S2 Engine 1.5.5 is a complete kit for developing games and Virtual Reality environments.

One of its best features is high quality of graphics subsystem based on a technology that allows to project shadows over any surfaces and any objects in scene apart from their position and/or complexity.
Moreover S2 Engine has a flexible modular structure that allows user to implement new features (such as: curved surfaces, particle systems, dynamic LOD, new shaders, new deformers, etc.) and porting the code to other systems like, for instance, consoles.
