The zombie apocalypse is one of the most favorite themes among game developers. Most titles are first- and third-person shooters (with crafting and open world), but strategies can also be found among them. In them you have to either control hordes of zombies, or take control of a small number of survivors, rebuilding their base.
In zombie strategies, you need to monitor the amount of resources that will be constantly in short supply during the apocalypse: food to support life, boards and bricks for construction, medicines to treat diseases, weapons and other important parts that are needed for survival.
Almost all zombie strategies are mobile exclusives, often requiring an Internet connection and the ability to attack the bases of other players.
