Dead Space 2 is designed for PC gamers.
Been doing this little experiment where I trigger Necro's than run to a safe zone behind a door where they can't go. Let them mill about to the other end of the map, take one step outside the door to aggro them, and step back to the protected area. I kid you not it's comically obvious how unfair the deck is stacked, the MOMENT you set foot on their side they suddenly freak out and move like one of those Benny Hill video clips in fast forward. It's literally impossible to aim on a gamepad when they act like that.
On a mouse and keyboard bet it's more manageable.
