Metroid: Other M/Sector 1

Entering Sector 1
You have to go to the main elevator. Use the elevator that goes to sector 1. Go to the navagation booth.

Pink Lizards
As you adventure through Sector 1, and encounter these 2 pink lizards. You blast them with a missile to make them visible. Then start blasting them with missiles and charge beams, until they die.

Breeding Room
You go through a spiral ramp. Go across the first bridge, into the navagation room. Save your game, and go on to the next 2 rooms. You will have to fight 3 shelled things. The best way to beat them are lethal strikes. Go through the only avaiable door. Take a morph ball passage, to obtain a missile tank, and to go to another portion of Sector 1. Go down the stairs, into a hallway. Go to the end of that hallway. Go through the door at the end. You will be in the breeding room. Go into the next room, and Samus will fell the presence of a dark intelegence. Go back into the breeding room.

No Access
Go back to the room with stairs. Go into the other room that you can access, and have not been in yet. Go into search view mode, and blast at the zoomer with a missile. Take the morph ball passage, and back into the room with the morph ball passage. Go back to the room where you fought the shelled things. Locate a mouse thing in the room. Adam will unlock the door that you were not able to open before. You will go on to another navagation booth. After saving, the door to continue will be locked. You will have to use a bomb on the left wall to move on. Continue on until you reach 2 more pink lizards.

More Pink Lizards
You defeat them the same way you defeated the other 2 pink lizards.

Floating Robots
2 robots will come out. You have to wait for them to charge up their lasers. Shoot their cannons with charge beams. When you kill 1, another will pop up. You have to kill all 3 of them. After you defeat the last one, you will get the diffusion beam.

Fly Nests
You will go into a room with 2 fly nests. First you have to all the flies. Then, you just have to blast each of the nests with 3 missiles. So you will use 6 missiles total.

Boss Battle: Fune and Nomie
First you have to wait for one of them to stick their face out of the wall or ceiling. Blast one of them in the face with a missile. When it pops out, blast his orange spots with charge beams, until it is downed. Hit the downed worm with a lethal strike. Do it all again on the other worm. Now you can use the terminal to unlock the door in the navagation booth.

Biological Test Floor
First, you have to get back to that navagation booth, and go through the door that you couldn't go through before. Go across this room. Find a morph ball passage, and go through it to deactavate the first force field. Find the second force field. Use the same morph ball passage to reach the terminal to deactavate the second force field. Find a hidden passage on a rock. Go through it (reactavate the 2nd force field if you have to.) Now you are in the biological test floor. Go up the spiral ramp, into another room. Blast through all of the obsticals. The last one will have another shelled thing. Kill it. Go through the purple tunnel.

Boss Battle: King Kihunter
This is a pretty tough boss fight. It will begin when you spot some small brown creatures. First, kill all of his little Kihunter minions. Then 5 flowers will open up. You have to blast all 5 of them with a missile. The purple nest will fall after that, and you have to kill more Kihunter minions. Now for the final stage. Blast King Kihunter with 5 missiles. After that, he will turn to stone, it will show a cutscene.

Are we close or not?
Adam gives you a mission to go to the Biosphere Test Area. As you go on, there will be a water room. You have to hit a lot of charge beam switches to get through it. After that, you continue exploring until you get to a room with a lot of trees.

Boss Battle: Groganshious
This boss can shift forms of a giraffe and a spider. He is simple to beat, though the takes several hits. You beat this boss by constantly shooting his orange ball. While you are shooting him, you have to dodge his purple balls that will damage you. In some time (my wild guess is 4 to 5 minutes,) he will be defeated.

Coming Closer
Just run along to the Biosphere Test Area. I think there is only one way to go anyway.
