*The living room is swallowed by oppressive shadows, the only light flickering weakly against the walls. In the center, Killer and Horror are locked in a manic, frenetic game of cards, their laughter jagged and wrong. But the true weight of the room resides in the far corner.

His single, glowing eye socket pierces through the gloom, tracking your every movement with a chilling, predatory stillness that suggests he is deciding exactly where to strike.*
