AM2R/The Tower

Reaching the tower
Outside of the entrance to the Research Site, the lava that once rested at the surface of the pit has receded. You can now head down and explore the tunnel. From room A, begin dropping down to the bottom to reach room B below. As you get close to the bottom, you may encounter a new species of creature that pops out from the wall sporting what looks like two spinning circular saws. After a time, it will retreat back into the wall. You will see these from time to time as you make your way to the next section.

Continue to follow the tunnel down as you maneuver through room B. You will notice a Missile Tank in an isolated chamber on you way. See Missile Tank A below to learn how to obtain it. When you reach the bottom, continue to the left to room C. Many creatures will confront you as you drop to the bottom. It's best to ignore them as much as possible to reach the bottom quickly. There, you will have the choice to go left or right. To the left is a save station. Save your game, and then take the right exit to room D.

More of the circular saw creatures will dog you as you make your way to the bottom of room D, which levels off and heads to the right. This leads to room E, which is a simple straight fall down to the bottom. The only exit heads to the left to room F.

Room F contains a number of insects, and the floor is lined with a pool of lava. Make your way down and to the left to reach room G. Room G is a long corridor, also filled with lava. It has two different creatures; a bird-like creature that rises continuously out of the lava, and another creature with very shielded wings that deflect your current beam. They normally hang in place until you get close enough for them to track you. Continue to the left to reach the entrance to the tower.

Item Gathering

 * Missile Tank A (room B): Along the very bottom of the room, there is enough space to run from the right side to the left, and build up enough speed for a Shinespark. Squat down to the store the Shinespark, and return to the spot on the ground beneath the highest point in the ceiling.  Jump straight up to crash through that high point in the ceiling, revealing a tunnel up to the missile tank waiting in the small chamber.


 * Missile Tank B (room F): The missile tank in this room is hidden in the lower right corner of the room, behind a wall that can only be broken with the Speed Boost. There are two ways of getting to this tank.  The intended way takes a bit longer, and requires that you travel to the opposite side of room G and build up enough speed to Shinespark all the way across room G to the right, and into room F where you crash through the wall to collect the tank.  However, you can also build up enough speed by running to the left from room E and stopping just before the ground drops to the lava below.  The only trick is that you have to store the Shinespark, and then jump diagonally through the air so that you dodge the two closest insects and land on the platform below.  From there, you can hop over to the lower platform on the right.  Then press jump, and hold right so that you crash through the wall and collect the tank.

Goals
You begin in room A. Two boulders seem to block your progress to the left, but they are easily removed with a single bomb. Head to the left to room B. Like many other sections you've visited, there is an outside exterior to the tower. Unlike other sections, this exterior is broken up into four sections; one to the left, one on the top, and two to the right. Room B is the lower of the two sections to the right of the tower. You have a lot of freedom as to how you tackle this tower. In fact, you can go around and defeat all six Metroids without exploring the Tower much at all, but you'll be leaving a lot behind. For now, simply hop left over the surface of the lava to the entrance of the tower. Go through the door to room C.
 * Getting your bearings

Inside the Tower, you'll notice that it's incredibly dark, as the power source has been turned off. Space Jump your way up to the door at the top, and step inside. Even the save station room is dark, but at least the station is functional. Save your game, and continue left to room D. Drop to the bottom of this empty room and head left through the door. You're now in room E, the section that contains the exterior to the left of the tower. Room E contain two exits to the left, both of which lead to Metroids. If you start Space Jumping up along the wall of the tower, you'll spot one entrance which is colored yellow. Yellow doors can only be opened with Power Bombs, an item you don't yet have. As you keep going up, you'll notice a hole in the wall. At this time, you can choose to enter through the hole in the wall, although you may wish to visit room F above to try an collect a few items, including an Energy Tank before you continue.

Use the hole in the wall alongside room E to access the upper portion of the tower. You will literally arrive directly below a Chozo statue holding an item orb in room I. However, from this portion of the room, you are helpless to collect it. If you explore the narrow passage in the lower right side of the room, you can use it to access room J. After bombing your way out of the passage, you can explore the entire room, but the power to both doors is disabled, so you can't use them. Your only alternative is to roll along the narrow passage on the bottom of the room to the right, and drop down to room K below.
 * Powering up the tower

Room K indicates that there's an item hidden somewhere, but if you bomb the brick below the bottom of the passage, the tile will indicate that you need Power Bombs. Bomb the block to the left to access the rest of the room. Once again, the disabled power prevents you from opening the door. If you bomb around the lower left corner of the room, you'll find yet another passage that drops you down to room L below.

Follow the passage as it bends to the right. Then bomb your way to the narrow chamber below. Your goal is to reach the bottom, and to do so, you'll need to bomb a block on the floor of each chamber. Even when you reach the bottom, all you'll find is a deactivated door. Bombing the lower right corner, however, will provide you access to another hidden passage. This one will lead you down to room M below.

Room M is pretty dark and has deactivated doors on either side as well. What it also has is a contraption in the middle of the room, with a slot just big enough for a Morph Ball to fit in. Shrink down and fit inside the slot. If you do this, you will act as a switch, activating the electricity in the tower, and powering up all of its systems. The left door will remain closed, but the right door is now accessible.

With the Tower powered up, you can now attempt a return trip to room I where you saw the Chozo statue. Unfortunately, it won't be that easy. From room M, take the right door to room N. Two different types of robots will be moving about, but only one is a threat. A flying laser sentry will fly down to attack you. Destroy it before you move on. The other type of robot is a repair drone that is only interested in attending to the tower and ignores you. Jump up to the top of the room and head left back into room L.
 * Obtaining the Plasma Beam

When you enter room L, you'll be in a small chamber. Ignore the armored robot floating along the ceiling. You need to access the passage below the chamber. Bomb the lower left corner of the chamber to open a path to the passage. From here, you will be repeating the process of bombing your way through the chambers to get to the bottom. The only difference is now the Tower is activated, and the devices attached to the walls of each chamber fire electric beams across the chamber. This makes it difficult to bomb your way down without taking quite a bit of damage. Try to time your drops down into each chamber so as to avoid the electric beams as much as possible. Definitely don't hang around by the bombs and allow yourself to be thrown up into the beams. Once you reach the bottom, open the door on the left and enter room O.

As soon as you enter the room, the camera will shift to alert you to the presence of a giant flying machine known as the Tester. The Tester's purpose is to assess the effectiveness of a large number of weaponry. And true to its purpose, it is about to test a variety of weapon systems on you. Be prepared for a long fight.

The Tester has several components. It has four armored segments that surround it. It can rotate these segments around itself to any desired configurations. However, once these segments are sufficiently damaged, they are permanently destroyed. These armored segments are immune to beam weapons and can only be destroyed by concussive explosions. The Tester also has four cannons. These cannons can fire a wide range of weapons, including giant laser beams, heat seeking missiles, reflective beams, and pulse orbs. The cannons can be shot and destroyed, but once the Tester retracts them, it can restore them for use with the next weapon it chooses to fire. The inner core is what makes the Tester function. Unlike the armored segments, it is immune to concussive blasts, but it is vulnerable to beam weapons.

Your goal is to strategically remove the armor to expose the core, and then pelt the core with your main weapon until it is destroyed. To destroy the armor, use up your Super Missiles (you won't risk missing such a big target and you'll get more throughout the fight) and then continue chipping away at the armor with Missiles until all four segments have been removed. Then focus on attacking the core with your normal weapon. Whenever you destroy a segment of armor, you get a cache of missiles. You get a variety of items for every cannon you destroy, along with items for each destroyed heat seeking missile.

Surviving the fight requires you to adopt a different strategy based on what weapon is being fired. The reflective beams are slow, but they scatter around the room whenever they hit a wall. The pulse orbs primarily fire up and down, so you're safe on the sides of the room. The heat seeking missiles can be fired out of the air with relative ease. The weapon which requires you to move the most are the giant laser beams. The Tester fires them in four directions and rotates around in a counter-clockwise direction. You'll need to stay in a safe zone if you don't want to get hit and take damage. The room is outfitted with a series of ledges which collapse after Samus has stood on them for a period of time. Use them to your advantage, but find another place to stand once they collapse. They will reset themselves over time.

Once you destroy the Tester, you can proceed to the top of room O and pass through the door to room K. Room K will be much more heavily defended now with armored sentries. Head to the right, and bomb your way back into the passage that you originally took from room J above. Jump back up to room J, and roll along the passage until you are close to the door on the left. Bomb your way out of the passage, shoot the red door with a missile to access the Chozo statue in room I. Shoot the orb its holding to obtain the Plasma Beam. With the Plasma Beam in your possession, the armored sentries outside the room will be much easier to deal with, as the Plasma Beam passes right through their armor.
 * Clearing the Metroids

Item Gathering

 * Missile Tank A (room B): This tank is easily gathered in the bottom left corner of room B, although you may wish to wait for the lava to descend before you attempt to collect it if you don't want to take any damage.


 * Missile Tank B (room F): There is a tank hidden up in the ceiling of room F. To reach it, you'll need to find a spot along the left wall to begin using the Spider Ball.  Roll along the wall until you start rolling to the right along the ceiling.  Lay bombs down to discover one tile which bombs can destroy.  Then roll up into this passage to discover the tank.


 * Missile Tank C (room G): Along the floor of room F, you'll see a pit to the room below on the left side. Bomb the floor above this pit to gain access and drop down to room G.  Once inside, you'll need to roll around through very narrow passages in order to proceed to the right.  You'll have to bomb several blocks to proceed.  You'll spot the missile tank easily, but you'll be forced to go far to the right and then double back in order to collect it.  Find a passage that takes you back to the left and above the tank.  When you are as close as you could be above the tank, bomb the floor to break through and get closer.  The floor that the tank rests on will give way as soon as you touch it, so be ready to roll into the alcove and collect the tank before you are forced to drop down to the passage below.


 * Energy Tank A (room F): Read the procedure to collect Missile Tank C above. When you are in room G, continue all the way to the right side of the room.  When you reach the end of the passage where another pit opens up, jump up to arrive beneath the right side of the floor in room F, where the Energy Tank is waiting.
