With Zero and X united again, they continue to fight Mavericks and restore peace to the world. A misterious doctor appears claiming that he can "cure" Reploids that have been change into Mavericks. This doctor, Doctor Doppler, keeps his "patients" in a valley where they have everything they need. Like it's own civilization. Everything thing was looking up for the Hunters when they recieved notice of strange activity coming from the valley. X and Zero rushed to the scene to find Mavericks everywhere that had not been cured. Something was up and X and Zero had an idea that the good doctor was behind it.
Ray Splasher - Fires a rapid-fire stream of blasts across the screen. When charged it creates a small gun turret in the air the shoots in all directions.
Gravity Well - Fires a little gravity altering device the causes nearby enemies to explode. When charged the gravity is reversed and the enemies float away.
Parasitic Bomb - Fires a mechanical projectile (pretty boring not charged). While charged four targetors are around Mega Man and they lock on to enemies and automatically fire at them (Very useful!).
Frost Shield - Creates a spike of ice that flies across the screen. Underwater the spike gets larger and more powerful. When charged it creates a shield that sticks out of Mega Man's blaster and can be used as a melee weapon.
Acid Burst - Shoots little balls of acid... Charged, Big balls of acid that bounce around a little before they splash.
Tornado Fang - (Most useful weapon in the game) Fires small flying drills. When charged a drill sticks out of Mega Man's blaster and can be used to hang on walls.
Triad Thunder - Three little electrodes cause an electric field around Mega Man. Rapidly press the Y button to make the field last longer. When charged Mega Man pounds the ground with great fury!!!
Spinning Blade - Shoots 2 little flying blades. When charged it shoots a giant blade out like a Yo-yo and if you press up it will rotate around Mega Man.
As you may have noticed from the opening stage, you can play a little of the game as Zero. Zero isn't really a crucial part of the game. He's harder to control, he's bigger (making him an easy target), and he's slow. The only thing nice about him is his kick-ass beam sabre. To switch to Zero, hit L in the subscreen menu and hit start to summon him.
Zero cannot fight any bosses, so whenever you come to a boss door, X will automatically jump back into the action. You also have to be very careful when playing as Zero because he only has ONE life! If that life goes, then that's it!! You don't get him anymore for the rest of the game. Zero is such a hassle to use, you'll probably start playing as X and forget about Zero when the novelty of him wears off.
The link below shows all of the locations of every Armor Part. In this game you have the traditional 4 armor parts, but in addition to that, there are 4 pink capsules that give you chip upgrades. The catch is that you can only have one of the 4 chips for the rest of the game. I have supplied pictures to help.
Bit's pattern is really easy to see. He keeps jumping up in the air then he dashes at you when he's at your level. So get off of the floor! The only thing you have to watch out for is the little hoops that hold you in place and the chasing fireballs. Both are easy to dodge though. If you use the Frost Sheild on him he'll be finished. You can still beat him without the frost shield, but then you'll have to fight him again in the Doppler stages. Best to eighty-six his sorry ass now.
Byte will do nothing short than TICK YOU OFF!!! He shoots a stupid little object that pushes you away from the oposite wall of the room, preventing you from climbing. Then he rushes you and does this little painful 3 hit combo that leaves you in shambles. About three of these combos and you're done. The only way to beat him is to stay at the top of the wall before he launches the object. Then just hold against the wall until you almost touch the object, from there jump hard to the oposite side of the room and Air-Dash with the Boot enhancement. You will safely fly over Byte's head and to the other side. Quickly turn around and unload a shot of the Ray Splasher on him, then climb the wall to the top and repeat the process. The Ray Splasher will get him where is hurts and he'll say goodbye in a firey serious of explosions. If you didn't use the Ray Splasher he'll see you again in the Doppler stages.
Vile is pretty easy the first time you fight him, if you can find him. He waits for you in an old shutdown power plant. The only way to get to the power plant is through teleporting capsules that are placed in certain levels. The easiest capsule to find is right at the beginning of the Volt Catfish stage. You ride the first elevator you see down to the room below and there it is. Below is a list of levels that the teleport capsule is in and where it is. Vile's pattern is easy, he rushes you and tries to hit you with his Attack Carrier. He can't get off of the ground so that's where you don't want to be. The carrier can be easily destoyed with the X-Buster. Then you'll fight Vile on foot. Use the Ray Splasher on him to finish him off for good (Unless you wanna play with a stronger and more exhausting Vile in the Doppler stages).
- After you go through the battle room that you would fight Bit or Byte in there's a point where you will see a Energy capsule below. That capsule is a lure to the invisible opening in the floor that takes you too Vile's Teleporting Capsule.
- Go through the level until you reach a ladder with a pit below it. Slide down the left hand wall to the capsule.
- Get on the First elevator platform in the level and ride it down to the capsule.
**NOTE: These capsules will only appear if you haven't beaten Vile yet. If you beat him in Volt Catfish's stage then you won't see the capsule in either Blizzard Buffalo's or Crush Crawfish's stage.
All E-tanks, parts, and Hearts. No gold or sabre.
Golden Mega Man X:
There is a way to get ALL of the extra armor chips in Mega Man X3. In the first Doppler stage play until you reach the area with the rolling spiked balls. Slide down the left hand wall of the first pit in that room. You will fall into a hole in the wall and there will be a pink capsule. This will give you every Chip enhancement AND turn Mega Man Gold.
**NOTE: This will not work without full life and you cannot pick up any of the Chip enhancements in the levels earlier.
Zero's Beam Sabre
In the second Sigma level there is a miniboss bug bot that is right after the water-filled area. Switch to Zero right before you go through the door. Then use Zero to fight this boss (This is the only boss Zero can fight). When you when in the fight, Zero will be wounded and he will give X his Beam Sabre to use for the rest of the game. You will not be able to use Zero anymore, but you will have the strongest shot in the game. Charge Mega Man's X-Buster up until you turn green. Then when you fire the 3rd shot, it will be the Beam Sabre.
**NOTE: You can only fight the miniboss in this stage if you defeated Vile earlier!!
Sigma Stage Bosses
If you destroyed Bit and Byte earlier in the game (see above how to destroy them), you'll have to fight the Elephant boss. Use the Ray Spasher on the face until the nose is destroyed. When this happens, green liquid fills the bottom of the room and you're forced to hang out on the wall. To top things off, a giant hand keeps trying to grab you and deal tons of damage. Keep jumping and sliding to avoid the hand and shoot the face as best as you can. You may have to resort to a Sub Tank in this battle.
Bit and Byte-
If you left either 1 or both Bit and Byte alive, you'll have to fight their combined form (which is much easier than the Elephant Boss in my opinion!). The easiest way to beat this guy is to charge up the Parasitic Bomb and use it's automatic homing feature. This way, the weapon does all the attacking for you, and all you have to do is dodge the attacks. Pretty easy fight with that weapon involved.
If you destroyed Vile earlier in the game (see above), you'll have to fight the Octopus Boss. This boss is the better of the 2 deals. Get up in his face and bombard him with the Triad Thunder weapon. He shouldn't last very long.
If you didn't kill Vile earlier, you'll have to fight him in his huge Goliath carrier! Use the Parasitic Bomb weapon or the X-Buster to destroy the carrier. The walls will be your main tool for dodging him when he rushes you. After the carrier, he'll then be on foot. Use the Ray Splasher weapon on him. Watch out for his fire and ice moves because they deal lots of damage. You might need a Sub Tank to get through Vile.
Dr. Doppler isn't very hard if you're careful. When he uses his green force field, he can absorb your shots and convert them to his own life. So don't shoot him when he's got the shield up. Use the Acid Burst weapon on him. The best time to shoot him is after he dashes through the air and is falling back to the ground. He won't be able to use his force field until he gets to the ground. If you manage to nail him with a Charged shot of the Acid Burst, it does a lot of damage.
Sigma is a pain because all of his moves do pretty heavy damage, and they're hard to avoid. He shoots fire from his arm, and throws that shield of his around like a boomerang. He also uses the shield to block your attacks. Use the Spinning Blade weapon because you can fire it over his head, and it will double back and hit him from behind. If you have time to charge it, it will deal more damage to him.
The hardest thing about Kaiser Sigma is hitting his weak point, his head. Always keep your X-Buster charged and use the combined double shots on him. You want to aim for just above the little blue cannon that shoots the multicolored beam. Since he's so big, there's not a lot of places he can move to. When he flies in the air, it's to move across the screen. All you'll need to do is slide under him. Use the X-Buster to fight off the homing missles and cling to the wall to avoid his multicolored beam. He's not that hard as long as you can shoot him.
