|City of Sin|
City of Sin takes places in what appears to be an abandoned city.
Judging by the texture entries in the map file itself, it seems that this map was developed by Gearbox Software. It has seemingly not made any media appearances, which might indicate that it was designed later during their development on the title.
- A version of the map has been leaked and is available for download.
- In Counter-Strike Online, there is a New Zombie Shelter map called City of Damned which is based on this map.
