Lionfish Reef Heroes

Dive into Lionfish Reef Heroes, an underwater arcade adventure where quick reflexes, careful aim, and a better dive kit help you go farther. Hunt invasive lionfish, protect native wildlife, explore colorful ocean habitats, and take on marine research missions.

Your next dive could bring a rare creature, a dangerous predator, a powerful relic, or a boss standing between you and your next checkpoint.

EXPLORE TEN OCEAN HABITATS
Swim through sunlit coral gardens, seagrass nurseries, towering kelp forests, shipwrecks, open water, and glowing deep-sea environments. Venture into Jurassic Sea, Crimson Bloom, Opal Atoll, and The Black Descent, each with its own wildlife, scenery, and hazards.

MASTER THE DIVE
Hold to rise, release to sink, and aim your spear at lionfish while sparing reef fish, turtles, and rays. Collect air, dodge mines and jellyfish, ride shifting currents, and escape charging predators. Build catch streaks and choose upgrades during your run to keep the adventure going.

FACE OCEAN BOSSES
Take on encounters including The Coral Crown and Ironveil Kraken. Read attack patterns, find openings, and land your shots to clear the way forward.

BUILD YOUR DIVE KIT
Earn coins and find treasure chests, discover equipment across five rarities, and combine items to suit your play style. Upgrade your spear, air tank, suit, and collection range. Equip relics with abilities such as chain lightning, protective shields, and slowing nearby threats.

DISCOVER A LIVING OCEAN
Watch schools of fish, gliding rays, crawling crustaceans, and other animated marine life. Encounter rare animals, record discoveries in your Ocean Journal, and learn which creatures to protect and which hazards to avoid.

TRY FIVE MARINE-CAREER MISSIONS
Unlock Research Station assignments as your diving career grows:
• Plant nursery coral and survey your work.
• Photograph and identify reef wildlife.
• Assist with sea turtle care in a guided simulation.
• Collect and label shoreline samples.
• Identify and measure fish as a fisheries observer.

Explore reef sites and the Atlantis and Big Dawg wreck areas during selected assignments.

MAKE EVERY DIVE COUNT
Complete contracts, earn achievements, advance through career ranks, and improve your personal records for distance, reef score, and lionfish catches. Even a short dive can bring you closer to your next upgrade.

FIND YOUR OCEAN RHYTHM
Enjoy colorful pixel art and an original soundtrack, with music volume, playlist, and repeat controls. Start with an interactive training dive, then put your skills to the test.

Gear up, watch your air, and become a reef hero.
