Archaeologist Hidden Achievement
Beginner's Luck Hidden Achievement (Secret)
Eye of the universe in one loop.
NOTE: If you die at any point, you need to quit and start a new expedition again, this needs to be done in a single loop.
Acquire your launch codes from
Hornfels in the Observatory Launch your ship and head to
Ember Twin orbiting near the Sun Land near the Distress Beacon (bright blue light being projected into the air) and acquire that Signal by scanning it with your Signal Scope
Giant's Deep and take the tornado spinning counter-clockwise down to the Outer Core. Use a jellyfish to pass the electric barrier and enter the Inner Core.
Navigate to the probe tracking module and get the coordinates.
Hop back in your ship and fly to the
Ash Twin Land offset of the equator so your ship doesn't get sucked up in the sand and wait for the tower to be uncovered.
The tower we need to use is the broken roofed one of the twin towers found by following the bridge from the Sun Shaped tower.
Stand against the wall and look up, making sure you're underneath a piece of the remaining roof so as to not get sucked up into the sand.
Once the black hole teleporter (the purple square on the floor) is exposed, you are ready to teleport.
To teleport, wait until the sand has come around and is going directly overhead. As it passes over, step into the middle of the room and you will be warped to the core of the Ash Twin.
Once you've entered the core, run around the loop until you reach the orb switches, deactivate the shielding around the warp core and turn off the artificial gravity to grab the newly exposed core.
Maneuver your way back to the White Hole warp pad, leave the core and return to your ship.
Fly to Dark Bramble and enter it while searching for the Distress Signal; following the signal through the seed until you arrive at the source.
Turn around and follow the little light blocks until you reach a seed with a bunch of dead Nomai around it.
Shoot your Scout through the seed; it will land on
the Vessel. Then fly to the red light. Stop just outside the red light seed and get out of your ship, making sure your air and fuel are full.
Line up so you're not looking directly at any of the white lights and enter the seed.
You need to propel yourself very gently past the
Anglerfish and towards your Scout (1 arrow of thrust should be quiet enough). Once you reach the seed, you can fly fast into it and head straight for the Vessel on the otherside.
Enter the Vessel and head to the left in the hallway. Enter the bridge on the left to find where you need to place the warp core.
Place the warp core, move the orb switch to the code input device (towards the front of the Vessel) and then enter the code.
Once the code is entered and the code entry machine descends downward, grab the orb switch and pull it upwards and enjoy your achievement!
