💡 Quick Tip: Start by claiming all active codes for free Star Fragments, then check your race tier before diving in.

🎮First Steps

  • Swimming: WASD to move, Space to ascend, Shift to descend
  • Fishing: Click to shoot harpoon, aim for the fish
  • Oxygen: Watch your oxygen bar — return to surface before it runs out
  • Selling: Return to surface and sell fish at the dock

Visit the Codes page to get all current active codes. Star Fragments are especially valuable for rerolling your starting race.

🎲Understanding Your Race

Your race provides passive bonuses and abilities. Check the Tier List to see how good your race is.

❌ D-Tier: Definitely Reroll

These races provide minimal benefits. Use Star Fragments to reroll immediately.

⚠️ C-Tier: Consider Rerolling

Playable but not optimal. Reroll if you have extra Star Fragments.

✓ B-Tier or Higher: Keep It!

Good races that will serve you well. Start playing!

  • Vampire Squid (S-Tier): Recovers oxygen while fishing — perfect for beginners
  • Sea Angel (S-Tier): Extra oxygen and speed bonuses
  • Dolphin (A-Tier): Speed boost helps with travel time
  • Turtle (B-Tier): Extra oxygen capacity for longer dives

📈Early Game Progression

Phase 1 Goal: Earn $2,850 to buy Pufferfish Tube — this unlocks the Ancient Sands biome.

  1. Fish in Forgotten Deep biome (0–100m depth)
  2. Target Cod, Salmon, and Tuna (good value/weight ratio)
  3. Stay at 30–50m depth for safety
  4. Make multiple short trips rather than risky deep dives

Phase 2 Goal: Earn $1,050 to buy Advanced Gun — your DPS will double.

  • Now you can access Ancient Sands (100–200m)
  • Target Swordfish and Marlin (higher value)
  • Fishing becomes much faster and more profitable

💡Essential Tips

🫁 Oxygen Management

Always leave 20–30s oxygen as emergency reserve. Use the Oxygen Calculator to plan dives.

💰 Money Making

Target fish with good value/weight ratio. Hunt for mutations — even 2x doubles your profit.

🎯 Combat Tips

Lead your shots — aim where the fish is going. Larger fish have more HP, be patient.

⚠️ Common Mistakes

Don't dive too deep without proper equipment. Don't ignore your oxygen bar.
