Two modes: Open-world campaign and wave-based zombie shooter. Patrol through an abundant apocalyptical New York and fight against hordes of zombies, religious people calling out the "judgment day", and bandits who are terrorizing unarmed survivors. Survive in various co-op story campaign missions, events or open-world encounters with up to 3 friends or bots. Go on supply missions together and collect food and water for citizens who are starving at survivor camps. Collect resources to upgrade your survivor camp. Keep the bandits away from the streets. Gather information about the "judgment day" religion and cut off their supply lines. Craft and upgrade your weapons. Find out what happened to missing citizens or agents. About the demo:The demo (which only shows how the horde-mode is going to look) is limited by weapons you can buy, perks you can achieve, upgrades you can activate, objects you can craft, maps you can conquer, and types of zombies you can fight.
