Cinq Ville's name goes unmentioned in both games, but is mentioned in the ZX Tunes (album), ZXA Tunes and the ZX GIGAMIX (album). In ZX Tunes, it is considered a country whereas in ZXA Tunes, it is considered a city. In ZX Gigamix its the subject of the soundsketch "Reconstruction of Cinq Ville", which takes place one week after the events of Mega Man ZX.

History
Cinq Ville is the place where a Model W fragment and the Model W Core were both uncovered by Guardians' first commander. In the past it experienced an energy crisis and suffered from never-ending Maverick raids. Cinq Ville was saved by Serpent, who's energy company Slither Inc. stepped up and fixed all these problems. Since that day, the people of Cinq Ville have been protected by Slither Inc.'s security force of mechaniloids. They consider the company president a genuine hero. President Serpent, however, has secretly been manipulating the Mavericks and has been actively causing the Maverick raids for the sake of reviving Model W and enacting Project Haven by using the people of Cinq Ville as sacrifices.

As part of this plan, the amusement park in Area H was attacked by Maverick ten years ago. The main characters of Mega Man ZX, Vent and Aile were visiting this park at the time. Both of them lost their mother during this attack. Since that time, the park has been abandoned and fallen under Maverick control. Likewise, many other areas of Cinq Ville have also been taken over by Mavericks to further Serpent's plan. This caused Cinq Ville to eventually be divided into two; the safe areas of "Innerpeace" in which there is no Maverick activity and the people are protected by the security force, and the dangerous "Outlands" in which Mavericks roam freely.

Despite this unstable situation, the people of Cinq Ville live peaceful lives, unaware that their peace is merely a facade put up by Serpent until his plan to sacrifice the whole country finally comes to fruition.
