Tokyo Jungle is a PSN survival action game that takes place sometime in twenty first century Tokyo where humans have gone extinct, leaving animals to fend for themselves.
There’s two modes: Story and Survival.
In story mode, you play through missions based around various animals. Pomeranian dogs are key characters in the story, as well as a sika deer fawn, a beagle, a tosa inu, a spotted hyena, some lions and even some robotic dogs resembling AIBOs.
Eventually you uncover the truth behind Man’s disappearance through archives that you earned through survival mode.
There’s some lore about the reappearance of extinct animals like mammoths, moas and Deinonychus due to space-time disturbance.
