Dark Soul's Debut Trailer

Dark Souls is the spiritual successor of Demon's Souls, an action adventure role playing game developed by From Software that was released in 2009. Like Demon's Souls, this game will also likely have an unique online multiplayer system integrated into the single-player where players can leave useful messages, help other players directly, or invade their worlds. Like Demon's Souls, Dark Souls will likely continue the dark fantasy theme along with a challenging and tough gameplay experience.
