In this post, we will explain step by step what you need to acquire and where you need to go before heading to Kraid. To begin, you will start in Cataris after traveling back from Dairon. Head down through the EMMI zone, dodging the Green EMMI as you go. Move upwards and to the left until you get through the top- most door leading to the Central Unit. Defeat the Central Unit and use the Omega Beam to defeat the Green EMMI.
After defeating the Green EMMI, you will need to head down to the bottom left. Using Morph Ball, which was acquired after defeating the Green EMMI, squeeze into the small cut out on the left-hand side of the screen. You will make your way down a zig-zag tunnel. After falling out of the tunnel, head left. There should be another area to use Morph Ball. Follow this path. Once out, shoot out the fake blocks up on the left side. From there you will follow it until there, Morph Ball over to the left. You’ll need to jump up and grab the ledge to Morph Ball. Work your way up and use the Red Teleporter. This will lead you to Artaria.
In Artaria, you will need to head left. You will go through the save room. You may choose to save or not at this point. Head out of the save room, going left. There will be a Full Energy Recharge. Make your way upwards, Morph Ball, and head to the right. Follow that path, making your way upwards. You will go through the door and head to the right. You will find a Thermal Change Station. Change the direction of the thermal flow. Start running after you do this. The room will get hot quickly and begin to hurt you. Start heading upwards, following the path. Once at the top, head to the left and make you way out the top door. It will no longer be hot. (You will be able to go back through the hotter areas once you acquire the Varia Suit) Jump up and head through the door on the right. You will follow this stretch down until you can jump up again. This will lead you to the Varia Suit.
After you have the Varia Suit, head back down, only this time, head to the right. You will go back down through the area that just flooded with heat. Make your way back down to the Red Teleporter. Take it back to Cataris.
Back in Cataris, you will head down and to the right. Go through the heated zone, following it until you find a the door with a creature coming out. Defeat the creature and head through the door. You will battle Kraid here. After defeating Kraid, head up and Morph Ball to the right. You will go all the way to the right and loop back to the left. You will find Diffusion Beam. Use it to go up through the ceiling. Head to the right and work you way up to the Purple Teleporter. This will bring you to Dairon. This is where you will need to start taking steps to defeat the Yellow EMMI. Look at that post to find the instructions for that area.
