Your sub auto-dives, collects loot, and surfaces to sell. You don't pilot it β you upgrade it.
Tap the boost button (or press Space) for +200% speed and pickup rate. Tap again while active to add +1 second, up to a 10s cap. Cooldown starts after it ends.
Spend cash to upgrade Hull, Thrusters, Cargo, Sonar, and Appraiser. Levels are permanent within a run, but reset on Promotion.
Items collected this dive show in On Deck. Every encounter β bonuses (Lucky Current, Mermaid's Kiss, Treasure Map) and the Shark Attack hazard β comes from the Salvage Slot.
The slot in the corner auto-pulls every 15s. Triple matches: π Lucky Current (every pickup doubled, 15s), π§ Mermaid's Kiss (2Γ value, 15s), πΊ Treasure Map (legendary picks at 10Γ value, 15s), π Jackpot (all three, 30s). π¦ triple = Shark Attack (no loot for 10s).
Bronze/Silver/Gold chests spawn occasionally. Click to add to your tray (next to the cash). Open them whenever β multi-item rolls biased toward higher rarity.
Hit a tier's level threshold to promote (Deckhand β Salvager β β¦). Promotion banks pearls based on your run's lifetime earnings and resets level/cash/upgrades. Each pearl is +0.5% loot value, forever. Push deeper before promoting to bank more.
Achievements unlock as you play but aren't free β open the Honors panel and click each one to claim its cash reward.
Tracks every unique item you've ever salvaged. Empty slots are still out there.
