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 to oppose them... Except for those with the ""hearts of heroes"" who are willing to give their lifes to stop the zombie 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.

I saw an ad with naval ships fighting in an arctic sea and thought it looked awesome ... I don't see that anywhere in the game at all. No sea, no arctic, no ships, ... like ... at all. I saw lines of soldiers firing on each other in an ad for Guns and Glory ... and found instead a game that was identical to this one with simply a different theme (but identical game) ... and no lines of soldiers firing on each other. Wth? I can also see that this is going to advance quickly into a pay-to-win game. It's fun, sure, but I can see it's going to hit a "pay or uninstall" wall soon after level 5.

Hello Soldier, Kindly note that we constantly strive to meet our players expectatons, some of which address the game theme. Regarding the gameplay, we must highlight the fact that RTS games are quite similar as play and upgrade mechanism. Thank you for your understanding, Z-Day team.

This game is like any other greedy mmo strategy game. The resources required to level up buildings and the time for them to be completed grows exponentially larger as you play. Everything in the store is overpriced and then sold "on sale" for over 1000% off. Not to mention, this game claims to be a zombie game, but there are very few if any evidence of zombies during the gameplay, unless the game is referring to the sparse amount of mutants encountered in the game various uninteresting modes.

Have you played any "War Strategy" apps? If the answer is "yes" then you played this one. This game adds nothing new to the genre and has all the gimicks and problems to boot (they're probably going to give a xeroxed response to this review like all others). You've got the standard, it starts out easily enough thing only for it to become increasingly harder with longer waits until a bully high-level player shows up and won't stop attacking. Just pick ONE of this kind of game and play it.
