Isaac Clarke's return to consoles may have co-op missions waiting for players when Dead Space 3 comes out next year. But EA still wants us to think that the third entry in their sci-fi horror franchise is going to be a frightening experience. Hence, these screens. I don't know if shivers are running down your spines but the prospect of more out-of-ship sequences would a welcome addition.
For all the people that say its getting so action-y and not that scary. Heres my 2 cents.
Natural Progression, character evolution. You do something enough, one day its not going to be hard for you.
Dead Space 1: Isaac is just an ordinary engineer put in a horrifying situation. He's not prepared for the necromorphs and it shows. Scary game.
Dead Space 2: Isaac, while "crazy", still knows enough about necros that only a few surprises await him, such as the HUGE boss that chases him out an airlock. Kinda scary, lil more action game.
Dead Space 3: Isaac is one of, if not THE EXPERT, on how to kill a necromorph. He has better armor, diverse weapons and can probably curb stomp through a planet. He decides he's lonely so he's going to bring a friend along. Minimum scary, More action-y game.
Though single player on DS3 might actually go back to feeling like DS2 half and half.
Its just how any major character evolves over time. Just look at Leon S. Kennedy, or Ellen Ripley. First time you see/play them, scary as hell, second time, they know what they're doing but still not amazing at it. Third time its second nature.
