Peace Island is an adventure simulator with a third-person perspective and tells you how a cat named Elizabeth woke up one day in her house and discovered that her human owners were no longer there. There is silence around, there is no hum from cars, and the doors of the house are open. The cat immediately goes outside to find out what happened in the world and where all the people went, but sees only his own kind around him. The game features an open world and nine playable characters. As you progress, you will find new cats that you can switch to at any point in the story.
