Castlevania: Lords of Shadow - Mirror of Fate, the 3DS title in development by Mercury Steam, will incorporate Nintendo's StreetPass feature, allowing players to swap game data simply by walking past one another. Mercury Steam and Konami confirmed its integration today at E3.
Mercury Steam developed a brand new engine for its 3DS installment and now has 100 people working on Mirror of Fate and its companion console title, Lords of Shadow 2. Both games operate in the same Lords of Shadow universe, at the same time, but Lords of Shadow 2 will conclude Dracula's storyline while Mirror of Fate tells the Belmonts' tale.
Mercury Steam will be finished with the Castlevania franchise after these titles launch.
