3D GameStudio or 3DGS is a pan 3D computer game development system which allows the users to create 3D games and other virtual reality applications, and publish them royalty-free. It includes a model/terrain editor, a level editor, a script editor/debugger and comes with a big collection of textures, models and artwork, as well as a game template system that allows the creation of basic shooter games or RPGs without programming. For complex games or other applications, either the integrated programming language named Lite-C or an external development language such as Visual C++ or Borland Delphi can be used.
