The bay has had a going over.
New water. Light now moves across the shallows in shifting caustics, crests catch and glint as they turn, and the shoreline reads as water meeting land rather than a line drawn over it.
Jellyfish rebuilt from the ground up: real tentacles that curl, coil and drift, hanging from the original hand-painted bell.
Fish in your tanks now give way to one another. They ease aside and slow down rather than swimming straight through each other.
A new opening. Marina and Doc meet you on the dock together, and the first screen keeps out of your way until you have raised the shop.
Elsewhere: quicker drawers, a clearer Tank Shop, a tidier map, and a long list of smaller fixes to the HUD, pinch-zoom and story screens.
3.1 Aug 5
A whole new look, and new ways to dive!
3.0 Jul 30
New: the Calming Ring. Soothe each rescued fish by tapping and swiping in time with the music. Land taps on the beat, grab the stars the moment they appear, and swipe them home. Timing matters: perfect on-beat hits build a chain, and a clean run raises the fish's happiness and rehoming value.
New: Spirit Tide. A calmer camera minigame. Frame and capture the reef's spirit visitors for their portraits.
Other improvements:
- Flow combo, capture mastery, and daily streaks reward diving well and coming back.
- Field Camera for capturing the fish you meet.
- Equipment shortcuts: Gear up, Repair all, and auto-repair, so you spend less time in menus and more in the water.

Reef Rescue 2.0 is here, with 3D fish and a bottomless abyss that hides a mysterious presence...
THE FISH ARE ALIVE
Every fish has been rebuilt as a true 3D creature, and move much more naturally.
THE FATHOM TRENCH
A rare call comes in from the deepest water: an endless descent hiding a mysterious inhabitent. Can you reach them before your air runs out?
THE HUNT
Doc's Almanac now forecasts which rare fish surface in which conditions - dawn on flat water, storm swell, spirit-tide nights. Read the sky to plan your dive.
OTHER FIXES
- Your fish can now live indefinitely, and won't die of natural causes
- Species have preferences: schooling fish want company, shy fish want calm clean water, and the move-to-tank screen tells you where each one would thrive
- A Mailbox gathers letters from across the bay: Doc's field notes, the lightkeeper's scraps, visitors writing home, Corah on your battered gear
- The Chronicle keeps your history - every dive, birth, arrival and farewell
- Weekly market swings: someone is always paying over the odds for something
- Doc's research completes as you rescue, home and breed each species
- Fish now cast shadows through your headlamp beam during night dives
- Music and sound-effects sliders, plus a Power Saving mode
- Smoother harpoon aiming that follows your draw
- Buttons on smaller screens can no longer scroll out of reach
- Many fixes across the bay
Happy diving.

1.5 Jul 16
Dive after dark! Night dives now come with a diver's headlamp - sweep the beam through the black water and see only what you light.
New beneath the waves:
- Spare air tanks hide across the reef - swim onto one to top up your O2 and stay down longer
- A fine mist of silt drifts with the current, so you can read the water
- Volcanic sites now shimmer with rising heat
A huge performance upgrade under the hood:
- Brand-new rendering engine with 120Hz support on ProMotion displays
- Faster dive loading and much lower memory use
- Smoother scene transitions and audio crossfades throughout
New in Settings:
- Music and sound-effects volume sliders
- Power Saving mode (caps at 60fps and reduces effects to save battery)
- An optional FPS counter
Plus small fixes across the bay. Happy diving!

New this update:
• Doc's Almanac - a tide, weather, and day/night forecast in the Journal, with countdowns to the next Spirit Tide and festival.
• Dive debriefs - every dive now earns a grade and score from Marina, with a dive log and per-site personal bests.
• The Second Call - push your luck mid-dive for a bonus haul.
• Rehoming letters - the fish you rehome write back from their new homes.
• Guestbook - daily visitor reviews of your Sanctuary.
• Bloodlines - wild fish can carry colour morphs that pass down through breeding, with a lineage view.
• A relic log in the Journal for keepsakes recovered from the deep.
• A hidden keeper to find out on the water after dark.
Fixes & polish:
• Redesigned dive success screen and a fresh, bluer look throughout.
• Leviathans now break off and circle back instead of pinning you after a hit.
• Storms pass more quickly.
• Layout and stability fixes.
1.3 Jul 14

Plus everything from the Harbour Radio update:
• Marina, Corah, Doc and Silas radio in to introduce each part of the game right when it matters.
• Better diving: smoother movement, a wider view at speed, and skittish fish can be stalked by drifting in slowly.
• Ghost-net dives rebuilt, with major stability fixes and much lower memory use.
• Move, rename and rehome fish straight from their card; Buyer’s Board orders jump to a matching fish.
• In-game cash now shows a banknote icon everywhere, and landscape layouts for the dispatch screens.

The Harbour Radio update!
• Meet the islanders properly: Marina, Corah, Doc and Silas now radio in to introduce each part of the game right when it matters.

• Ghost-net dives rebuilt: lovely tiled rope, no more pop-in, and major stability fixes.
• Aquarium upgrades: move fish between tanks, rename them, and rehome them straight from their card. Tapping a Buyer’s Board order jumps to a matching fish.
• Clearer money: in-game cash now shows a banknote icon everywhere.
• Landscape layouts for the dive dispatch and cleanup planning screens.
• Smoother music crossfades between scenes and much lower memory use — fixes crashes when starting a dive.
