This is a classic shoot-em-up zombie game that will get progressively more difficult as you move on. The game starts out very simple to make sure that you get the hang of it but it escalates very quickly. If a zombie catches up to you and either scratches or bites you then you’re in trouble! Any fan of the Call of Duty Nazi Zombies games will love having this option while they’re on the go! Get ready for the apocalypse!
