Game Overview
Civilization has sunk beneath the waves. Gather driftwood and salvage to expand your raft into a floating base. Progress splits into two tracks: base simulation and auto-battling crew combat.
Gather Resources
Collect debris floating around your raft, or risk shark-infested waters on a salvage boat and diving expeditions to pull wood, metal, and food from sunken wrecks.
Build Your Base
Construct and upgrade facilities like water purifiers and fishing spots. Assigning crew suited to each job boosts production efficiency.
Crew Combat
Line up roughly five crew members to fight automatically. Formation and composition decide the outcome in stages, world bosses, and PvP.

Rerolling takes about 20 minutes. Here's the fastest route to unlocking the gacha, and which characters are worth holding out for.

Top Picks (SS)
Any of these four is worth stopping for. Between crowd control, tanking, buffs, and summons, each one anchors a different early team.
All Tiers
Best Characters
A power ranking based on investment priority. The axis is different from the reroll list above, so a few characters swap places.
Scrap Vulture Oliver
Heals the whole team and boosts the crit rate of your highest-attack ally. An all-round support that stabilizes the party.
Steelman Cole
Teleports to the back line and fires an energy wave three columns wide at the densest cluster of enemies. Broad-range damage.
Bouncy Bob
Wide-area taunt, plus roughly one-third damage reduction with the rest reflected back as a counter. Top-tier tanking.
Techhound Lee
Summons two robo-dogs that keep chipping away at the front line. A core pick for teams that want more bodies on the field.
Lizardman Curtis
A transformation skill widens his attack range — shines once fights turn chaotic in the late game.
Mechanic Girl Zoey
Summons a giant robot for sustained area damage. Pairs well with long fights and idle auto-battling.
Machine Butcher Silas
Forcibly yanks the farthest enemy into your side of the field, isolating their back line for a focused kill.
Neon Wizard Samuel
A buffer who raises attack speed and crit rate, and stuns enemies whenever their shield breaks.
