Three days ago in the fictional city of Varrigan, a terrorist group called The Organizers planned to completely isolate the island from the rest of the world. They bring a virus capable of killing a person in less than a day. Facing this situation, the leadership of the city of Carrigan has recruited people who are likely to find a way to eliminate this virus. Transforming into a brave stand up against The Organizers and finding the scary virus to save people on the island, you will have to complete the task. MadWorld is divided into different levels representing different areas of Jefferson Island. Players are allowed to rejoin the levels they have passed, to be able to create new achievements (better than before). Most levels will allow you to explore freely but still have to complete some of the required tasks. Some levels will require players to fight, to control the enemy. To avoid boring the game, the mini-games have been added so it can simply shoot and kill certain bats, or control a speedboat in a certain space.
