2K Games today announced that it has acquired publishing rights to Gas Powered Games' Dungeon Siege series. The first new titles under this publishing agreement will be Dungeon Siege II: Broken World, an expansion pack for the best-selling PC game Dungeon Siege II and an all-new entry in the Dungeon Siege series, Dungeon Siege: Throne of Agony for the PSP™ (PlayStation®Portable) system. Dungeon Siege II: Broken World will be available this summer and Dungeon Siege: Throne of Agony for the PSP system will be available this autumn.

"The Dungeon Siege series has always been known for its beautiful graphics and great single and multiplayer gameplay," said Christoph Hartmann, Managing Director at 2K Games.

"2K Games is fully committed to expanding the franchise on PC and new platforms like the PSP system."

Dungeon Siege II: Broken World picks up right where Dungeon Siege II left off with an all-new campaign mode, a new playable race, more items to discover and a brand new multi-class character development system. Dungeon Siege II: Broken World will require the full version of Dungeon Siege II.

"We're excited to be working with 2K Games," said Chris Taylor, Founder and Creative Director of Gas Powered Games. "We're expanding the Dungeon Siege universe on the PC with a new campaign and opening up even more new territory on the PSP system with a second, unique adventure that you can stuff in your backpack and take with you wherever you go."

Dungeon Siege: Throne of Agony for the PSP system, in development at SuperVillain Studios, is another entirely new adventure created from the ground up specifically for the handheld system. Dungeon Siege: Throne of Agony features all-new playable characters and a freshly designed, non-linear, single-player campaign as well as support for Ad Hoc co-operative and competitive multiplayer games.

"SuperVillain Studios is very excited to team up with Gas Powered Games and 2K Games on the development of Dungeon Siege: Throne of Agony for the PSP system," said Tim Campbell, co-founder and project lead at SuperVillain Studios. "This title represents an important step for the Dungeon Siege franchise by extending it for the first time ever onto a new platform, merging together the incredibly rich legacy of the Dungeon Siege universe with a fresh, handheld-oriented gameplay experience."
