Deeeep.io

Deeeep.io is an underwater IO game where you play as a marine creature, eat your way up the food chain, and fight for dominance in a 2D ocean ecosystem. Start as a tiny shrimp, end as a great white shark or giant squid.

How to Play

Navigate the ocean with your mouse, eat food (plants, smaller fish, plankton) to gain XP, and evolve into bigger creatures. Different creatures have different speeds, abilities, and diet requirements. Stay near your food source and away from predators.

Controls

• Mouse — move
• Left click / W — boost
• Right click / Space — use creature ability
• Shift — surface-breathing creatures use air

Creatures

Dozens of animals across different tiers:

• Tier 1 — shrimp, plankton, tiny fish
• Tier 5 — piranhas, electric eels, seahorses
• Tier 10 — sharks, whales, octopus, giant squid, T-Rex, dragons

Each creature has unique abilities — octopi ink, electric eels stun, sharks have blood-sensing.

Biomes

• Open ocean — general mid-tier action
• Shallow water — air-breathers dominate
• Deep sea — only pressure-resistant creatures survive
• Arctic — cold-adapted species
• Swamp — amphibians and freshwater fish

Tips

• Stick to your creature's optimal biome
• Learn each creature's ability — it often saves your life
• Don't chase boosting predators — they'll turn on you
• Breathe-air creatures need to surface — don't stay deep too long
• Team up with same-tier creatures for safer hunting
