After completing the game in normal mode, both hard and easy modes will be unlocked.
In easy mode, you do not need to bother updating your digging license; your first license will allow you to go into all ruins. Additionally, the lady at the Digger's Guild will not let you take the test. Also, Zenny found when destroying Reaverbots
are worth more, while shop prices are less and Bosses are easier.
Getting concealed Zenny:
Zenny may get stuck in the wall or on a mountain from time to time. To get the Zenny (Refractor Crystals) off the wall or side surface, simply stand next to it and jump. The Zenny will fall off the wall and you will land on top of it.
Invincible to electricity:
If you wear the Hover Shoes, you will be invulnerable to electricity.
For any Boss, a good strategy is to equip a special weapon that you can run with while shooting, such as the Machine Buster. If possible, take a Hyper Cartridge. Run around them using the sideways run, turning to adjust your path every once in a while. Along with jumping, you should be able to avoid most of the attacks. Shoot the special weapon to wear them down, and use your Buster to finish them off. Note: If you have the Laser, it is much more useful than any other weapon. Note: If you are fighting Sera, wait until it is in the second form to use the special weapon.
In the ruin in which you acquire the second key, take Drill Arm with you.
If you are having trouble with the Jellyfish, get close to them. A full
Drill Attack should kill one. Do this on all three of them. If done correctly without any setbacks, you should defeat them. You can also use the Drill Arm on.
You should be able to defeat him easily if you use the Drill Arm correctly.
Successfully complete the game under the very hard difficulty setting.
Start a new game and look at your Buster parts. You now will have the
Accessory Pack Omega, which maxes out all of your abilities.
If you shoot a Shielder with any high impact weapon, its shield will be
blown away allowing it to be hit more easily.
Find a pig near the home of Shu and her brothers on Carbania Island.
Keep on kicking the pig and Megaman will get darker, then the pig with a couple of kicks/throws later. Note: If you do this you will not be able to take the Mayor's Quiz on Manda Island.
