Super Metroid/Wrecked Ship

Getting to the Wrecked Ship
Starting from Samus' ship in Crateria, keep heading right until you get to an orange door. Go through, and you'll see grapple points, with a Missile Tank on a pedestal underneath, with water below all that. Again, the water will slow you down so try not to fall when grappling. Drop to the Missile Tank pedestal, but make sure you notice the second part of the grapple points. The ones that appear to have cracks will crumble and reappear after some time, so grapple quickly when on them. You should have enough time to swing back-and-forth once or twice, then forward where you can jump to where you need to go before it crumbles.

Through the next door, you'll be outside again, with water nearby. Hop into the water, then head to the bottom left, below the submerged scaffold. Shoot to reveal a path, then jump and morphball to enter, and head left to get a Missile Tank. Return to the surface.

Keep heading right with the grapple points over water, but after the second there are no more points. Instead, grapple onto the Gripper flying to-and-fro. It'll remain in place upon the beam hitting it, where you can continue right to a green door, which signals the entrance to the Wrecked Ship.

Starting the Wrecked Ship: No Power
The Wrecked Ship is currently lacking power, and you must find a way to restore it to explore the whole thing. Go right past the entrance room to reach the main shaft. Across from here is a Save Station, but it is currently inoperable. As you are exploring the powerless ship, you may come across ghostlike Coven enemies which come into existence near you. As they're appearing, they won't damage you, so don't worry about going too fast and hitting them. Once they appear, you can ignore them if they're not in right front of you, or shoot them. To continue, head down, ignoring the first locked door. On the left platform, bomb the wall to get to a passage where you can find a Missile Tank through the path. There are spikes in this passage, but because of the lack of power they won't hurt you, even if you touch them. Now head to the bottom of the main shaft. If you aim down, you can shoot away some of the pipes, allowing you to reach a green door in ball form. Enemies called Atomics are encased in glass domes. Ignore or kill them, but take the door on the floor.

In this room, head right, bombing the obstruction in the tunnel. Another Gadora eye door blocks the boss room to Phantoon. A single Super Missile will get rid of it quickly.

Fight with Phantoon
When you enter, you will see a circle of blue flames, which cause damage should you touch them. After a while, the flames will merge and the boss Phantoon will appear. He will start out in a transparent state, flying around left and right and dropping blue flame “tears” from his closed eye. Be ready to dodge the tears, as they bounce on the ground, but can also be shot, possibly awarding pickups. The tears can only be shot after their first bounce, though. Eventually, Phantoon will disappear, then reappear in solid form with its eye open and throw flames in a circular pattern from the eye around the room. The first time its eye opens, it may disappear again quickly, with flames dropping in random spots afterwards. After that, it'll drop eight flames from the ceiling upon appearing again, which will not bouce. Some will drop on one side, then after the rest will drop from the other, so watch out for which side they fall on first, though it is also possible the entire line will fall in sequence. At this point, Phantoon's eye will remain open for some time, so try to get a hit in now. To do damage, shoot the eye with a Missile, Super Missile, or charged shot. Super Missiles will cause Phantoon to retaliate, however, by shooting multiple circles of flames around the room about eight times, which is hard to avoid. To not take damage from this, just make sure to charge the normal beam immediately after hitting with a Super Missile, then flip jump to activate the psuedo-Screw Attack, allowing you to not be damaged by the flames. The flames won't even break your jump, so you can just keep the charge going.

This pattern repeats, so remember to be on the lookout for moments when the boss' eye is open. Upon Phantoon's defeat, power is restored to the ship. So, head back left.

Wrecked Ship After Phantoon
You may see loose wiring with green sparks, so be sure not to touch it. Anyways, keep going left, and the cylindrical Work Robots are now awake. They do no damage if touched, but shoot a slow ring of energy. They cannot be destroyed, but can be pushed back with normal hits. Also, the previously trapped Atomics are now free and floating around, and can be taken out with normal shots or Missiles. Return up to the main shaft.

The first door on the left is unlocked, so go inside for a Super Missile Tank.

In the main shaft again, bomb across this door for a secret area. In here flying enemies called Bulls are found. They'll try to fly into you, so use Missiles or charged hits to take it out fast. Dash on the conveyor belt, and jump on the platform with the robot, making sure to time it so you don't get hit by the spikes on either side. Repeat this for the next platform, then bomb jump and leave a bomb next to the wall to reveal an area which you can get to by bomb jumping again. Inside is a Super Missile Tank. Head to the main shaft again.

Keep going up, past the next door, and you can save across from the entrance. Go to the top, where there are more pipes on the ceiling which can be shot away. From here, keep going up, through the door in the ceiling. Here, the doors are locked until the Atomics and Kihunters are destroyed. The Kihunters in this room are slightly more powerful than they were before. If there are green sparks above, it is possible for smaller sparks to fall from the ceiling, so be careful of that. Once the enemies are all gone, take the flashing right door.

The conveyor belts move quickly in this room, so dash on them and jump over the spike pit. Keep shooting the robots while moving right until they fall into the spike pits, so you can make a safe passage to a Missile Tank. Again head to the left room, killing the enemies. This time, take the left flashing door.

Back Outside
You're outdoors again, in an upper part of Crateria. A Tripper can be found left of the grassy floating platforms. Jump atop it, waiting until another one comes into view above it. A third is above this one, and you can shoot the wall left of its path to reveal a Missile Tank, which you can get to with a flip jump.

Now go bottom left, where the X-Ray Scope reveals a spot that can be Super Missiled to enter the tunnel system. As soon as you land here, bomb the left side to get to a Missile Tank. You'll need to destroy the bombed segment and jump then morphball to escape, otherwise if you fall you'll have to enter the Wrecked Ship again. Super Missile the top again and get out.

Now head a bit right, and the X-Ray Scope will reveal another segment into the tunnels that can be shot. Take the right tunnel path through the door. Wavers are here, as well as a new enemy: Chutes. These enemies will hop straight up, then slowly descend while moving left and right back to their starting point. The Grappling Beam is a quick and cost-effective way of getting rid of both enemy types. Take the next two doors right to get back inside.

To the Gravity Suit
Grapple points must be utilized above to head right, over the spikes. The points become more difficult as they lessen in number, and the last set will crumble. At the end is a standing Chozo Statue with no items. Turn into a ball on its hand, and it'll awaken. Then, it'll walk harmlessly into the spikes, and drop you in a hidden area.

Once the Statue lets go of you, bomb the floor and take the right tunnel. The pipes in the way up and right can be shot, where you'll find more robots which must be shot into the spike pits. Continue right to get a Missile Tank. Use a Power Bomb here to get rid of the statue and wall behind it. Ahead is a conveyor belt, and you must run across it to Speed Boost, where you can Shinespark up the right small path in the ceiling. You may want to start your run to the left of the trapped robots. At the top, the X-Ray Scope will show that the first flashing green bar is actually a pit. So, jump over it to get to a Reserve Tank. Now fall down the pit, and continue left through the door.

Shoot the ball in the middle and collect its contents to get the next suit upgrade: the Gravity Suit. Aside from the purple color change, this suit allows for freedom of movement underwater, allowing new areas to be reached. Also, you will take 75% less damage from enemies.
