In this world, noise kills. Breaking glass, slammed doors, gunshots—and even a hungry infant’s cry—draw the dead from every direction. Plan every move: scavenge formula and meds, craft weapons, slip in and out of houses quietly, and if things go south, sprint for the car and make a break for it—risking a horde with the roar of the engine.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3937480/extras/d6925dc814475f1497f8fd0310da1d66.poster.avif?t=1769983896" width=616 height=128 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3937480/extras/d6925dc814475f1497f8fd0310da1d66.webm?t=1769983896" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3937480/extras/d6925dc814475f1497f8fd0310da1d66.mp4?t=1769983896" type="video/mp4"></video>Cities are procedurally generated: new districts, interior layouts, loot spots, and escape routes force you to rethink your strategy every run.
