The NAOS Engine™ (pronounced like "chaos") is a highly scalable, client/server game engine, designed to support a very large MMORPG. Continuously developed and refined for our own game, Vendetta Online, the engine has been proven through years of usage and expansion (public Alpha in May of 2002, retail game launch in 2004, and up to present-day). The game has over a million installs on Android alone, has been the subject of major television commercials, and was the first MMO to officially launch support for the Oculus Rift. Our engine client supports Windows, WinRT/Win8, Mac, Linux, iOS and Android™, with rendering drivers for DirectX (11 and 9), OpenGL and OpenGL ES 2.0. The server is intended for distributed use across a cluster running FreeBSD or Linux, and has been elastically implemented on Amazon EC2. We are currently in the process of making this engine available as a licensed middleware product.
