City of Heroes

City of Heroes (CoH) is a massively multiplayer online role-playing computer game based on the superhero comic book genre. In the game, players create superhero player characters that can team up with others to complete missions and fight villains belonging to various gangs and organizations in Paragon City and its surrounding areas.

Paragon City, the city in which the game takes place, is divided into different zones by giant energy walls known as "war walls". In story terms, the walls are used to prevent large scale attacks upon the city and to prevent high level enemies from entering low level areas. Zones are usually connected by road tunnels, but transportation such as the monorail, ferries and helicopters is also provided. Especially dangerous zones called hazard or trial zones, which teem with large groups of enemies, are connected by passages in the war walls guarded by the police and access is restricted to heroes with a minimum security level.

Many enemies are found on the streets of Paragon City, whereas others are found in specific instances or areas. There are also Giant Monsters and similar events that take place in parts of the city that are even rarer, such as Lusca the Giant Octopus in the waters of the Independence Port zone or the Ghost Ship that spawns ghostly enemies in the Talos Island zone as well as the Independence Port zone.
