Heavy Rain will be fully voice acted in 10 languages, with subtitles available for all spoken languages, plus six more languages. These details were disclosed during a presentation at GamesCom this afternoon, when Quantic Dream founder David Cage introduced Pascal Langdale (pictured right), the actor playing the English-speaking version of Heavy Rain's Ethan Mars, and discussed the extensive voice work necessary for the game's many branching scenes.
Knowing a single Blu-ray disc can store language data in bulk, we were curious about how many language options would be available in the game. As it turns out, if Cage had brought in all of Mars' voices, the room would have gotten pretty tight. Check out the confirmed list of languages after the break. (We're still waiting for official confirmation on a couple -- the Quantic Dream team couldn't name them all off the top of their heads.)
Update: Heavy Rain's associate producer and localization manager, Romain Castillos, has given us the official list of languages and subtitles.
