Retribution is an adventure simulator with a first-person view in a sci-fi setting. At the beginning of the 24th century, the threat of extinction overtook humanity. A brutal war for resources and food has begun on Earth. But fortunately, the technological race of the Krillans visited our planet to teach us to live with them in alliance and not destroy ourselves. The guests brought a new wave of technology, unique medical knowledge and, most importantly, the wisdom of the world. Now you too have to go into limitless space and bring new knowledge to other races.
