World War Z Aftermath

Across New York, Moscow, Jerusalem, Tokyo, Marseille, and now Rome, Vatican City and the Russian far east, the undead apocalypse continues to spread. In-game Zombie Hordes behave like real crowds, getting stuck in narrow corridors and climbing on top of each other to reach players on higher levels. Hordes become increasingly more difficult to defeat and behave like single entity bosses as players progress through the game.
