A zombie apocalypse setting in a desert wasteland, where i and a few survivors are erecting a big wall of window blinds in our base. Probably some kind of shielding technology from the potential radiation in what i assumed was a developing storm. However, i hear the bloodcurdling screeches of what only brought me and the others blinding terror. It was like the sounds of inhaling and exhaling, only loud, high pitched, and drawn out. The mutant creatures rushed through the camp, using their great agility to leap and bound menacingly across their environment, Their skinny, starving bodies a pale pink, glide-efficient wing-like appendages stretch out from their bodies to their arms. Their faces had no eyes. They tore through our men, tearing them apart with what can only be a demon's efficiency. Everyone fled into rooms and buildings, knowing full well that the bladed claws of their enemies were specifically crafted for tearing flesh and not the hard materials used in the constructs of man.
