We've heard Isaac Clarke's voice, and it's deeper than you'd expect. It's also got an edge of fear that simply didn't manifest as he stomped through the Ishimura, saving the day with nary a whisper or whimper. If you're worried that a talkative Isaac Clarke might ruin Dead Space 2, though, you shouldn't be. "In terms of how much he talks, last game, zero," said executive producer Steve Papoutsis. "This game, he's somewhere between a two and a half and a three. He's not really wordy, he's not shooting off a bunch of one-liners, he's just speaking when it makes sense for the story."

Isaac's goal in the train station is to reset a train car, and once he clears a few necromorphs away, he must hack into an electronic box, which requires moving the left stick around until it vibrates into the right position. Despite the fact that Isaac now talks and reacts, Papoutsis confirmed that the hero is still a futuristic IT guy with a better uniform than the Geek Squad. "Isaac is definitely still an engineer," he says, "so you're going to encounter a lot of puzzles throughout the game where he does have to use his engineering know-how to get by a situation." After clearing the hackbox, the train starts rushing down a tunnel, and that's where the gameplay picks up.
