Resistance is futile! If 0 ohm
Go back to COD.I for one favor some genre bending and the occasional fire fight; it'll make a nice contrast to the 'peekaboo fuck you' engagement style of the necromorphs in the past 2 games.
That's the whole point of Dead Space. Trying to survive a actual threat instead of a bunch of dudes with a survival instinct of a lemming with guns.
