The Isis Hotel

Items Checklist

• GaiaArm
• RobotParts
• MultiMissile
• MultiMissile
• MultiMissile
• MultiMissile

Sitting on an island just south of the port, this ruined hotel will probably be your first stop here (if you haven't been sequence-breaking...not that there's a firm order to this part of the game, anyway).

Cruiser Station

Items Checklist

• GuardKit

Barely even a dungeon on its own, but it has monsters, and it's got a treasure, so it qualifies for that much. Plus, it's your gateway to the rest of the dungeons in the region. Grab a cruiser and sail the canals.

Hospital Ruins

Items Checklist

• Calorie2K
• BPCharge3K
• Steroid
• MedKit
• RoboHP2K
• Rust-Off
• RobotParts
• RoboKit3

The in-game minimap has this place right on the transition line, so it's difficult to tell by looking there that it's only accessible via canal.

Library Ruins

Items Checklist

• Book
• Book
• Book

This library is also accessible from land, but split in half—the items are only accessible from the canal-side, while the recordings are only accessible from the land-side. Stop by here again when you're nearby at CornBase to check those out; they help elucidate the timeline of events leading up to the current situation.

Rec Center Ruins

Items Checklist

• SAMMissile
• Steroid
• IronPills
• BPCharge1K
• MatsuCapsule
• RoboHP2K
• Calorie2K

This place may be optional, but it's important. First, this is where you meet your final party member, Long. He's on the bottom floor, injured, carrying important materiel: a MatsuCapsule. You heard about those on Satellite Base, right? You can bring it to Dr. Matsushita, and he'll make you an EnergyPack, the best recovery item in the game.

Second, you can encounter the enemy Crystal Core here. Like the Transpealer earlier, they flee and are worth a ton of experience if you can defeat them before they do: 10,000 exp each this time. Unlike the Transpealer, though, the Crystal Core counts as a Mutant, so instead of Dennis's Crusher, Rita's Coolbeat will be more effective. Attack items are good, too.

CornBase

The Cyborg Unit is having their own troubles: they've been ransacked by the Iron Unit! How'd they get to Land 2? The shops won't be open here until you can deal with them.

Explore the base, there's lots of information to be gained. Gene will learn his new Super, Slam. And you'll meet Kazu's mother. She's worried about him, and gives you Kazu's Charm to give to him. Don't forget to stop by the Lookout the next time you're in Potatia!

The RKO guide recommends having everyone able to equip at least Rank 4 weapons before proceeding, if they aren't already able to. You will, of course, have to craft those.
