About Alien

ALIEN (Artificial LIfe ENvironment) is an artificial life simulation tool built on a specialized 2D CUDA particle engine for modeling soft bodies and fluid-like media. It enables users to create and observe digital organisms composed of interconnected particles, which can be equipped with functions ranging from information processing to physical components like sensors or muscles, and supports evolution simulations via a built-in genetic system. The software runs simulation and rendering on GPU, is available for Windows, and its interface and supporting materials are in German.
