How do you find the artifact of chozo?

Go to the “Transport to Tallon Overworld South”. Ride up the elevator and go through the door. Go through the tunnel and then through another door. Climb up the ledges and attach to the spider ball track. Drop off at the top and quickly grab on to the second part of the track. Ride that up and drop off on the ledge. Blast through the door. Power bomb the bendezium. Boost up the halfpipe and roll into the “Life Grove”.

But don't forget to get the missile upgrade. At the top of the second loop use a bomb and you'll end up falling down collecting it. Grab the X-Ray visor in the next room, then immediately use it. Power bomb this area from where you're standing to explode the walls. Go into the water and bomb the plug. Then use the newly opened spinner to reveal...the Chozo Artifact? What is this? Go back to the “Landing Site” to find out.

But how do you exit this area? Climb up the platforms and MB (morph ball) through the tunnel to get to the bridges. Leap about the platforms until...oh crap...3 Chozo Ghosts! Use the newly found X-Ray visor to target them indefinitely.

Get back up to the platforms and leap about until you get to the Chozo’s head and drop into the slot below it. Roll back through the passageway and through the door.
