Conference of the Four Main Mission Guide

To start the mission, open up Baker and read Gilberta's message. She asks if you're around and you could come to the Hub Base to help her with something.

Head to the Hub Base to meet up with Gilberta. Just to the left of the TP Point, you find her floating in the air while staring at a letter. She asks you to join her at helping deliveries.

You will enter a series of Delivery Challenges. Approach Gilberta and take the first package from her. The package needs to reach the canteen before mealtime.

For Delivery Challenge I, deliver the package to the canteen in the Hub Base before the timer runs out. Do not exceed the time limit or you will fail the challenge.

Head back to the Hub Base and take the second package from Gilberta. This time, the package needs to reach the Core AIC Area without a single dent or scratch.

For Delivery Challenge II, deliver the package to Andre in the Core AIC Area before the timer runs out. You cannot teleport to the area, so head there by foot and make sure to avoid combat to keep the package safe.

Return to the Hub Base again to take the third package and begin the last delivery challenge. This package is full of medication meant for the medical bay.

For Delivery Challenge III, bring the package to the medical bay in the Worker Dorms. Since the package is full of vials and bottles, you should avoid jumping or dashing as it will damage the package.
