Metroid Prime 3: Corruption

Boss Guide

Guide was done by Brandon Leish also know as nazguldragon15 on gamefaqs.

Berserker Lord

    The first boss of the game is an easy one, but it gives you a taste of what the bosses to come will be like. None of them will be just a straightforward, shoot-em-till-they-die, type of boss. Each has a special method to defeating.

The boss has a couple of attacks at first. A blue "breath" attack that it'll spray out of it's mouth and an energy beam. Jump over these attacks to avoid them, locking on and strafing is a good method to help avoid. You can't deal any damage to it's health meter until you get rid of the shield protecting it's weak point. There are two noticable red orbs on it's shoulders, fire at these both until they are destroyed, then you enter the next part of the battle.

He will occasionally fire purple orbs at you, shoot the purple orbs before they hit you, and they will rebound right back at him. Once you've hit four orbs, the shield protecting him will be destroyed, exposing his weak point. Fire as many shots as you can, throwing the occasional missile or charge beam. If you don't kill it now, just repeat the process until it's dead.

Later on in the game (you will face this boss three times) the third time you fight him you can use your X-Ray Visor and Nova Beam to locate a weak point inside the Berserker Lord and you will be able to kill him in one hit. (Thank you wordlife33100 for this information).

Meta Ridley

    Your nemisis returns, and pretty early in the game. This is a pretty neat battle. Isn't it unique to be fighting a boss while falling down an extremely long shaft? I sure think it is.

The most noticable thing is the fact that you are speeding to you death down a long shaft. You don't have very much control, and there is a meter showing how many feet you have left until you crash into the bottom. However, you have plenty of time to defeat this boss before that happens. If you are running low on health, fire at the debris floating around.

If you remember back in the first Prime, during the grounded battle against Ridley, when it would open it's mouth, exposing a flaming jaw, it was about to attack you. It's the same here. Look out for when Ridley's mouth starts flaming then fire at it. Just move around to avoid his attacks, and try not to hit the wall, because it will cause some damage to you.

After a while, Ridley will fly up and grab you. Now you are falling side by side with Ridley. He will attack you with flames from his mouth, or a claw swipe. You will see when he will attack when one of these starts to glow. While they glow, it's your chance to fire charge shots and missiles into whatever body part is glowing. This prevents Ridley from attacking you.

One he lets you go, you will be falling underneath him, but the situation is still the same as it was a the beginning of the battle. He will go through these phases, just fire at him until he's toast.

Rundas

    This guy is actually pretty tough, and much longer than the previous two boss fights. My wrist was hurting at the end of the battle (but it was partially due to the uncomfortable position I was in during the fight). So prepare you wrist.

Rundas is protected by armor, and unless you can rip this away, you can't deal damage. This boss will use some physical attacks on you, so dodge those with strifing, as well as several ice attacks. If you are frozen by him, rapidly press B to break out. He will glide on an ice path in the air and land on a pillar. Shoot the ice spheres he fires at you to refill your health. While he's gliding around it's fairly difficult to hit him, so don't waste any missiles. Hit him while he's on a pillar or on the ground.

Once you've hit Rundas enough to have stunned him, he will stand still for a moment, so quickly use your grapple beam to rip off his armor. Now you need to give it your all, throwing as much damage as possible at him. This is your only chance to hurt him. Going into hypermode now is smart, just make sure you have enough health to do so. After a short time he will regenerate his armor.

Later on in the fight he will gain a couple of new attacks. He will hurl ice at you while gliding around, and he will generate a large ice pillar and swing it at you. If you see Rundas climb atop a pillar and start swinging a large block of ice, fire at his grip to make him drop it. If you don't, right as he throws it, sidestep out of the way, very quickly. This ice attack will break through the ice pillars, so don't bother hiding behind one. If you are hit by this attack you will take tremendous damage. In Veteran it'll knock off an entire energy tank. For that early in the game, that's a lot of health.

This battle can be pretty long, and difficult. If you run low on energy, stay out of Rundas' way, and just fire at the ice spheres he creats for some health and ammo. Hypermode is great, but remember that you lose an entire energy tank in the process. Use it wisely. Just repeat the process of stunning, ripping and shooting until you win.

This method was sent in by Nero Angelo to make the battle as short as between 1 to 2 minutes. It was done on Normal mode, and would take longer on Veteran or Hyper.

SUBMITTED BY NERO ANGELO
All I used was my cannon and hyper mode. While he's moving, shoot him with your cannon. When he stops, use powered up shots. Soon he jumps onto a pillar and you shoot him with 1 or 2 powered up shots before he gets stunned. Rip off his armor and go into hyper mode ASAP. Unload on him, using strafe and jump to dodge the ice. As soon as hyper mode is over, start hitting him with powered up shots again. He will get stunned again very quickly, he can be stunned on the ground it's not just pillars. Repeat hyper mode attack. He will be dead in about 2.5 hyper mode attacks, assuming all your attacks land and you don't get frozen.

This definitely takes a bit of skill on the players half. You must be accurate enough to nail Rundas enough in Hyper mode to finish the battle sooner.

Korakk

    Kind of a sudden battle. Don't forget to scan BOTH the Korakk and the Pirate Hussar on it's back. This battle won't be too difficult.

Get rid of the pirate on it's back first. The pirate will fire a red beam you can avoid by space jumping. The Korakk will attack occasionally as well. Just avoid his attacks and focus on the pirate.

Once the pirate is dead, the Korakk will get a little more agressive. Wait for it to open its mouth, and while it's glowing, fire at it. It's belly will begin to glow. Go into your morphball and let off 3 bombs under the belly of the Korakk. If you were successful, it will topple over, revealing a grapple point on the horn. Use your Grapple Lasso to pull it upright. The creature will stand on it's hind legs revealing a blue belly. Here's your chance to fire at it and deal damage. Hypermode helps a lot here too.

Repeat this process until the Korakk is a gonner. Now wasn't that easy?

Mogenar

    Here's the first of what I like to call, the core battles. Sort of like how the big bosses were the dark temples guardians in Metroid Prime 2, these are the Leviathan guardians. These generally take a bit more to beat than other bosses, but these are also usually the fun ones. They also relate somewhat to the planet you fight them on. Mogenar is a golem, and Bryyo's full of these.

Mogenar will start off by pulling red spheres from the wall and inserting them into his body. These will obviously be your targets. He has four sockets with red spheres in them. When the socket is open, focus on one and fire at it. As you fire at it, it will start glowing. You will be able to tell when it's destroyed once Mogenar recoils and the socket emitts a bright white light. Often, Mogenar will close the sockets and switch orbs around. If you've been focusing on one orb, and it is switched, it will be in a new socket, but it's the same orb. Keep track of the orb you are hitting. Ever once in a while, the boss will extend it's arms and using it's magical blue hands, it will grab two red spheres on each side of the room. DO NOT let the spheres make it to Mogenar, or all of the spheres on his body will be restored. Eliminate the two red spheres he grabs to stop this. There are three sockets on his front side, and one on the back.

After you destroy all four spheres, the second phase begins. Enter hypermode and target one of his open sockets. Once you've hit it with enough phazon, it'll explode. Mogenar will roll at you once one has been destroyed. Side step out of his way then go into morphball mode and drop three bombs at his feet to destroy those phazon crystals. Once Mogenar is upright, target another socket and obliterate it in Hypermode.

Repeat this process until Mogenar explodes, leaving you the Hyper Ball. If you are at any time running low on energy, destroying phazon crystals at his feet, or destroying red spheres will leave some spoils behind.

Steamlord

    This boss is annoying, but not too difficult. Start out by scanning the boss, the Steamlord, and the Steambots.

The Steamlord will phase in and out of existence, so don't try to attack it just yet. Every time you kill a Steambot, the Steamlord will come out to resurrect the dead Steambot. That is when you attack it. However, it'll disappear once the Steambot is alive again. Your goal is to keep killing off the steambots, so the Steamlord has more to revive. If you can effectivly kill off a few steambots before the boss appears, the boss will have to stay longer to revive more. That is when you fire all of your missiles and charge beams you can at him.

After a short time, the boss will be destroyed. It's a pretty short battle.

Defense Drone

    This boss battle isn't too hard to fight, and it's pretty simple. There are three antennas on it's head, these are your targets. While shooting these, be careful to avoid its shockwave attacks by jumping over them. Quickly finish off the three antennas or it will regenerate the last destroyed. After they are gone, the Defence Drone will be stunned. Here's your chance to rip off it's armor with your Grapple Lasso. Now it's weak point is open and ready for you to kill it. Watch out for the orbs it fires at you. Kill them quickly or they will fly around and track you until they hit you.

After it re-grows it's antennas, destroy them, and repeat the process. As the battle nears the end, the Defense Drone will get progressively faster. It will also regrow it's antennas faster, so be quick about it.

Ghor

    So now we've lost another hunter, it's so sad... but you have to admit that him beating your ship up like that must piss you off. Let's hope you are prepared. These bounty hunters are generally a bit tougher than most bosses.

He will start the battle off by creating a large shield that he'll ram you with. Do your best to avoid this attack by side stepping or morphing and rolling. Don't step into the plasma in the center of the arena, try to stay at the edges. When you dodge his ramming attacks, aim at his back and fire at an energy pack. Once it explodes, his shield will disappear and reveal a big old weak point on his head. Hit it with all you have. You can try hypermode, but be quick, because you won't have much time. After he gets up, he will fire a huge plasma beam, so jump over it.

I've recieved a great tip from Brock Mark and Aurthur Leung with stunning Ghor easier:

SUBMITTED BY BROCK MAR
During Ghor's first stage theres hot spots on the ground and if you freeze them with your ice missiles before he does is rush/charge move he will slip on them and spin out causing him to be stunned for you to shoot the thing on his back and take out his shield, I found it very helpful during veteran mode because not only did it make me more conscious of the hot spots (If you stand on them you get hurt) but I didn't have to do the jump-dash-shoot style that tires you out.

Once his health bar has drained about a quarters, he will suck of a bunch of plasma (the fuel gel in the center of the floor) and begin a new attack phase. His new weak point is an orb antenna between his legs. Ghor will fire a spinning, massive plasma beam. Jump over this and enter morphball. Roll between his legs and bomb the orb. After he's stunned by three bombs. Fire at his exposed head again, landing in some phazon attacks if you can muster.

Here is another trick from Aurther Leung:

SUBMITTED BY AURTHER LEUNG
When you get to the part where you have to hit his underside, you can use to boost ball instead to hit it. and i think one boost is enough to stun him. to make it easier, you can turn on "boost ball aiming" in the options.

If you can manage to hit it with the boost ball, then that'll quicken things up a bit.

After his health has dropped half way, he will start to spin around like a top. Jump over this to avoid it, and continue bombing between his legs during the spinning beam to stun it. Once Ghor is under 25 percent health his head is constantly exposed and he will become much faster and acurate with his ramming attacks. He will now fire a gigantic beam out of his torso, and fire several missiles. Do your best to avoid this, and quickly kill him off. Entering Hypermode and speeding up the process is a good idea. Once he's gone, rest your fingers and rejoice.

Berserker Lord II

    Remember this guy? Well he's back, and he's much easier. I was reluctant to even include him as a boss, but he does have a boss meter and everything, so I did... for fun.

Use the same technique as you did the first time. Destroy the two orbs on it's shoulders. When it fires the purple orbs at you, fire at them so they rebound against him. This time he also launches Red orbs as well as purple onces. Do not try to hit this one, because it cannot be hit back, just avoid it and aim for the purple ones. Once his weak spot is revealed, attack it with your new plasma beam. You will find that this beam deals much more damage than before. The boss will be dead in no time.

Later on in the game (you will face this boss three times) the third time you fight him you can use your X-Ray Visor and Nova Beam to locate a weak point inside the Berserker Lord and you will be able to kill him in one hit. (Thank you wordlife33100 for this information).

Helios

    Our second "core" battle is the hardest one. It takes a lot of focus. He represents the technologically advanced world of Elysia.

As you should notice, Helios is protected by this energy shield. You must find a way to destroy this so you can directly inflict damage onto our boss. He will roll around the room, and the best way to avoid this attack is to use the screw attack against the boss. If you hit the boss with the screw attack while it is rolling toward you, you won't be hurt (but neither will the boss. After a while, Helios will use his energy shield to form a spinning ring around him. He will slam it into the ground, trying to hurt you. Target the five glowing orbs in the middle with your seeker missiles, destroy them all and his energy shield will temporarily go away. Now go into hypermode and blast away his armor.

After he regenerates his energy shield, he will use an attack where pieces of his shield will begin to rapidly spin, forming a glowing core. It's target practice now, you have to destroy each of these glowing cores very quickly, before they fire the phazon beam at you. The ones glowing the lightest are more charged up, so hit those first.

Continue you strategy of removing his energy shield and attacking his armor. Helios will use his energy to create arms and legs. He will throw purple orbs at you, and stomp on the ground sending a shockwave. His weak points are the glowing spheres at his limb joints. Destroy his arms first, then his legs. If you destroy a leg first, he could regenerate it. After you've knocked all his limbs off, enter Hypermode and blast your phazon at him.

Keep repeating this process will eventually destroy Helios. If you are ever low on energy, destroying the red spheres, purple orbs, or energy charges will heal you.

Gandrayda

    This is probably my favorite boss fight in the game and it has some great music I should add. She can also be one of the hardest if you aren't prepared with enough energy tanks. She is definitely one of the hardest boss in the game to hit (and you throught Rundas was hard to hit). Gandrayda will change her forms into several bosses and enemies you have fought earlier in the game. You can scan these other forms, but only Gandrayda's scan gives you credits.

She is extremely acrobatic, and will jump around the stadium. She is extremely hard to hit, so just try to keep centered on her and fire away at her. You will probably be hit a lot during the battle because she is faster than you. She will also throw purple discs at you occasionally, and more later on in the battle.

Her first form she goes into is the Berserker Lord. You don't need to worry about destroying her shoulder spheres, just hit her attacks back at her, then fire away at her head until she transforms back into her original form. In her normal form, she gains the attack to jump on you. Shake her off by shaking your Wiimote and Nunchuck simultaneously. She transforms into the aerotrooper every once in a while, so blast that away with your missiles. She may also transform into some swarmbots. Shoot these to release health and ammo. Remember that hypermode is very helpful if you can get some hits on her.

After she's lost a quarter of her health, she will retract the roof. She will also transform into Rundas. Use the strategy you used on the original Rundas, stun her, rip off her armor, and fire away at her. Eventually she will also transform into Ghor. Wait for her to use the spinning phazon like with the real Ghor, and bomb the sphere under her legs then target the head. She will alternate between Rundas and Ghor.

Once she's lost half her health she will transform into.... you! Now you are head to head against yourself. She will go into the morphball and attempt to boost against you. Try and keep track of her movements, and jump over the boost ball. She also has the ability to fire a giant power beam attack (why don't you ever get to use this?). Jump over it, and fire at her with your plasma beam.

Once she's under twenty five percent health, she won't transform, and stay in her Gandrayda form. She's faster and more aggressive, with her projectiles and spinning acrobatics. Just hit her until she's gone. Hypermode will finish the job quickly.

Metroid Water

    This is an easy, but particularly annoying boss fight. You wil battling a few of these throughout the game.

The Metroid hatcher is hard to hit, and hard to dodge. You must hit the tips of it's tentacles until they retract. It will use a spinning attack, and fly across the room at you. This is hard to dodge, and that's partially due to she shape of the place you are fighting it in (later when you fight it again the stages are even worse). Just try to side step right before it charges at you.

After you've hit all of the tentacles, and they've retracted. It will spin to the opposite side of the room. When you see it's mouth open, and it's purple. Quickly shoot it. If you don't, it will release Metroids, and no one wants to fight Metroids. Once it is stunned, several grapple points appear underneath it. Use your lasso to rip one of it's tentacles off and it will regenerate it's other tentacles, forcing you to retract them again. If you don't manage to stun the Hatcher before it releases the Metroid, it will probably try to release another one, giving you a chance to stun it again. After a while though it will regenerate it's tentacles.

Each time you rip off a tentacle, it loses a quarter of it's health. When it regenerates the remaining tentacles after that, there will be one less tentacle to worry about. After you've ripped all of the tentacles off, the Hatcher will be dead.

Theres also a great tip I was told by Bryan Cohen and Brock Mark, concerning a "Hot Spot" on the Metroid Hatcher. When you fight this enemy later on in the game, after you get the X-Ray Visor and the Nova Beam. You can use these combined to destroy the Metroid Hatcher in one hit. This makes them much easier than the first time you fought one.

Mining Cannon

    This is one of the toughest battles in the game, especially if you do not know what you are doing. Of course, that's what you are reading this for. It's a really unique and creative battle as well. It's even pretty fun.

Your goal of this battle is to destroy that cannon in the center of the room, on the ceiling. During the battle you will encounter an infinite reinforcement of pirates (until the cannon is destroyed). Avoid the cannon. Avoid being anywhere near it! You will see why soon. Pirates will be in the room, so scan the ones you haven't yet. Kill off all of the pirates but one, (damage him enough so his armor comes off though, to make the next part easier)and then run to the wall and stay there. When the cannon's beam changes from green to purple, it will begin to suck everything in the room toward it. While hugging the wall, fire at the pirate clinging to the floor until he loses grip, and he will fly into the cannon, causing an explosion. Four orange holographic projectors will emit at the mouth of the cannon. Quickly aim up and destroy one of them. After it is destroyed, or after a short while if not, the cannon will emerge and begin firing it's green beam again.

I was told by Dasjake that you can defeat the pirates (not commandos) quickly by usin the X-Ray visor, and firing at a red-orange area on their head. There is a similar strategy for Commandos, but it involves the Nova Beam, which you do not yet have.

You can only destroy one holographic projector at a time. So repeat the process until all four are gone. Throughout the battle, different pirates will appear, and the commandos are the real threat. Going into Hypermode to blast away all but one quickly is a good idea, but remember that if a pirate throws a phazon grenade, you will overload and become corrupted. You also must keep track of several things at once in the battle, so be extremely cautious. If you are having trouble on the fight, backtrack to get some energy tanks that you missed.

* The scans in the battle include the Pirate Commandos and (the other ones I cannot remember at the moment. Email me if you have the names of the other pirates during the fight).

Pirate Commander

    This is a very annoying battle. And I do count this as a boss battle, because the Pirate Commander is a boss-like character. This boss fight may be harder to hit than Gandrayda was because of the cowardly pirates warping all over the field constantly. The field you fight them in makes it even harder. Lets hope you have plenty of energy tanks, because you could recieve a lot of damage from the Pirate Commander and four Commando Pirates he summons.

Make sure you scan the Pirate Commander now, because he's hard to scan (he's the one with red armor). The pirates will be phasing into invisibility and warping around the stadium, making them very hard to hit. They are much harder to track than the Chozo Ghosts were back in the first Metroid Prime. It is possible to use your x-ray visor for limited tracking (confirmed by Jake Knoell in an email). Check your radar for the orange dots, and enter hypermode to blast the Commandos away now. If you don't manage to hit very many in one Hypermode session, then be careful not to use it too much, becuase you need your tanks.

Try to stay in the center of the room, and right when a pirate appears, hit it and strafe around to avoid it's powerful attacks. It's hard to concentrate on all five pirates, so prepare to get hit alot.

I've also recieved email after email with tips on defeating the Commandos quickly. John M. has sent this in:

SUBMITTED BY JOHN M.
You can get 1-hit kills on Pirate Commandos. To do this you need the X-Ray visor and Nova Beam. You switch to your X-ray visor when fighting the [Pirate Commandos] and you'll notice that parts of these creatures are colored red and yellow. When you lock onto them, the visor will give you a close-up of the weak point. Just fire at the yellow weak point and voila! No more commando. Sometimes you'll miss slightly due to the zoom in function, but eventually you'll hit. In the Commander battle, it makes things easier since you can wipe out any commandos he summons very quickly, though watch out since the EMP grenades will disable your X-Ray visor temporarily and you can't see them in x-ray mode making them tough to dodge. For the pirates in the Commander battle that can't be disposed of in 1 hit, a screw attack does a good job finishing them off.

It is hard to kill the Commandos in this battle using either method because of how quickly they warp around. If you can manage to use the X-Ray/Nova Beam method, and hit them quickly enough, it really makes this battle easier. Jandro also helped confirm that this method does indeed work on the Commandos in this battle as well as all other battles with them.

After you've taken down all four Commandos, focus on the Commander. Go behind one of the side wall for cover. When the Commander is on the other side, come out and fire your Nova Beam at him. It won't cause very much damage, but it's the best way to hit him. Occasionally it will warp right next to you and hit you with a melee attack. You can tell when it will warp as it'll disappear in a white ball of light. Enter hypermode and blast it away when it appears next to you. Keep away from him at all times, and use hyper missiles when you have clear shots to blast away his armor. It won't be very long until it's dead with a few shots at it without it's armor.

Omega Ridley

    This is another of my favorite boss fights. There are lots of elements and some great music. It's also similar to when you fought Ridley back in the first Prime, but with it's own twist.

Like in the first Metroid Prime, his weak point is his heart. Unfortunately, it is protected by some armor. Fire at his mouth when he opens it to attack. It's hard to hit it though, so try and stay close enough to get some shots in, but far enough that he can't hit you. He will fire these flaming spheres at you. They home in on you, so destroy them before they hit you. These also leave behind some missiles and health. Ridley also may jump into the air and slam onto the ground, creating a huge shockwave. Jump to avoid it. He also fires a flamethrower attack that pans across your side of the room. It's very hard to avoid, or even jump over, so try to time your jump perfectly. When he is about to use the flamethrower, it's your chance to hit him in the mouth with your Nova beam. You'll be able to tell when you hit him, when he glows Yellow.

After he's been stunned, hurry over to him and rip off the armor over his torso with your lasso. He'll reveal his weak point at his chest which is only vulnerable to phazon. Enter Hypermode and blast away at his chest. After a short time he will close the armor again.

He now gains an attack where he will charge at you, very swiftly. When he opens his wings wide and it appears as if he's about to charge (it's pretty obvious), strafe out of the way very quickly. It's a very fast attack with a large attack radius, so get as far away as possible. Continue your strategy of ripping his armor off and hitting his heart. If you are confident that you can land a Hyper Missile in there, do so, but it's very hard to hit.

After you have taken off a quarter of her health, he grows a new phazon armor around his torso. You can target his heart through this by launching your x-ray visor and firing through the phazon armor with your Nova Beam. This technique doesn't do an awful lot, it isn't very effective. Ridley will use an attack where he creates two purple spheres, destroy them both and Ridley will be stunned. Pull out your x-ray visor and target these two joints on the sides of his armor. Blow them both off with your nova beam, and his armor will fall off.

Omega Ridley will use his flamethrower, but now he will spin around the room, trying to hit you with the flamethrower and tail. It's VERY hard to dodge, because you are jumping over two targets, and you must have perfect timing. If you are hit once, you will probably be trapped, and be hit by the tail and flamethrower several times more.

Once you finally get rid of the armor on his chest, Ridley will begin to fly around, in and out of the core. He will fly out of the core through the holes, so check your radar to see where he will fly back in. When he flies back in, he will start a bombing run, so jump out of the way of that. Keep avoiding the bombing runs until Ridley lands. Now his chest it totally exposed so go into hypermode and annihilate Ridley with missiles and phazon blasts until he's dead for good....or at least for this game.

Dark Samus

    Ahh, here it is, the inevitable confrontation against the arch foe, Metroid Prime, Dark Samus. Luckily, this battles a bit easier than some of your past battles. It's time to give it your all.

Dark Samus can only be hit with your phazon based attacks, and fortunately, that's all you really can do (being in constant Hypermode). Throughout the entire battle you are going to want to be firing your phazon blasts at her, as well as your hyper missiles. She is similar to Gandrayda in that she moves around a lot, and quickly. Do not get to close to her, or she generates a huge energy shield that will hurt you and reflect any projectiles you fire at her.

If she raises into the air, she will begin to absorb massive amounts of phazon, slowly restoring her health. Fire hyper missile after hyper missile to prevent he from restoring all of her health.

After recieving lots of damage, Samus will split herself apart, creating a Dark Echo. This Dark Echo is a decoy. To be able to tell the difference between the real and the echo, use your x-ray visor. The real Dark Samus will be red and orange, and the fake will be dark and black. Destroy the echo, and then return your focus onto Dark Samus. The echo will go down quickly.

Eventually she will split and form two echoes, giving you three targets to fight. Defeat these and try to avoid her charging attack. She will also raise into the air and slam into you, much like the attack she used in the first two battles against her in the second Prime. She will also fire off these white phazon missiles and they will slam into the ground causing some high damage.

After several hits, Dark Samus will finally be defeated.... or is she? Your reward to this is....

Aurora Unit 313

    Aurora Unit 313, now this was pretty expected, you must admit. This battle is going to be split into two parts, here's the first.

AURORA UNIT 313 STRATEGY

So here's the Aurora that was stolen from the Valhalla. This boss is quite tricky to even hit. It has four sockets, two on each side of it's head. When it sprouts a tentacle, fire at the end of the tentacle and it will explode leaving the socket glowing. Fire at the socket to stun the AU, and it's head will crash into the ground. Use your Grapple Lasso to rip of the armor on its head, and fire away at the exposed insides to damage it.

Aurora Unit 313 will fire a red laser and pan it across the room back and forth. Simply jump to avoid this attack.

When targeting the tentacles, a strange creature-like organ will sometimes pop out of one of the holes. It doesn't stay out very long at all, but if you manage to destroy that, the AU will be automatically stunned.

Throughout the battle, Aurora Unit 313 will summon three Dark Samus Echoes. These will be attacking you during the battle, and they will go into morphball mode and boost around the arena. Hitting it while it's in Morphball mode is pointless, so wait until it's out of that mode, then charge up your phazon beam and just let a stream of phazon out at the echo. If you don't kill it, it will eventually disappear on it's own.

After taking off half of it's health it's head will be pulled to the floor and cannons will sprout out of the ground. These fire phazon bombs that will be heading straight for you. Dodge these with space jumping. Continue your pattern of exposing the brain and hitting it unil....

AURORA UNIT - HEAD

.... it's head detaches from the spinal cord and you are against a floating head. This reminds me of Quadraxis' floating head from MP2. It is now very manuverable, but this form is still pretty easy.

It will fire a beam downward, and cause a shockwave that you jump over. It will grow a cannon out of the bottom to fire the beam, so shoot the cannon to stun AU. While stunned, strafe around it and use everything you have to hit the weak spot on the back of it's head. It will retalliate with four red laser beams. Try to stay directly under the head, firing straight up at the back of the head, this way the lasers won't hit you. It will also spin around and charge at you, much like the Metroid Hatcher. You can hit the back while it's spinning, but it won't hit so often. Quickly side step to avoid this attack.

After hitting the weak spot enough, the head will crash into the ground, leaving you the victor. CONGRATULATIONS! You've just beaten the game, now enjoy the ending cutscenes.
