"Processing facilities," which can earn money in exchange for resources,
"Commercial facilities," which residents can use to earn money.


Exploration is required to obtain recipes for new buildings, Mira's flower seeds, mysterious oparts needed to liberate the story, and area liberation items.
The objective is to board an exploration boat and wade through enemies and traps that lurk in the deep sea to obtain the items and to step over them.
There are three parameters for exploration boats: HP, air, and payload, each of which can be strengthened with money.
