank gives you less useful practice.

A password is not an exact fortress checkpoint

Passwords appear after a Robot Master clear or a game over. In the password grid, A places a marker and B removes one. A password for the Wily portion restarts at the beginning of the fortress.

Keep a screenshot of the grid with a note about what you had completed. If you want to return to a particular running scene, use the emulator’s separate state options and keep the older backup until you have checked the replacement. A grid screenshot and a state file serve different purposes.

Common questions

Why did the pickup refill the wrong weapon?

Weapon-energy pickups refill the weapon equipped when you collect them. Select the one you need first.

Does an E-Tank refill special weapons?

No. An E-Tank restores health; special-weapon energy has its own pickups.

Why did my password restart the Wily fortress?

The password system resumes the Wily portion from its beginning, rather than a later fortress stage.
