Built using Valve's Source Technology - the same game technology used to power Half-Life 2, and seamlessly combining role playing with intense first-person action combat, Vampire: The Masquerade - Bloodlines allows players to become a dangerous creature of the night as they assume the role of a recently embraced fledgling vampire in the service of the city's dark prince. Vampire: The Masquerade- Bloodlines is being developed by Troika Games, whose founding members' credits include the award-winning Fallout, and is based on White Wolf's renowned pen-and-paper Vampire: The Masquerade RPG series.
