Mega Man 3/Weapons and Bosses

• Arm Cannon - Your regular weapon, simply press B to fire. You can have three shots on the screen at a time.
• Magnet Missile - Magnet-shaped projectiles that fly quickly and curve to hit a target. Very useful against hard-to-hit enemies that may try to attack you from above.
• Hard Knuckle - Slow-moving fist-shaped projectile. Difficult to use due to its initial slow speed and rate of acceleration, but very powerful. Its vertical position can be adjusted slightly by pressing and holding either or after firing. Can destroy walls that the arm cannon can't.
• Top Spin - Mega Man spins like a wild man, damaging whatever he touches, and sometimes himself. Due to its unpredictability and general uselessness, I don't recommend using this weapon except for in certain circumstances.
• Shadow Blade - A short-ranged throwing star that can be somewhat aimed. The aiming makes it useful, but it lacks range. Still, it's useful in many situations.
• Spark Shock - A fast-moving spark is fired forward. Pretty powerful, too. There are a number of situations where this will be useful.
• Search Snake - Snakes will crawl along the floor, damaging the first target they hit. Very useful for those hard-to-hit ground-based foes who may lurk below the range of your Arm Cannon.
• Gemini Laser - A blue laser will be fired, which will bounce off walls until it hits a targer, or until it eventually fades away. This is a powerful weapon, but only one can be on the screen at a time. For best results, use at close range, and don't miss the first shot.
• Needle Cannon - Mega Man can rapid fire needle-shaped projectiles. If there's an enemy weak against rapid-firing, this will be your weapon of choice!
