What is NeoEngine?

NeoEngine 2 – Evolution is the second iteration of the game engine created by Reality Rift Studios. It is a modern object-oriended game engine written in C++, featuring all components needed to create a modern 3D game including subsystems for rendering, audio, physics, input, scripting and networking with a platform-independent API.

NeoEngine 2 – Evolution is currently ported to Windows, Linux and MacOS X, and runs on x86, x86–64 and PPC CPUs.
