Joe Flanigan, who you may or may not know from TV shows such as Dawson's Creek, Stargate: Atlantis and Fringe, seems to have inadvertently confirmed EA's working on Army of Four.
Over the weekend the actor said on Twitter that he has signed up to do voice acting for Ao4, which has yet to be officially announced by EA.
Just signed on to do the new AO4 video game for Electronic Arts. Some splinter from Battlefield.Finally, my kids think I am cool again— Joe Flanigan (@JoeFlanigan) March 3, 2012
At end of last year, an anonymous source claimed the game will feature four-player co-op.
It's reportedly being developed at EA Montreal, the studio that worked on Army of Two: The 40th Day, and will be powered by Frostbite 2, the game engine used for Battlefield 3.
