Below is our walkthrough for Chapter 3 of The Gunk! Objects that you can scan for the encyclopedia are in the pinky purple font color! Remember that if you scan all the available items in The Gunk, you’ll earn the Space Archeologists achievement! Please also pick up all the materials that you find as you explore the area. You’ll need these materials to unlock upgrades for Pumpkin (your hand device). If you obtain all the upgrades, you’ll receive the All In achievement!
Once you gain control of your character on the ship at the beginning of Chapter 3, upgrade your device, specifically acquiring the Pulse Cannon upgrade, then approach the beacon to trigger a cutscene. Afterwards, interact with the beacon and travel to the Alien Ruins. Jump down and head to the large door in front of the tablet. Hold LT and press B to shoot a plasma pulse at the yellow dot on the top part of the door. This will cause the door to open! Enter the Ancient Ruins and press forward until you reach a locked gate. To open this gate turn around to find a yellow dot and fire a plasma pulse at it.
Defeat all the Gunk Critters and slurp up the goo around the pipe. Follow along the pipe until you reach the dead end. Beneath the archway under the pipe you’ll find a Mycelium Coil.
Grab it and place it on the Energy Fissure to cause a mushroom to sprout. Jump on it to continue forward. After you reach the new area called Polluted Lake, hug the right wall to find and scan a Mulligan Melon. Don’t pick it up quite yet as it explodes!
Instead, continue forward a short ways and scan the Rubble!
Return to the Mulligan Melon and use it to remove the Rubble. Continue forward to trigger a cutscene concluding Chapter 3!
