Deliver the Medicine Package to the Worker Dorms Infirmary

Deliver the Medicine Package to the medical staff in the infirmary at the Worker Dorms.
Challenge 3: No Jumping or Dashing

For the final package, you are prohibited from using Jump or Dash. The time limit is shorter at 1 minute, so plan the most direct route possible.

During the conversation with the medical staff, you will be asked to look for a girl named Carly. Use the Scanner to follow her tracks and find Carly inside the Worker Dorms.
Head to the Filter in the Power Plateau

Talk to Ropp, a researcher currently receiving treatment in the Infirmary, then head out to locate the Filter in the Power Plateau.
Use the Scanner to Destroy the Blight and Proceed

Talk to the person in charge at the Power Plateau to enter the Corruption Area. Use your Scanner to destroy the core of the Blight and open the path forward.
Use the Scanner to Investigate 3 Locations

Inside the Corruption Area, use the Scanner to follow the blue light trail and investigate 3 specific locations. Find the bottle containing a note, then talk to Gilberta.
Warning: Long Duration Event

From this point on, you will be unable to return to the exploration area for approximately 30 minutes. Prepare for a sequence involving exploration and Combat.
Follow the Guide While Defeating Enemies

Defeat the Landbreakers that appear and continue following the guide.
Enhanced Jump Ability

Gilberta will enhance your Jump ability, allowing you to proceed via simple parkour sections. Don't worry if you slip, as you can retry immediately even if you fall.
Find the Filter and Return to Ropp

Once you investigate the Filter, your objective in this map is complete. You will be transported back to the exploration area. After the conversation ends, return to Ropp in the Worker Dorms Infirmary.
Talk to NPCs in the Worker Dorms to Advance

To find clues about the "Maisie" that Ropp mentioned, talk to the people in the area. Afterward, meet up with Andre and talk to Ropp, who has now regained consciousness.
Talk to Gilberta to Finish

Meet up with Gilberta deep within the Power Plateau to receive a letter. Inside, Gilberta's true feelings are written. Reading this concludes the event.
