Vampires!
From The Urban Dead Wiki
Game by RavenBlack, a friend of Kevan's. Grid-based RPG which predates Urban Dead. (Vampires! is a development of Graaaagh!, and UD is a development of Vampires!, with permission.)
Be a vampire and suck the blood of humans, as well as other vampires.
The most visible differences between Vampires! and Urban Dead are the meme-like invite (lure people to a page to gain blood in game) and the single character 'race,' creating a different PVP environment.
