Mega Man X:
Mega Man X returns to action, this time he volunteers to enter the Maverick Hunter HQ's Mother Computer to remove the virus that is causing the computer to act strangely. This time though, X must relieve his past as he battles against the first Mavericks he fought and defeated long ago. With help from Zero and Middy, X is determined to reach the core and defeat the source of the virus - most likely Sigma. As always, X's strong sense of justice and unending dedication to maintaining peace will see him through this mission.

Zero:
Zero also returns, this time assisting X but not taking much part in the action. Zero stays at HQ, leaving X to enter the computer and defeat the virus alone. Meanwhile, Zero clears away the Mavericks who have emerged during the confusion caused by the virus, and he helps Middy maintain X's status and position in the computer. The reality of Zero's past and creation take a break during this game.

Dr. Light:
Dr. Light plays his usual role, waiting in the hidden capsules for X to find. He'll give X new upgrades to help him survive in the heat of battle. The usual four upgrades will be available - as well as a hidden capsule containing two special moves.

Dr. Cain:
Dr. Cain makes a few appearances during the game. Usually with Middy, Dr. Cain follows X's status in the computer and assist X by providing him with information and hints to further X's progress.

Middy:
Middy is a new Reploid designed to work with computers, and after some time, he became a well-known genius at his work. Allowing X to enter the Mother Computer, Middy maintains X's status and helps him make his way through the heavy data files. Always willing to help the Hunters, Middy has proved to be a reliable and trustworthy ally, although he does have secrets of his own...

Techno:
Techno is working with the Mavericks Zain and Geemel to hack into the Mother Computer to cause chaos. He was originally Middy's twin brother, but he was infected with the Maverick Virus and began working for evil. He is under Zain and Geemel's command, and will unquestioningly destroy Middy if he has to. Hidden well within the Maverick's hideout, Techno is well protected, but as all Mavericks, he underestimates X's true power.

Geemel:
Geemel, along with Zain, has managed to hack into the Maverick Hunter's Mother Computer, infecting it with a virus which causes complete chaos and confusion. Using this to their advantage, the two Mavericks have built up a small force of Mavericks and are beginning to attack the world. Too overconfident for their own good, Zain and Geemel are about to find out why Vile, Agile, Serges, Violen, Bit, Byte and several forms of Sigma have all lost against one reploid - Mega Man X.

Zain:
Zain is a powerful Maverick working along with Geemel to attempt to succeed where Sigma and many Mavericks before him have failed. A strong and skilled fighter, Zain is eager to battle X and is confident that he can match X's power and crush him, but he underestimates X's power, the usual flaw of the Maverick virus. Zain will battle X more than once before X can reach the core of the Mother Computer.

Sigma:
Sigma returns in his first original form, re-constructed from the past data from the Mother Computer. As the core of the virus causing riot in the computer, Sigma has almost complete control over the system, managing to access Maverick data and effectively revive his long-dead Maverick soldiers. Not the core leader of the operation, Sigma can only remain inside the computer and wait for X to confront him, where he hopes to crush X once and for all. Sigma's only disadvantage is that he has no new bodies or moves, he'll re-use the same tactics that he used during their first battle in the original Mega Man X.

Normal Mode Bosses:

Storm Eagle:
Guide: You will find Storm Eagle waiting for you on the Maverick's ship. He will often use wind attacks against you, including his storm tornado gun which can be avoided by jumping over or dashing through. He will also often flap his wings which will cause X to move back. Make sure you don't fall off the ship by dashing toward the Eagle and firing at him all the time. He will occasionally fly up into the air and spit out an egg in which four bird-like creatures will hatch from and fly towards X. If he flies right up out of the screen, dash in one direction as he will swoop down out of the sky and try to hit X. You'll need to use the X-Buster to defeat Storm Eagle, try to use charged shots often.

He will also often shoot out two blue or red fireballs. When he charges at you and jumps up the walls, try to dodge him by jumping away from the direction he is going to evade him. To defeat him, use the Storm Tornado. Each time you hit him he will either fire two fireballs or jump at you, so dodge the fireballs by jumping up the wall and then over them and fire again or dashing under him as he jumps over. Shoot him when he lands and jump over him as he jumps on the wall.
Weakness: Storm Tornado.
Weapon Received: Speed Burner.

Chill Penguin:
Guide: Chill Penguin will begin by firing out four mini ice blocks one at a time. He will also sometimes use a dash and slide attack, where he will slide across the floor attempting to slam into X.

Chill will then jump up to the ceiling and pull on a lever which will cause a huge blizzard and will blow X against the wall, causing damage. To defeat Chill Penguin, use the Speed Burner. Try to hit him before he fires any ice blocks, and if he jumps up to the top of the screen, shoot him down. Continue this and he won't survive much longer.

Spark Mandrill:
Guide: When you face Spark Mandrill, he will probably charge and try to punch you. He will use this attack often, so be careful.

If he jumps to the top of the screen, he'll climb across the roof and drop down when you're under him, so be ready to dodge him as he falls. Use the Shotgun Ice to beat him. When he charges at you, fire once and he will freeze for a few seconds. Wait for him to break out of the ice and when he stops flashing, fire again. Keep doing this until he runs out energy.
Weakness: Shotgun Ice.
Weapon Received: Electric Spark.

He'll jump at X often, bringing his sword down to try and crush X with. After a few jumps, he'll land and spin around, slashing his sword around himself. To defeat him, use the Shotgun Ice. When he jumps, dash under him and fire at the wall. The ice block will rebound off the wall and hit Zain in the back. If you have time, you can also hit him directly in the back. You can't shoot him from the front, he'll just block your shot. Stay away from him when he spins around. Keep hitting him from behind and he won't last long.
Weakness: Shotgun Ice.

Zain (Second Time):
Guide: Zain will use moves similar to those during his first battle with X, but he'll be stronger and will move around faster. After jumping three times, as he lands after his fourth jump, he'll use his spin attack but will move around the screen at the same time. Jump up the walls to dodge it. Use the Shotgun Ice to defeat him. Fire at him from behind each time he jumps for the first two jumps, when he lands, go near him, as he'll jump low on his third jump. Go up the walls after his fourth jump as he'll use his spin attack. Repeat this through each of his attack cycles to eventually finish him off.
Weakness: Shotgun Ice.

The Spider:
Guide: After battling Zain, the next boss will be a large mechanical spider. It will remain at the top of the screen most of the time, and you will notice before it attacks, several horizontal lines will slide across in the background and join together the parallel vertical poles. These poles indicate a path the spider can take to try to climb down and slam into X. It will also often spit out an egg in which four small spiders hatch and crawl across the screen. When the spider reaches the bottom, a large red eye will open on its back. Make sure you constantly charge up your X-Buster to full power, so that when the red eye appears, shoot it with the fully powered blast to damage the creature. This is the only way you can damage it, but repeat the sequence and it should be defeated fairly quickly.
Weakness: X-Buster.

Serges:
Guide: Serges returns! He will battle you in the large vehicle above a large bed of spikes. There will be three moving platforms for you to stand on. Serges will enter in a large vehicle which has four gun turrets on the front. Each turret will fire out a different energy weapon when Serges moves up and down and fires one. To defeat him, shoot each gun turret with the X-Buster until they explode. When you destroy one, the vehicle will move forward and destroy one of the moving platforms. When you destroy all of them, The front part of the vehicle will explode and Serges will be exposed. Stay on the moving platforms and shoot at Serges with the Speed Burner as he rises up the vehicle to finish him off. Try to dodge the small energy balls he fires and keep away from the spikes.
Weakness: Speed Burner.

Sigma:
Guide: Sigma, as usual, is difficult to beat, as he can cause massive damage to X. He will fight you with his old light saber-type sword. When he attacks, he will charge at you swinging his sword. If he hits you about a third of your health will disappear, so you must make sure that you have full sub tanks before fighting him. He will often jump across the room off the walls and charge into you. To defeat him, use the Electric Spark. You will find that if you shoot at him when he's standing still, he'll block your shots. Jump up the wall and charge your weapon to full power. When he jumps up the walls and is opposite you, release the Electric Spark and you'll shoot out two spark walls which will fly through him and cause a lot of damage. Drop to the ground before he hits you and continue the process until you destroy him. If you are low on health do not hesitate to use a sub tank.
Weakness: Electric Spark.

Sigma's Final Form:
Guide: When you face Sigma the second time, his head will appear at the bottom of the screen and rise up into the head of a huge machine which is set into the wall. The final form of Sigma will be difficult to destroy. First, its attacks include the head of the machine firing a huge Fire Wave across the screen which causes huge damage if it hits you. Avoid it by staying against the left or right walls. The head will also fire out Electric balls which also cause huge damage. Dodge them by dashing through the gaps between each ball. The two floating claws next to the machine will often shoot energy beams above and below themselves. To defeat the boss, wait for a claw to open and shoot energy beams. If it opens again straight after closing from an attack, it will fly down to X and try to hit him. The fully charged X-Buster will inflict the only damage you can to Sigma. Jump on top of the claw and make sure you have charged your X-Buster to full power. As it rises back to its original position, jump off it and fire your weapon onto Sigma's head. You will have to do this several times. Try to stay up in the top right or left corner, From there you can easily fire off shots at Sigma while not having to worry about his Fire Wave and Electric Spark attacks. Remember to use sub tanks if your energy is low. Eventually you will destroy Sigma, finish the normal mode game and gain access to the hard mode!
Weakness: X-Buster.

Armored Armadillo:
Guide: Armored Armadillo's main attack is a rolling attack in which he will fly across the room and bounce off the walls in an attempt to crush X. He will also often fire energy beams out of his forehead. You will find that if you shoot him with the X-Buster, he will block most of your shots with his shield. You can still defeat him this way, but if you use the Electric Spark, he will be electrocuted and his shield will fall off, leaving him open for attack. Continue shooting him with the Electric Spark while dodging his energy beams and you will eventually defeat him.
Weakness: Electric Spark.

Morph Moth:
Guide: Morph Moth will begin the battle as a small object hanging from the ceiling. It will swing around the room and release pieces of junk which will damage X if they hit you.

 CONGRATULATIONS!!!
You finished Mega Man Xtreme.

X-Buster:
You'll begin the game with the X-Buster. As the standard weapon, most enemies can be defeated from sustained fire or a few charged shots. You'll need to X-Buster to proceed through the stages, but you'll need special weapons gained from defeated bosses to inflict heavier damage on certain bosses - the X-Buster will only slightly damage the bosses.
 

Normal Mode Weapons:
 

Storm Tornado:
The Storm Tornado weapon is gained once you defeat Storm Eagle. This weapon's primary fire will shoot out a long gust of wind which can strike through targets and cause more damage than a regular shot. The blast will either completely destroy the target or damage it and blow it further away from X. The charge-up fire will create a huge swirling vortex of wind around X and will destroy any targets above or below him.

Speed Burner:
The Speed Burner is gained when you defeat Flame Stag. This weapon will fire out a large flame-ball which will scorch any targets it strikes. The charged-up state is useful, as it will cause X to fly straight ahead a small distance while flaming red, so that any enemies he strikes will be destroyed. This can also be used to reach items normally out of reach or in a dangerous area.
 

Shotgun Ice:
The Shotgun Ice weapon is gained after you defeat Chill Penguin. This weapon's primary fire is an ice block which can either damage targets or sometimes freeze enemies. If the block hits an obstacle such as a wall, the block will break and smaller projectiles will reflect back off the wall. The charged state of the weapon creates a platform which X can ride. Once the platform is created it will slide forward for a limited time.

Electric Spark:
The Electric Spark weapon is gained once you defeat Spark Mandrill. The weapon's primary fire will shoot out an electric spark-ball which can damage or electrocute targets. The charged state of this weapon will fire out two giant walls of electricity either side of X and can destroy any targets they strike through.

Hard Mode Weapons:

Rolling Shield:
The Rolling Shield is gained after you defeat Armored Armadillo. The primary fire of this weapon shoots out a large blue ball that bounces across the screen until it hits a target. If it hits a wall, it will reflect off it and continue on in the opposite direction. The charged-up state will create a defensive shield around X. This will protect him against any enemies who try to strike X. Energy projectiles will be deflected, but if a strong solid object strikes the shield it will turn off.

Silk Shot:
The Silk Shot is gained once Morph Moth is defeated. This weapon will fire a small ball-shaped projectile which will land on the ground in front of X and shoot out four smaller projectiles in diagonal directions. This can hit any enemy normally out of reach. The charged-up state will attract a large amount of junk towards X, which will fly out and spread projectiles across the screen once fire is released.

Magnet Mine:
The Magnet Mine is gained once you defeat Magna Centipede. This weapon will fire a small mine-projectile which will continue flying straight forward until it hits something. When it attaches itself so an object, it will detonate after a few seconds. The charged-up fire will shoot out a small energy ball which will continue to fly through targets once it hits them and cause more damage than a normal shot.

Spin Wheel:
The Spin Wheel is gained once Wheel Gator is defeated. This weapon will fire out a small metal wheel which will slowly launch away from X and roll through any enemies and cause damage, as well as being able to destroy certain walls. The charged-up shot will fire out eight energy beams that will fire away from X in a circular fashion.

The Shotokan/Haduken Capsule:
The Shotokan Capsule will give you both the Haduken move from Mega Man X and the Shuryuken move from Mega Man X2. To get it, go to the second Shadow Hunter stage. At one point there will be two ladders. One will lead downward into the rest of the stage. The other will lead upward. Take the upward ladder by maneuvering the floating platform toward it. Once up there, use the Dash-Jumps and wall clings until you come to a complicated set of spikes. Charge your Speed Burner weapon and Dash Jump toward the spikes, then turn around quickly and let loose the charged Speed Burner. You should be safe now, so cling to the wall and let it lead down to the capsule. Remember that the capsule will only appear if you've gotten all the items and upgrades available to you, whether it be Normal, Hard, or Extreme mode.
