Product Overview
What is Summer Engine?
Summer Engine combines game development, publishing, and live operations in one platform. Creators can build editable 2D and 3D games with its built-in assistant or external coding agents, while developers retain control through C++ and C#. Asset creation, managed multiplayer, publishing tools, and gameplay analytics help teams move from an initial concept to a released game and ongoing updates.
Key Features

Asset Library and Creation
Access over 175,000 free assets, including models, textures, and sounds, or generate new assets in Summer Studio.
