Simulation code based on an ECS architecture pattern can scale to an unprecedented amount of entities, and ensure determinism within architecture. ECS for Unity provides Unity Physics, a stateless, robust out-of-the-box ECS-compatible physics engine that is ideal for multiplayer use cases.

For complex productions needing a AAA production-proven Physics engine, ECS for Unity powers the availability of Havok Physics for Unity. Havok Physics for Unity exclusively available and included for Pro, Enterprise and Unity Industry users.

Check out our session with Kasedo Games to learn how ECS has helped to power heavy NPC simulation for IXION, a city-builder based in space.
