In 2012, canines have rebelled against the humans. they were tired of being treated and regarded as nothing more than 'pets'. So the canines started a revolution.
They began defying humans and did what they pleased. The humans were terrified and because of the large quantity of dogs taking to the streets, now refusing to live indoors with the humans, they had to resort to hiding underground and living below ground while their once seemingly docile pets, roamed free and now were ruling. The humans no longer owned their own world. They were merely existing in it.
It's now a dog eat dog world. Do you have what it takes to live and thrive here? Or will you just fade away into memories of the past?
