The brave few who have the stones to take on Dead Space 2's Hard Core mode are in for a mentally debilitating experience. With so many instant deaths lurking around each corner - each poised to set you back five to ten hours - you are understandably going to become more than a little paranoid. You'll begin crawling at a snail's pace in anticipation of Exploders, Cysts, and worst of all, the dreaded Eye Needle and Ubermorph room. Cornered by a group of undead kids? Dead. Hit by a broken door? Gibbed. Accidentally shoot out the glass window on a space station? You died, kiddo. Keep that in mind the next time you see an air vent or hear a strange noise.
