(Dont do it wile his back is turned or its shell will block your attack. So just keep doing that until he dies and turns into a Core-X (a ball with a lot of little spikes all over it). Once that happens you should hit it with a missile and it will start flashing, dont waste your missiles then they wont do anything, but if you do use up all your missiles just shoot it with a regular shot and some green, and yellow blobs or the X- parricides will come out, collect these. The green ones will increase your missiles, and the yellow ones will increase your life. After you do jump over it (wile its flashing) and shoot it with more missiles. Then just repeat until its dead and it will turn into a floating blob, jump and absorb it. It will give you the Morph Ball ability! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The Core-X Now this ones one of the easiest bosses to beat as long as you know what to do with those spike balls shown after every boss you defeat in their normal form. The only other two things you need to know is one how to get it to battle with you, and two to shoot in the rite spot. O.K. now for the first one all you need to do is find the statue and shoot the little ball in its hands. The ball will float up and turn into another Core-X, with one catch; it has an eye that you have to shoot so instead of just shooting it only shoot it when its eye is open. Then as soon as you shoot it jump away, because it will shoot back. After you defeat this boss you will get the Charge Beam which is about twice as strong as the normal shot, but takes some time to charge up all the way. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Cyclops Leech This one can be a little tricky the first time you battle it but so is every other boss out there. But all you really have to do here is shoot up its mouth after it jumps up but make sure you get out of the way before he comes down on you. If that does happen your only defense from it sucking out all of your health is by planting as many bombs as you can and it should drop you. It will take about 5 times before it turns into another Core-X. When you do beat it you will get the High Jump, and the Ball Jump. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Serris O.K. when you first go into the room were the map says Serris is you would walk into the water with nothing there. Go out the other side of the room and you should see were you should have gotten an energy tank jump up to the living door, beat it and walk in. Serris wont come out until you step on the middle of the big platform above the water and everything will shake. Now Serris will come raging out flashing, just get out of the way until that stops then find a position of the room you like the most (it doesnt matter were you are) and shoot him in the head, he will start to jump around flash, like before just get out of the way. Until he stops get back in your position and keep doing it and after the 5th shot or so its body will fall of and the head will spin around until it turns into its Core-X form and just do everything like all the other bosses and this one has an eye too. One thing about battling the Core-X you should know is to NEVER GO UNDER WATER! It will slow everything do down but doesnt do anything to the Core-X it will kill you faster than you can get out of the water. Once you beat him get the blob that comes up over the middle. It will give you the Speed Booster that you need to lower the water level and get out of that place. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Security Robot The malfunctioning security robot can be really hard or really easy, when you first go into the room with the little ladder thing all you will hear is a bunch of crashing noises but walk over to the right side of the room and he will jump out at you. After that quickly jump onto the ladder on the ceiling, then go directly over aim down and pumble it with the new super missiles you just got. Then when he raises his canon thing run away until the fire bomb hits the ground the stay there until the fire starts going up and down towards you, once it goes down climb over top of his like before and do the same thing. The other security robot that you will face is a lot harder but has the same concept so remember how to beat this one. Once you beat this one unfortunately it wont give you any new ability, probably because you just got the super missiles. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The Big Core-X This one is easy all you have to is charge up your beam and hit him with that instead of missiles about 10 times. Then a regular old Core-X will appear. This one prize is about 20x greater then how hard this guy is. Anyway just dont fall in the water (like Serris) and you will get the Varia Suit. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reactor core Spider Most people think this boss is too hard to beat but its not as long as you know were to hide. When you drop into the room on the ground there are three lines on there go over to the last one on and stay there. Then once the spider thing comes down he will spray fire just stay were you are and you wont get hit. Then when the fire goes away roll over all the way to the wall. Now that you cant be hit by the spider you have to know when to attack. You should still be in a ball but if it starts to move around again stand up and try to follow were it goes unless it is to low to the ground but if that happens just go back into a ball and roll back over to that left corner. If it doesnt then he would climb up and open his mouth to through fire at you go directly under it and keep hitting it with missiles. If you keep repeating that its body will fall of and its head will jump around shooting things but gust get under it and shoot missiles they will block the things it shoots and damage it. After you beat it you will get the Space Jump ability, which lets you jump as high as you want at a steady pace. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Giant plant thing This thing is easy once you drop in the room jump up to the high platform and just keep giving out energy bombs it kills the little pollen being shot at you and it hurts the big thing sticking on the wall. By the time you run out of energy bombs the thing should have already been ticked and will start shooting plasmas at you but its not that deadly because you can see them coming and just shoot missiles at it. If its shooting low jump up and shoot at it. If it is high duck and shoot at it simple. Then it will flake of that wall and turn into a core-x. after beating it you should have guests that it will give you the Plasma Beam. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Nightmare Night mare can be extremely difficult. Once you drop into the room, stand in the middle and wait for the boss. Once Nightmare shows up, there are two choices of weapons. Ones a charged up beam shot the other is missiles. Go with missiles theyre much quicker. Shoot at the canon until the gravity is too overwhelming. Then switch to beam until the canon is gone. Then climb up on the ladder and missile it in the face. Youll earn the Gravity Suit as a reward. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Bot Part 2 Same thing as the other but a lot harder to beat. Walk into the room plant a power bomb and go on the ladder. The only difference is the projectiles have changed. Shoot them down. This time you will get the powerful Wave Beam. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Ridley You may have heard that this boss is hard but hes not at all. All you gotta do is shotem up the but no missiles needed. But he does have thing where he freaks out and shoots fire or somm at you. After you beat him you will get the O mighty wave beam that can shoot through stuff. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ SA-X Ahh now this one is kinda hard but not really. Charge up your beam and perform a screw attack over it, the SA-X should copy you, thats when you fire the beam repeat till defeat and same thing with the monster. The only reward you get this time is relief . O ya and at the end he like morphs to this thing and tries to jump on you a lot. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Omega Metroid Alight now you tring to leave but this thing stops you and its really hard and blah blah blah. Once you go back to the ship after engaging the crash sequence, you will meet up with an Omega Metroid. Let it swipe you and no matter how much energy you have, you will be downsized to one point and no tanks. Do not worry the SA-X will come and take a few shots at it and the Metroid will kill it with one swipe. Collect the X and perform the same thing dodging the claw attacks. Also you gotta try to shoot it in the mouth. Thats it you win! ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Ok I really hate to bore you and everything but dont try to copy this ITS HARDER THAN IT LOOKS. k whatever bye This Has Been an Lpninjaz Production The End
