Eiichiro Sasaki, Resident Evil 6′s Game Director says you’ll get “around 30 hours” of gameplay out of the single player campaign.
Speaking to NowGamer at Capcom’s Captivate event, Sasaki revealed that although the story is a little bit shorter than that of Resident Evil 5, you’ll be playing through with three seperate characters, therefore by combining them together you’re getting something that is much longer.
“While each character’s story stands alone, all of the characters wind up in the same area of the game, in China, so there is a certain level of overlap. They stand on their own but they do overlap in certain areas. You don’t have to play them all, of course.”
