About this game

The history you know is not necessarily true.
In 1944, the Allied Forces landed in Normandy, which is now referred to as D-DAY.
Evil scientists used weapons that could change the weather, which led to the D-Day battles in Normandy failing in the storm.

In 1945, the Nazis set off an experimental Antimatter Bomb, destroyed most countries in the world, and destroyed social rule.
This day is called Zero Day, or Z-DAY for short.

In this dark new world, evil forces seek to conquer all humanity, and none dare oppose them... Except for those with the "hearts of heroes" who are willing to give their lifes to stop the apocalypse!

The evil captain is already searching for the Antimatter, a compound with an infinite power of destruction. If nobody stops him, he will erase the entire human race and turn every human being into an undead zombie.

Played this for >9months. The devs come up with ever more ways to incite you to spend more. (but you don't have to, of course :-)) My conclusion: With reasonable spending of time&money it is only possible to go to lvl 26 and maybe a few more. After that too much time&money needed and the fun stops. They count on the addictiveness so you won't quit and I suspect some of the big players are dev accounts that push you to spend more. Big total rip-off, even purchases are a lottery. DO NOT INSTALL.

Hi Soldier, We do realize that a real-time multiplayer can be challenging and we appreciate you took the time to let us know your concerns. Although we encourage you to constantly work on your strategy, you can also ask for some tips from the Support service as they are happy to assist. Thank you for your understanding, Z-Day team.

Game started out good. 7 years later absolutely nothing new has been put into the game and just turned into a money grab pay to play. Dont waste your time or money.

You can play without real money but you will not be competitive in any event. A player would need to spend roughly $12,000 to be decently equipped. There are a lot of whales in this game. If you like redundant pointless clicking this is the game for you. Customer service is more than likely AI, either way pretty worthless. Good Luck.
