Defeating the Alpha Blogg:  To defeat the Alpha Blogg, you must first scan him if you want a good ending. However, this is optional. Once you are fighting him, make sure you always have him locked on. Sometimes he will shoot air bubbles at you, then charge at you. When he is charging, charge the Power Beam. Just before he hits you, fire the Super Missile. Do not do this too soon or late or you will hit his side. You will still get hit, but it will not do much damage if you have the energy tanks. Keep doing this until he is defeated.

The Alpha Blogg can be eliminated the same way you would take care of the normal Bloggs. The only differences are that you can move freely with the Gravity Boost and that the Alpha Blogg shoots sonic waves which will stun you and your gun for a few seconds. To kill it, charge your Power Beam and wait until it rams you. When it gets close to you, it will open its mouth. At that point, shoot like mad. The Super Missile will damage it the most. After you shoot, strafe and dash using Left or Right and B. Repeat this about four to five times to win.

After obtaining the Gravity Booster, you will have to face Alpha Blogg. While fighting this giant Boss, keep an extremely far distance from it. When attacking, Alpha Blogg can do one of two things. It can shoot blobs of goo which causes you to lose sight and lower your gun, or it can charge at you like regular Bloggs. If it starts shooting you, side-dash to dodge it. It will most likely charge at you afterwards. While charging, it will open its mouth just before it hits you. You can shoot a charged Power Beam shot or a Super Missile into its mouth. After shooting it, immediately side dash to dodge it because it does not stop charging after it gets hit. This Boss is not difficult if you keep a safe distance away from it.

Defeating Amorbis:  There are two stages where you will encounter Amorbis. In one stage, Amorbis will leap into the air and back into the ground, where its impact will damage you if you are close to it. Use your radar more often to see where Amorbis is located. Stay inside the Light Crystals to avoid being damaged by the atmosphere. As it leaps up into the air, shoot it with the Power Beam, Light Beam, or missiles. After several hits, it will be time for stage two. On stage two, it will stay at the center of the arena and will use its physical attacks. Be careful, as Amorbis will also disable the Light Crystals. Move on to the next one if that happens. It will also shoot multiple blue energy beams on the ground. The best way to dodge these is to morph into a ball inside the Light Crystals and hover around the energy beams. Blast Amorbis down with the Power Beam, Light Beam, or missiles. Its head will explode and it will try to suck you in. Quickly form into a ball and let it suck you in, then drop some bombs inside it. The battle repeats both stages again, but with two, then three worms and it gets tougher. Once Amorbis is defeated, the Dark Suit is yours.

Defeating the Bomb Guardian:  The fight will begin with you fighting an Alpha Sanddigger for a brief moment. First, when the Alpha Sanddigger is not infected by the Dark energy, shoot it in the face with a few Power Beam shots (like a regular Sanddigger). In a few seconds, the Alpha Sanddigger will get infected by Dark energy, transforming it into the Bomb Guardian. The Bomb Guardian is fast -- never stand in one place. It also has a variety of attacks. As you might expect, the Bomb Guardian uses your morph ball bombs against you. It will throw bombs at you, leave some behind as it slithers across the arena, and hurl some out of its mouth. The easiest way to evade the bombs it throws is to keep your reticule locked on to it and strafe. Its other attacks include charging at you, and biting you if you get too close. You should also lock on and strafe to avoid these attacks Note: When you avoid the Bomb Guardian's charge attack, it will get behind you, making you lose your lock-on. When this happens, quickly turn around and lock back on to it. During the battle, you will notice a purple glowing thing on its tail. Lock on to it and shoot it when you get the chance while avoiding its attacks, until it is red and not glowing. Two Charge Beam shots should be sufficient. When you shoot it, the Bomb Guardian will prepare its attack. While it is doing this, shoot it in the head to whittle down its health. Be careful, as it will soon hurl some morph ball bombs from its mouth. It is practically possible to avoid this attack -- do not get hit more than one time. Repeat this process until it is dead. When you kill it, you will obtain your morph ball bombs again. Note: When the Bomb Guardian throws bombs at you or charges at you, its weak spot on its tail will stop glowing. Ignore this, as you still cannot damage it until you make it stop glowing.

Defeating the Boost Guardian:  In this battle, your energy will slowly decrease because of the Dark atmosphere. There are no Light Crystals to help you. There are four pillars in the room, and each contains the Ultra Energy Unit when broken down. They are essential to your survival. The Boss will take two forms, normal and liquid. When in its normal form, blast it down with a Super Missile, as it will damage him the most. The Boss will then form into a morph ball and start spiking through the room randomly. Jump over it, or form into a ball to get out of its way. Also watch out for its minions. After three to four spikes, it will follow you on the ground in maroon liquid form. Quickly form into a ball, roll around, and drop bombs behind you. It will repeat spiking and forming into liquid again. Repeat this and it will finally revert back to normal form. Blast it with the Super Missile and repeat the entire process until it is dead. Once it is defeated, the Boost Ball upgrade is yours.

Before you enter the hole to the Boss' chamber, switch to the Light Beam. By doing this, you will start with it when you are out of morph ball mode. When the battle begins, you will automatically change out of morph ball mode. Either scan him or begin charging your Light Beam (which will be your default) and try to get two or three shots on him before he starts glowing. When he glows red, he is temporarily invincible. When he is in ball form, switch to morph ball mode. This will make avoiding his minion Ing easier. If you can, drop a morph ball bomb in front of him before he charges off -- look for the line down the middle of his ball form. He will charge in one of those two directions. If the blast hits him while he is in ball form, he will instantly turn into his liquid form, in which case he will follow you around. Drop M.B.B.s to damage him. If he starts boosting around before you hit him, roll around, dropping morph ball bombs and try to avoid him. If he hits the bomb blasts while he is moving, he will stop and turn into his liquid form. After about three bombs in his liquid form, he will change back to his solid form. Change back to your gun mode and repeat those steps. He should die after about three repetitions.

Defeating Chykka Larvae:  This first part is actually very simple. Basically, just stay in the center and fire. The larvae just swims around in a circle, then dives down. Get ready, because it will jump out of the water, allowing you to cause some damage to it. However, when it crashes into the water, make sure you jump over the shockwave or it will knock you into the poisonous water. Occasionally, it will send some Dark Shredders against you. Just shoot them with charged shots or missiles. They are mainly there for refills. Eventually, the larvae will emerge from the water, exposing its front. Use Light Beam charged shots as many times as possible. You should leave this battle with almost all of your health intact. You will also be constantly healing due to the Light Crystal field. Eventually, it will "die".

Defeating Chykka Adult:  The field is divided into three platforms, each separated by nothing but a grappling point and poisonous water. The Chykka Adult has a projectile attack that easily blasts you off the platform and into the deadly water. The Chykka Adult must first be stunned by shooting it up front. Then, you must grapple onto a platform behind the Chykka Adult and shoot its wings (preferably with Super Missiles to just hit each point one by one). This can prove to be very difficult if you have not mastered the Grappling Beam. The Chykka Adult will not stay stunned for long -- be quick about it. After destroying all four weak points on the back of its wings, the creature will fall into the water and mutate into the Dark Chykka Adult. The only thing you can do to this creature is shoot its pouch. Take out the Light Beam and blast away. Charged Light Beam shots work the best. It may sometimes launch a group of small creatures at you (mainly to kill and get some refills). After defeating the Dark Chykka Adult, it will revert back to the normal Chykka Adult again. You must repeat the same process again; stun the creature, grapple behind it, and blast the back of its wings with missiles. It may sometimes try to run into you, but usually fails. Then when it turns into the Dark Chykka Adult, use the same strategy and hit its pouch with charged Light Beam shots. This battle could take a while, so be prepared. For all your efforts, you are awarded the Dark Visor.

Defeating Ing:  After getting the Annihilator Beam, any Ing you encounter will be easy to defeat. Shoot an inactive Luminoth Light Crystal with the Annihilator Beam. This will cause any Ing to seek the light given off. The Ing will walk into the light and die. This is an easy way to conserve ammunition and energy.

Beam Effects on Luminoth Light Beacons:  Different beams have different effects when shot at a Luminoth Light Beacon.

Power Beam: Charges beacon and offers protection from Dark Aether Atmosphere for a short amount of time.

Light Beam: Charges beacon for an extended amount of time.

Dark Beam: Temporarily extinguishes beacon. Note: Only the Light Beam can change it back, or you can wait for it to change back by itself.

Annihilator Beam: Supercharges beacon for an extended amount of time and causes any surrounding Ing to walk into the light causing it to die. This is very helpful if you are low on energy or ammunition.

Light Suit:  After restoring all the power to the Agon Wastes, Torvus Bog, and Sanctuary Fortress Temples, talk to U-Mos and he will give you the Light Suit. The Light Suit enables you to teleport from temple to temple. The Light Suit also takes away the damage taken from walking in the Dark Aether atmosphere.

See Samus' face:  Walk to a wall and face it. Charge up your beam and shoot it to reveal Samus' face reflecting off her helmet.
