FAI is the most powerful underwater AI system currently on the Unity Asset Store. It contains not only a system that can be used to simulate a broad underwater ecosystem (salmons, sharks, whales…) but also a powerful and deeply-optimized flocking system that can run +20,000 units at the same time at +100 FPS.
