5 Ocean Zones · 5 Zone Bosses · 8 Gun Modes · Full Combo System
Everything you need to dominate the abyss and top the leaderboard.
Goal: Dive as deep as possible, collect gems, defeat enemies, and survive before your O₂ (oxygen) and HP run out. Kill each Zone Boss to unlock the next zone!
Energy System: Both Boost and Dive use energy bars that refill automatically. You can always keep diving — just manage your O₂ separately.
Zones unlock based on time played, but you must kill the current Zone Boss before advancing. Each zone has unique creatures, atmosphere, gem pool, suit, and boss.
Bright tropical waters with god rays, caustics, and colourful reef life. Easiest zone — great for learning the game.
Fires flaming balls in spread patterns. Kill to unlock Zone 1.
HP: 400 | Boss Damage: 40
Deep blue-purple waters with bioluminescent orbs and filtered surface glow. Enemies are faster and smarter.
Fires electric pulses in ring patterns. Enrages at 40% HP!
HP: 500 | Boss Damage: 50
Near-black waters with anglerfish lures and green bioluminescent creatures. Anglerfish attack pattern and red eye flashes appear.
Charges + fires venom. Spread shot in rage mode!
HP: 650 | Boss Damage: 65
Dark red-black abyss with crushing pressure ripples and lava seep. Marine snow falls through total darkness.
Ink spray + tentacle attacks. Full ring shot in rage!
HP: 800 | Boss Damage: 75
Hydrothermal vents, volcanic sulfur particles, glowing mineral crystals. The ultimate challenge with homing projectile boss attacks.
Homing lava balls + scatter shots. Hardest boss in the game!
HP: 999 | Boss Damage: 90
Each zone has one Zone Boss that spawns at 75% through the zone timer. You cannot advance to the next zone until you kill it. All bosses have two phases — normal and 💢 ENRAGED (below 40% HP).
Every Zone Boss gives +500 bonus score on kill. They also guaranteed drop a random gun power-up! The boss kill unlocks the next zone immediately.
Gems spawn near your camera position. Each zone has its own gem pool — deeper zones give more points. There's also a rare 💫 gem (12% chance) worth bonus points in any zone. Combine with the Combo system for massive multipliers!
Power-ups spawn randomly and float near your position. Collect them by swimming into them. O₂ and Energy power-ups have higher spawn priority to keep you diving!
Restores +40 HP instantly. Critical when taking heavy damage from bosses.
Refills +45% Oxygen. Higher spawn weight — always look for these to stay alive longer!
Blocks the next hit completely (6 seconds). Essential during boss rage phase. Blocked hits refresh partial shield!
Increases movement speed by 1.55x for 5 seconds. Great for dodging boss patterns.
Attracts all gems within 200px radius for 6 seconds. Massive combo builder!
Instantly refills O₂ to 100%! The rarest and most valuable survival pick-up.
Fully refills both Boost AND Dive energy bars instantly. Great for rapid zone escape.
You start with the Normal Gun. Gun powers drop from killed enemies (22% chance) or are guaranteed from Boss kills. The gun auto-upgrades every few minutes as a free temporary boost. Powers last 15 seconds when picked up.
Even without pickups, your gun upgrades automatically as you survive longer:
Collect gems consecutively without stopping to build a combo multiplier. The multiplier applies to the current gem's points. Combo resets after ~2.3 seconds of not collecting.
Example: Zone 4 Lava Gem (150 pts) at x10 combo = 1,500 pts! — Use the 🧲 Magnet power-up while comboing!
The game gets harder over time automatically — no separate difficulty setting needed. Three phases scale enemy speed, damage, O₂ drain, spawn rate, and energy regen.
| Phase | Time | O₂ Drain | Enemy Speed | Enemy Dmg | Spawn Rate | Energy Regen |
|---|---|---|---|---|---|---|
| EASY | 0–15 min | 0.008/tick | 0.65× | 0.65× | 0.5× | 1.6× faster |
| MODERATE | 15–40 min | 0.013/tick | 1.0× (base) | 1.0× (base) | 1.0× (base) | 1.0× (base) |
| HARD | 40 min+ | 0.018/tick | 1.45× | 1.45× | 1.6× | 0.75× slower |
Additionally, mini-bosses (🐳 Whale, 🦈 Shark, 🐙 Octopus, 🦑 Squid) randomly spawn in Zone 2+ at 6% chance per enemy spawn, making late-game zones extremely dangerous.

Pick up a Shield power-up and save it for when the boss goes below 40% HP. The rage phase fires nearly double the projectiles — one blocked hit can save your run.
Activate the Gem Magnet in Zone 4 with a running combo. Zone 4 gems give 120–160 pts each. A x10 combo on a 160-pt gem = 1,600 pts in one collect!
Use Laser Beam normally (fast, piercing, good DPS). Switch to Explosive or Sniper when the boss rages — you need high burst damage before getting overwhelmed.
When 5+ enemies are on screen, Freeze Gun slows them all to 30% speed. Use it to collect gems safely and reposition before switching back to a damage gun.
During boss fights, quickly Dive downward to change your Y position. Boss projectiles fire toward your last known location — a quick dive can make all shots miss.
O₂ bubbles automatically float up through your path. Prioritize grabbing them over gems if your O₂ drops below 30%. Dead = 0 score. Alive = more score!
The Dive and Boost bars refill automatically. Don't hesitate to use them — especially Dive during enemy swarms. Rapid direction changes make you very hard to hit.
On mobile, tap slightly ahead of a moving enemy's path — bullets travel to the tapped world position. This leads the shot and gets you more hits on fast enemies.
Hold Right Mouse Button while pressing Down/S to combine Dive + downward movement. This is the fastest way to descend and also earns depth score quickly.
