Dive into four hundred years of technological progress in the underwater city of Royla, where humanity once found a new home. That is, until this future Atlantis was besieged by wild monsters mutated by toxic sea waste. Take on the role of the sea guardian Pronty and fight alongside your spear partner Bront to take down the mutants, uncover the truth behind the sudden invasion of the creatures, and unravel the secrets of Pronty's origins.

Game Features:

• Unique Javelin combat system: Control the inexperienced Pronty and Bront the Javelin, an armed robotic swordfish capable of fending off the toxic waste-corrupted sea creatures. Use Bront to repel enemies, clear obstacles, and protect Pronty from harm.

• Interchangeable upgrades for personalized combat: Unlock new abilities and upgrades on Pronty's memory board to develop strategies that suit every situation and play style.

• Challenge across all difficulty levels and Boss Rush mode: Replay the game repeatedly, with post-launch updates including the Boss Rush mode in Neptune's Hall.
