Artificial Life Environment

Create a world, seed it with life and watch evolution take over.

ALIEN (Artificial LIfe ENvironment) is an artificial life simulator that runs millions of particles in real time on your graphics card. Its worlds are made of particles that bond into elastic bodies, flow as fluids or come alive as cells. Cells take on roles such as sensors, muscles, weapons and constructors, each steered by its own small neural network. Together they form creatures that move, feed, fight and build offspring according to their genome. Switch on mutations and the world evolves on its own. Lineages diverge, ecosystems emerge and new forms appear that nobody designed.

Step in at any time: draw matter, push creatures around, change the laws of physics or let an AI agent do it for you.
