Sigil Games has announced a deal to co-publish their upcoming MMORPG Vangaurd: Saga of Heroes with Sony Online Entertainment, in a move away from their previous partnership with Microsoft.

"As the development process is ongoing and constantly shifting, it became clear that MGS and Sigil had varying visions and direction for the title's development," said Brad McQuaid, CEO of Sigil Games Online. "In the best interest of Vanguard, it was decided that we would buy back the publishing rights from Microsoft."

As co-publisher of Vanguard: Saga of Heroes, Sigil assumes greater control of marketing and PR, while maintaining responsibility for game development, community relations, media relations, customer support, and quality assurance. Under the terms of the agreement, SOE will provide distribution, marketing, hosting and back-end support -- including billing and technical support -- for the game. Additionally, SOE is tentatively planning on adding Vanguard, upon its release,to SOE's Station Access™ subscription plan. Station Access allows players to enjoy all of SOE's MMO titles for one low monthly price.

"We are very excited to be working with so many old friends at Sigil," said John Smedley, president, Sony Online Entertainment. "Vanguard looks beautiful and has an incredibly rich game world. It's the type of game that will appeal directly to SOE's hundreds of thousands of players and should fit in perfectly with the current line-up of games available in Station Access."

"This decision was made mutually by Sigil and Microsoft, in the best interest of the long-term goals for the title," said Phil Spencer, General Manager at Microsoft Game Studios. "As a key Windows development partner, we will continue to work with Sigil to ensure Vanguard's ongoing success."

All three companies will be featuring Vanguard at this year's E3. For more information, head over to the official Vanguard website at http://www.vanguardsoh.com/.
