After the world powers devastate the planet by using chemical and nuclear weapons, the surviving populous resorts to living in a state of anarchy. The streets are dangerous; they are populated by groups of violent street thugs and unthinkable mutations that derive from radiation.
Anarchy Reigns is a 3D brawler that takes place in the city of Altambra. The city is an open sandbox that can be explored with no restrictions. The missions, on the other hand, are divided into zones and can only be unlocked by earning points. The player must battle hooded thugs in bio masks, mutated creatures and even Government extermination squads to earn enough points to reach these areas. When enough points are earned, a green mission circle appears on the world map. Once you find the mission area, you can enter it by pressing the Select button.
