Breathe life into an empty void and watch as it grows, evolving into a world of your choosing. Your only goal is to create a complex ecosystem - it can be a brutal world of predators or a peaceful garden; breed an intelligent species capable of speech or a super-organism that will consume the stars. With HOUND, you make the world that you want. HOUND gameplay is simple: you start with an empty world, build your ecosystem, design your first organism and throw it into the void. HOUND's advanced artificial intelligence analyses your creation, finds it strengths and weaknesses, then gives it competition in your world. Watch as life evolves before your eyes - literally; the creatures exist in three dimensions, develop legs, wings and communication. Your organism will fight for survival, stimulating successful mutation and increasingly more complex life forms. Leave your new world for too long though, and the simulation will go out of control. Overpopulation, plagues or even a supernova explosion will turn your world into a wasteland… unless you fight back.
