Urban Dea is an HTML/text-based massively multiplayer online role-playing game created by Kevan Davis. Set in a quarantined region of the fictional city of Malton, it deals with the aftermath of a zombie outbreak. Players enter the game either as a human survivor or a zombie, each with different abilities and limitations. Humans become zombies when they are killed, while zombies can be "revivified" with appropriate technology, becoming human. There are no non-player characters in the game: all humans and zombies are controlled by players.
