Enabling seasoned Unity creators to build more ambitious games

Unity powers a large majority of games on the market, many of which do not need ECS to be built. ECS for Unity brings value to seasoned Unity creators who need additional control and determinism to achieve more ambitious games.


An optional framework compatible with the GameObject ecosystem

ECS for Unity offers streamlined workflows and a familiar authoring experience in the Unity Editor, compatible with GameObject ecosystems. Creators can leverage their existing Unity expertise and assets to focus on creating ambitious games.

Game code based on ECS can quickly adapt to major gameplay changes

Game code based on ECS helps development teams quickly absorb important gameplay changes by eliminating most of the refactoring that would have been necessary with object-oriented architectures.


Game code based on ECS provides complete control and determinism

ECS for Unity provides memory control and determinism by design, creating optimization opportunities at scale, and new game code possibilities based on determinism. ECS for Unity is a C# package distributed with source code, allowing users to explore, debug, and extend it.


Best use of hardware with Burst, the C# Job System, and ECS game code

Game code based on an ECS architecture pattern can avoid the drawbacks of object-oriented programming with GameObjects. And by leveraging game code based on ECS, Burst Compiler, and the C# Job System, development teams can maximize the performance of target platform hardware resources at the memory and CPU level.
