Something’s stirring in the vent. Panicked, I force Isaac Clarke – protagonist of critically-acclaimed horror game Dead Space – to spin around in circles to locate the source of the terrifying sound. Behind me, a grotesque creature bursts forth from the wall and slashes at Isaac’s back. Disoriented and frightened, I lose all semblance of control and fire my plasma cutter wildly in the hope of hurting my foe. Dead Space’s iconic necromorphs had a knack for placing players permanently on edge.
