The C4 Engine is designed by experienced industry professionals who know what a game needs. Before building C4, we worked on many shipping games for both consoles and PC, and you'll see every ounce of our wisdom poured into the engine's architecture. C4 delivers a comprehensive feature set and the rock-solid stability demanded by professional game studios.

C4 is an excellent engine for the modern game developer. The core framework exemplifies coherent software design structure that serves as a stable foundation for any real-time interactive application.

Development of the C4 Engine is led by Eric Lengyel, author of the best-selling book Mathematics for 3D Game Programming and Computer Graphics and regular speaker at the Game Developers Conference.

When the Professional Edition should be used

A license for the Professional Edition is required when either (a) you have a publishing agreement with a major publisher, or (b) you are developing a game for a console such as the PlayStation 3.

We define a major publisher to be any present or past member of the Entertainment Software Association (ESA) or the Entertainment and Leisure Software Publishers Association (ELSPA). Lists showing the current members of these organizations can be found at the following locations:

Important facts about the Professional Edition

The following list highlights the important points of the C4 Engine Professional License.

• You are permitted an unlimited number of engine users at your company.
• You receive additional support from us, including a private section on our forums.
• Your license applies to the development of a single game title, but that title can be published on all platforms supported by the engine.
• Once your title has been published, the Professional License reverts to a Standard License. You still receive updates to the engine (forever), but a new game title requires a new Pro License.
