Survive the Nights

Survive the Nights is another first-person shooter survival game where your main goal is to stay alive amidst zombie infestation. The game has a day and night cycle. Zombies' behavior depends on it. The day is the best time to collect supplies, find a shelter to reinforce it with solid materials, and place various traps nearby. The daytime is also great for hunting down prey for a meal. Zombies aren't that active under the sun. After dusk, you'll be on your toes fighting off attacks from hordes of living dead. So, you'd better refill your ammo and fortify your shelter beforehand. Needless to say, it is co-op FPS and in-game goals are easier to achieve together with your brothers-in-arms i.e. other players.
