Atom Zombie Smasher is a real-time strategy (RTS) game developed by Blendo Games. The main goal of the player is to save the citizens of a city from a group of zombies and meet the set score before the zombies take over. The players will have to use several helicopter rescue units and offensive military units in rescuing the citizens and controlling the zombie horde. The game makes use of procedural generation, a gameplay mechanic which ensures that each instance of play is unique.
The game Atom Zombie Smasher starts with the city Nuevos Aires being attacked by a crowd of zombies. In every mission, players are required to rescue citizens of the city using the helicopter units and simultaneously assign military units at different locations on the playing field. Citizens touched by the zombies will become zombies, and more zombies will start to appear during night time.
Winning a game, especially before night time, will allow the players to control and clear out an area of any zombies. Every mission completed by the player will also give the player a bonus and allow the unlocking of other military units that can be used for the next mission. However, when the player fails at a mission, the zombies can take control of the area.
