One of the most anticipated role-playing games this year is Activision and Troika's Vampire: The Masquerade - Bloodlines. Set in White Wolf's rich role-playing universe and using Valve's cutting-edge Source engine (the same used to power Half-Life 2), Bloodlines will let you live the life of a vampire in a dark and seedy version of the Los Angeles underworld. The developers at Troika have a history of developing role-playing games, including the famed Fallout games, but this is their first attempt to create a role-playing game with first-person action. Leonard Boyarsky, the game's project leader, recently visited the GameSpot offices to show us some of the gameplay in Bloodlines.
