After you destroy the purple E.M.M.I. in Ferenia, you proceed to the Hanubia E.M.M.I. Zone.

Reach the Hanubia E.M.M.I. Zone

Go through the door to the left of the elevator, then go to the left side of the room, using Screw Attacks to kill the robot, then get on the ledge on the left. Use the Grapple Beam to open the tunnel if you did not do so earlier, then roll through it and go to the right side of the room, and Screw Attack upward to break through the rightmost block of the ceiling. Roll through the tunnel above that.

Go through the door on the right and there will be a cutscene. Afterward, go through the E.M.M.I. Zone Door on the right.

E.M.M.I.-07PB (Orange E.M.M.I.)

Screw Attack to the bottom right of the room and go through the door there. Go to the right and the E.M.M.I. will detect your movements. After a moment, there will be an explosion, and you will be stunned. You can't avoid the E.M.M.I., so you will have to perform a Melee Counter when you see the flash. However, the timing is not difficult like in the previous encounters. After you successfully perform the Melee Counter, there will be a cutscene, and a Chozo Soldier will attack.

Afterward, you will acquire the Power Bomb ability. In Morph Ball form, hold R to charge up, and when fully charged, press Y to set a Power Bomb. It will destroy enemies, and Power Bomb Blocks, and afterward it will pull ammo and health to the location where the bomb was placed.

Get a Power Bomb Tank

Go through the tunnel that opens up on the right side of the room, then go to the right and go through the E.M.M.I. Zone Door there. At the bottom right, there is a Total Recharge Station. Use it if needed, then get into Morph Ball form and hold R to charge up a Power Bomb. It will destroy Power Bomb blocks in the ceiling. Screw Attack up through the room and go through the E.M.M.I. Zone door at the upper left.

Detonate a Power Bomb to break open a hole above you. Go up through it, then go to the upper left of the room, and roll through the tunnel there. Screw Attack to the hole in the ceiling and roll through the tunnel there.

In the area where you land, the floor below you is made of bomb blocks. Use a Power Bomb to destroy them, or if you ran out of Power Bombs, use a regular bomb to break through the floor beneath the upper right tunnel, then get into the tunnel on the left side of the room and use a bomb to break a hole above you. Then go through the E.M.M.I. Zone Door on the left.

Shoot open the door on the left, but don't go through yet. There is a Power Bomb Tank that you can get beyond this door, but if you don't make it, the door will close behind you. There is another way to get it after that, however. If you want to try to get the Power Bomb Tank now, Speed Boost through the door on the left, and then, near the left side of the ledge (to the right of the machine in the background), ready Shinespark and drop a bomb, then press B and tilt down on the left control stick to Shinespark down through where the bomb blocks were, and you will destroy some Speed Booster Blocks.

Then go through the door on the left to reach the network station. Stand on the glowing panel to get a briefing and save the game.

If you didn't get the Power Bomb Tank mentioned above and want to try again, go through the lower right door of the Save Room, slide into the gap on the right and use Cross Bombs to get through, go through the door on the right, use a Power Bomb to break open a path through the ceiling, then follow the steps to get the Power Bomb Tank.

Get a Missile Tank

If you want to go quickly to the next area, you can try a Speed Boost maneuver. If you don't want to try it, just go through the door on the left, detonate a Power Bomb, and Screw Attack upward through the room, and go through the wall in the upper left to break the Screw Attack blocks there, and skip to the next paragraph. If you do want to try the Speed Boost maneuver, then start Speed Boosting in the save room as you shoot the door on the left, then when you reach the middle of the tunnel, quickly ready a Shinespark and get in Morph Ball mode, then charge up a Power Bomb and press Y to place it, then immediately press B and tilt up on the left control stick to Shinespark upward through the hole that the Power Bomb breaks in the ceiling. You will Shinespark through some Speed Booster Blocks up above.

From the top of the room to the left of the save room, go to the right and open the door there. Screw Attack the robot until it is destroyed, then go to the right side of the room and use the Grapple Beam to destroy the block to the right. Roll through the tunnel. If you want a Missile Tank, slide into the tunnel on the right while shooting a missile at the start of the slide. If timed correctly, you will hit the missile block at the end of the tunnel, revealing the Missile Tank.

Golden Chozo Soldier

You can use the Total Recharge Station above that if you wish, then jump onto the ledge on the left, then jump onto the ledge above that and go to the right. Open the door on the right and go through.

A gold-armored Chozo Soldier will appear. Hold R throughout the battle to lock on, and press Y when possible, to shoot missiles at it. Or you can use charged shots and regular missile shots. If you perform a Melee Counter when it plants its shield, hold ZR, then hold Y, then tilt right to use Grapple Beam to pull the shield away.

When the soldier changes form, you may wish to shoot single missiles at it instead of using Storm Missiles, because of how quickly you need to dodge each attack.

Go to Itorash

Go through the door on the right and step on the glowing panel to go to Itorash.
