Duality: Open-Source 2D Game Engine

A cross-platform game engine designed for quick prototyping, visual editing, and low-level rendering for advanced users, all within an open-source framework.

What is Duality?

Duality is an open-source, cross-platform 2D game engine and integrated development environment. It allows both visually-oriented designers and hardcore programmers to build games quickly and easily.

Some key features of Duality include:

  • Intuitive visual editor for quick scene prototyping
  • Modular systems for physics, graphics, audio, AI, and more
  • C# scripting access with CodeDOM compilation
  • Real-time preview mode to test games as you build
  • Content pipeline for importing assets like images, sounds, and fonts
  • Extensible plugin architecture
  • Cross-platform support for Windows, Mac, and Linux

Duality makes it easy for small teams and indie developers to create their own 2D games. The code is open-source and customizable, while still providing an accessible editor for designers. It bridges the gap between declarative visual design tools and raw, low-level rendering APIs.
