★★★★★Sep 10, 2026

why no update like Apple 2 days ago.. Been playing 3 years took 2 get a HQ40. Here's the issues you don't update the events too what players need. Like say it needs too be adjusted too HQ levels I get things totally useless now to me, that be great to swap to other accounts if I bought it. The envelope ridiculously high to send 1 limited item. On threat events put stamina in recharge youll find more will buy then..

★★★★★Sep 8, 2026

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.

★★★★★Jun 30, 2026

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.

too exspensive to keep up and compete

Store description

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!
