"We are looking forward to turning the vision of our game designers into a compelling online gaming experience. The planning and design completed for Project: V13 thus far, combined with Masthead’s resources, tools, and growing team of dedicated MMOG developers, will bring this unique game to reality," said Herve Caen, Interplay Chairman and Chief Executive Officer

As a part of the agreement, the game will utilize Masthead’s proprietary tools and MMOG technology developed for Masthead’s "Earthrise" project.

The game has been in design and development at Interplay since November 2007. Masthead and Interplay teams will work together under the direction and control of Interplay to complete development of the project.
