The sea is full of secrets, and every one of them has a trophy waiting for it. Some are quick dives, others will push your limits far below the waves. Here’s every achievement in Shelldiver and how to unlock it, no fluff or filler.
Built to Dive
Max out every skill to its full level. You’ll need plenty of shells, upgrades, and a steady grind through deep runs to finish this one.
Hammock Sleep
Find a hammock and take a rest after a long day of diving. You’ll unlock this once you use the rest interaction on the island.
100m Depth
Reach a depth of 100 meters. This unlocks naturally early on as you start exploring the ocean floor.
400m Depth
Reach 400 meters underwater. Requires better gear and a few upgrades to your oxygen and pressure resistance.
700m Depth
Dive down to 700 meters. Make sure your equipment is fully upgraded to survive the deeper current zones.
1000m Depth
Reach 1000 meters below the surface. This marks a big milestone for your diver’s endurance and skill.
Make a Friend!
Wave to a turtle on the island. Just walk up and use the emote interaction when near one.
Ultra Special Rainbow Jellyfish
Catch a rainbow jellyfish. It appears rarely in deep ocean zones, so keep your net ready when glowing lights start to pulse.
First 1M
Reach 1,000,000 shells. Collect loot, open chests, and keep diving for treasures until you hit the mark.
First 1B
Reach 1,000,000,000 shells. Keep farming deep-level zones or invest in upgrades that increase shell gain.
First 1T
Reach 1,000,000,000,000 shells. By this point, you’ll likely have top-tier gear and access to the richest regions.
First 1Q
Reach 1,000,000,000,000,000 shells. This is the ultimate grind, achievable through max upgrades and long-term farming.
Cleared Island
Earn every other achievement in the game. Once all tasks are complete, this unlocks automatically as your final reward.
Final Blurb
Shelldiver’s trophies cover everything from deep exploration to massive currency milestones. Most can be earned through natural play or via gb-proxy, but a few will test your patience and gear upgrades. Keep diving, keep collecting, and you’ll eventually clear the island like a true deep-sea veteran.
