Details for this long-awaited horror game have finally emerged at The Grand Masquerade convention in New Orleans, and it looks like the MMO will be based on Vampire: The Masquerade.

We've known that CCP has been working on a World of Darkness MMO for quite awhile now. The company merged with White Wolf Publishing back in 2006, and they announced at the time that early development had begun to bring White Wolf's horror-filled universe into the online realm. For those of you unfamiliar with the World of Darkness, it's the setting for countless RPGs and novels that feature vampires, werewolves and other staples of the genre.

Well, some details have finally been revealed at The Grand Masquerade convention in New Orleans, which is being held throughout the weekend. Ardwulf's Lair (via Massively) is reporting that the MMO will indeed be called World of Darkness, but it is actually based on Vampire: The Masquerade, which is the older version of White Wolf's vampire RPG. (UPDATE: Ardwulf's Lair has confirmed through multiple reports that the game will be vampire-only, at least at first.)

According to Ardwulf's Lair, 2012 is the earliest release window for the game. World of Darkness "will have a focus on player politics and social interaction," which makes sense considering the setting. You can watch a trailer that consists of concept art after the jump.
