The zombie apocalypse has broken out, and the only way to stay alive is to play the action game Z Survival Day. The objective of this game is to eliminate all of the zombies that approach you with a weapon that allows you to select from a variety of attack distances. It will be easier for you to complete the stage if you make use of the many power-ups available to you, such as grenades. The number of lives available is displayed, and there is a first-aid kit at your disposal. It has intuitive controls found on the lower right portion of the screen. There is also a map on the upper right to help you navigate the place.
