About this game

Dive into Fish Swarm 3D: Crowd Run — the addictive underwater swarm game where one little fish becomes an unstoppable ocean army!

Start as a single fish and recruit hundreds of others into your swarm. The bigger your school, the more powerful you become. Crash into rival swarms, swallow them whole, and dominate every arena before the timer runs out!

🐟 HOW TO PLAY
Swipe to swim. Glide over white fish to recruit them into your swarm. When your school is bigger than an enemy's, smash into them to absorb their fish. Outgrow every rival and finish #1!

🌊 6 STUNNING UNDERWATER WORLDS
• Coral Reef — bright shallow waters
• Kelp Forest — dense green jungle
• Open Water — endless blue
• Deep Trench — glowing creatures in the dark
• Sunken Wreck — explore ocean ruins
• Graveyard — the eerie deep

Every level looks and plays differently, with a glowing volcano, sun rays piercing the water, and animated sea life all around you.

⚡ POWER-UPS & SHOP
Spend coins you earn in battle on game-changing boosts:
• Speed & Flash dash
• Shield

🏆 EASY TO START, HARD TO MASTER
Level 1 is a gentle warm-up. But every level adds faster, bigger, smarter rivals. How far can your swarm go?
