Eric Bossick who, provided both the voice and motion capture for Silent Hill 4‘s protagonist Henry Townshend, claimed that he’s working on a new game with Hideo Kojima. He did not make it clear if it is the rumored Metal Gear Solid 5, but did note it is unlikely to release before Summer 2013.
“I am working on a future Metal Gear, not to be released until next year summer at the earliest, if not later then that,” said Bossick in an interview. “I’m doing motion capture only. I can 100 percent say my voice will not be involved in this. I don’t even know what the title is, they are all very secretive and sometimes even the scenes I act out I don’t even know the full story, because they want to keep it secret.”
“I suppose it is fine to mention I am working on it, everybody knows Kojima is making something now, and I posted the photo on my page here with him,” Bossick added. “The only thing is that I can’t ever answer any questions about it or talk about, not for sometime.”
