What Is Unity Game Engine?

Unity is a cross- platform game engine used to create 2D and 3D games, interactive experiences, VR, and AR content. It was first announced and released in June 2005, and it is especially popular for mobile and indie game development.

Quick Scoop

In simple terms, Unity is the software framework developers use to build the game, while the engine handles many technical parts behind the scenes, like rendering graphics, physics, animation, and scene management. Unity uses a component-based system, where game objects get behavior through components and scripts, and C# is its primary scripting language.
