The trailer’s official description reads:
While patrolling the planet Uxor, Earthgov Sergeant John Carver witnesses an attack on the Marker Site he guards which changes his life forever. John must now fight his way through a colony now in complete chaos as he begins to discover how important he is in fighting the Necromorph plague.
John Carver or not, there’s still Necromorphs and whatnot so it’s still Dead Space. Now, while this might obviously be for Dead Space 3, does this mean we’ll be getting a new protagonist? Rumors have been circulating since early this year that Dead Space 3 will feature co-op. Perhaps John Carver will team up with Isaac Clarke in the third game in the series?
We’ll know the answer to all these once E3 rolls around starting early next week.
