Year 2204, game takes place on a planet colonized about 10 years ago.

The planet is populated by humans, genetically modified animals by humans, and natural to the world flora and fauna. Before the landing there were no anthropomorphic animals: they were human test subjects, under whom experiments were conducted and over the years after landing they were transformed into something else.
Earthlings brought ultramodern technology with them, but over time, and given that the longevity of the equipment was only designed or sabotaged for flight to a new planet, advanced technology is everywhere, but almost none is still functional today. And while humans can't replicate cutting-edge technology, regression to pre-20th century technology is still possible.

The planet has its own independent flora and fauna, example of such is linked picture.
