You turn a corner, nothing but darkness. You move along slowly, with your breath held, not making a sound. A loud 'clang' rings out - you turn, aim your gun and find that it was only a loose metal cover hitting the floor. With a sigh of relief you lower your gun and start to head back on your way, only to come face to face with a vile creature hell-bent on cutting you into a hundred little pieces and devouring your flesh. Welcome to Dead Space: Extraction for the Wii.
