Are there multiple cities in The Matrix Online ?
No. According to the Wachowski brothers the Matrix is one very big urban environment, so that is how we designed it. It really is quite huge.

The look and feel of the Matrix is quite important, how exactly did you implement this ?
Well, first off, the city really looks like in the movies, and so does the clothing. Players have a lot (really a lot) of options to change clothes and accessories. Dress your character the way you like, to make it look cool or tough. More options for clothing will become available over time when your character gets more experience. Really a lot of time has been spent on designing a whole selection of clothing accessories for the players to use in-game.
