After you activate a number of Thermal Devices while avoiding the E.M.M.I. in Cataris, you reach a shuttle to Dairon.

Activate a Device

Go to the left to reach the exit from the shuttle area. Go through the door. Jump up onto the blue wall on the right and climb up. Land on the flat platform at the top, then go to the left until you are near the left wall. Shoot the blocks below you and fall down through where they were. Drop down to the right, then go left to reach the bottom of the area. There is an Energy Recharge Station to the right that you can use if you wish. Then go through the door on the left to reach the Save Room. Save if you wish, then go through the door on the left.

Go to the left and drop down to the platform below. Watch out for the machines that launch sawblades at you. Make your way downward through the area. At the bottom, go to the right to fall through pitfall blocks. Go to the left to reach the next room.

Jump up onto the ledge to the left, then keep going left. Beware of the laser turrets and the flying creatures that shoot spikes in eight directions around them. Go to the left side of the room and go through the open door at the bottom. There is an inactive Total Recharge Station that can't be used right now. Go to the left side of the room and go through the open door there.

Go left and then up onto the ledge above you, and keep going upward through this room. At the top, go to the left and down. The door on the left is closed, but shoot at the floor to open a new path. Go down past where the blocks were, then slide through the gap to the left.

In the next room, go to the left and stand on the glowing panel to activate the machine, which will turn the electricity on in the area.

Get an Item Sphere

Go to the right and up the ledges to reach the door at the top that you can now open. Go through.

Go to the right and up to the top of the area. Go right from there until you reach a door with a missile cover on it. Shoot it with a missile and go through.

Slide through the gap to the right, then shoot the sphere that the statue is holding, and jump onto the item to acquire the Wide Beam. This changes your beam to shoot three beams simultaneously. This will allow you to open certain doors that could not be opened before, and will allow you to push certain barriers out of the way.

Reach the E.M.M.I. Zone

Go down and to the left, and shoot the floor to reach the lower area, then shoot the walls on the right, and shoot the ceiling on the right side, and go up to the Wide Beam Cover on the door on the right. Shoot the Wide Beam Cover to get rid of it, then go through the door.

Go to the right side of this large room, where there is a Wide Beam Box. Shoot it with a charged shot to push it to the right. Now you can jump up onto the platform above you. Make your way up to the highest platform, then go to the left and jump over the gap to reach the platform on the left. Shoot the red thing in the wall to give yourself a shortcut. Then jump up onto the ledge above you. Go to the left and go through the E.M.M.I. Zone Door.

Dairon E.M.M.I. Zone, Part 1

Go to the left while shooting your beam to get the walls out of the way. At the end, jump up onto the ledge. There will be a cutscene where an E.M.M.I. appears, and sees you, but you trigger a pressure plate that closes a shutter between you and the E.M.M.I.

Go to the right, jump up to the door on the right, shoot it with a charged shot, and go through.

Go to the right, and don't walk on the yellow floor. It's a pressure plate that will close a shutter in front of you. Instead, jump onto the ledge above the pressure plate, then continue going right to reach an exit from the E.M.M.I. Zone. Go through.

Return to Cataris

Shoot a charged shot at the Wide Beam Box to the right of the E.M.M.I. Zone exit. Then go through the door on the right to reach the Save Room you were in earlier. From the Save Room, go through the door on the right.

You can use the Energy Recharge Station if you wish. Then make your way up through the room, and climb up the blue wall on the right. You will reach another Wide Beam Box. Shoot a charged shot at it to get it out of the way. Then to the right and go through the door there to return to the shuttle area. Stand on the glowing platform in front of the shuttle to return to Cataris.
