I just played the demo. All I can say is holy sh*t. I need to hurry up and beat Dead Space 1. The action is definitely more intense, but the game keeps the same edge of your seat horror.
Dead Space 1 made me feel safe in the elevators, nothing ever attacked you in the elevators(especially since they're so small), was in the church part riding an elevator, and one of the necromorphs dropped in. I was like
, and then shot his limbs off with the Pulse Rifle.
