Command and Conquer DEN has a press release from Vivox announcing the voice communications outfit has signed a new deal with Electronic Arts to provide integrated voice services in upcoming online games (thanks Ant). Command & Conquer 4: Tiberian Twilight will be the first game to feature Vivox when the RTS sequel is released:

"Command & Conquer 4 is a huge leap forward for RTS games," said Rob Seaver, CEO, Vivox. "EA recognizes the impact that voice will bring to Command & Conquer 4, both tactically and socially, and it is a terrific title to kick-off our relationship. With voice, players will experience and create new levels of gameplay for themselves, making the connections they need to move ahead and win the game. It is amazing to work with EA to craft a new experience for the RTS genre, and we expect to keep innovating with future EA titles."

Command & Conquer 4 Tiberian Twilight, the next installment to the bestselling, critically acclaimed real-time strategy franchise, will feature new levels of competitive multiplayer gameplay, including new features such as the 5v5 objective-based multiplayer mode. This functionality will elevate the social real-time-strategy experience, with the focus on teamwork and cooperation, which will be further enhanced with Vivox' voice chat.
