You might like the witcher 3. Not really zombies but theres cool things to explore and other fantastical stuff.I tell my kids..I wanna play a game where you kill people and find treasure rofl. Bonus if it's zombies or dragons or something relatedly fantastical. They look at me like *I* have 6 heads. They're hard core Call of Duty and War Tanks or something fans. Although there's a new zombie game they've been playing and liking, I just haven't had time to check it out yet.
