RockMan X2

Instead of using the X-buster, the quickest way is to use Flame Stag's weapon.

To defeat Serges in the X-Hunter levels, use the G. Crush to destroy the four cannons, then use the Sonic Slicer to damage Serges.

When Sigma's wire-frame head turns red he will disappear and reappear around you unless you move quickly. Let him surround you and quickly select your Strike Chain. Keep shooting the Chain at him. This weapon should be as powerful as a charged blast.

Use the Sonic Slicer when fighting Sigma (with the claws).

Use Magnet Mines to destroy the four guns on the Big Machine.

After defeating Sigma's first form, you have to fight him in virus form. He has no energy bar, so you will just have to hit him with all you have got. To hurt him, you must hit him in the eyes with the Third or Final Charged Shot. Anything lower will not work. The Dragon Punch will work, but it is difficult to stay at 100% health in this fight. Sigma will change colors when he gets weaker. He will drop minor enemies onto the floor. Destroy them to get energy capsules. When Sigma turns orange, he will start teleporting around - do not be where he forms or he will trap you. Just keep dashing away from him. Keep shooting and victory will be yours.

Use the Bubble Beam.

In case you have to fight Zero, use the following tricks. There are only four weapons that will harm Zero: the Third Charged Shot, the Final Charged Shot (Enhanced Cannon required), the Speed Burner, and the Dragon Punch. Zero will block any other weapon. Note: The Dragon Punch will strip half of his health away. When Zero dashes at you, climb up the closest wall you are near -- after he stops dashing, he will pound the ground, causing four rocks to shoot up. You can jump over them. Zero has two projectiles. One is a small green shot which he will fire if you are shooting at him. The second is his trademark Z-slash combo, where he will fire two Third Charge Shots and end with a Beam Saber Slash. The shots will not hurt much, but his Beam Saber will cause drastic damage. Be careful and you will defeat Zero with ease.

Look in the ceiling or cave tops to find hidden items and other objects. Note: This is mainly on stages where you cannot see the ceiling, such as Flame Stag or Bubble Crab.

To Enter Metamorph Moth's level after defeating Wheel Alligator, then use the Helmet Search. Where its signal falls, shoot with the Spinning Wheel. You will find the Armor Capsule.

If you do not get all of Zero's parts you have to fight him until he breaks through Sigma's powers. Here are a few items that could help.

Zero does not stall at all before he shoots his triple shot, so make sure you find the capsule where you get the "ultra charge". Climb a wall as soon as he starts shooting and charge your blaster. Zero should dash over to you and smash the ground, which will cause rocks to appear and hit you. Avoid this by quickly jumping off the wall and on to the floor. By now your weapon should be fully charged. Shoot one mega-blast to block Zero's first blast, then wait until the second blast is about to hit you. Then, shoot the second blast to block the one that is about to hit you. Some of the blasts surrounding the second blast should block Zero's cape swing. Finally, the rest of the blasts surrounding the second one should hit Zero. This will take one line of energy away from Zero.

Another way to damage him is to use the Speed Burner. Note: This will not block shots, so wait until he is not on the offense nor defense. The Speed Burner will not damage him if he is blocking.

To block shots easily and quickly, use the Spin Wheel. Note: This will not harm Zero -- it will only block shots.
