First thing first- This game is a PC port of a mobile game so it has microtransaction and gameplay design that demands heavy grinding to progress further.

This game is one of those game that could never achieve its full potential because it is constraint by a certain monetization strategy. Now This game isn't all bad, the gameplay is based around call of duty Zombies but with tweaks that makes it less fun. The survival mode is good and fun to play, the rogue like mode is great but has been limited by the Token system where you cannot play it unless you own tickets to enter.

There are few annoying but bearable part of this game but The weapons system in this game makes absolutely no sense. Weapons like Shotgun doesn't do jack sh*t even when shot at a point blank range. Shotgun and snipers are worse off than pistol at the same power level. Not to mention The headshots means nothing in this game. The pistol, rifle and Explosive are the only weapons that do any work. It is like they decided to total ignore the established mechanics of weapons like shotgun and Snipers that most FPS games do. Then there is almost a 2 second lag when aiming down the sight after switching guns, That delay is something that shouldn't happen at all. also all the powerful weapons are locked behind outrageous pricing that requires lot of grinding to get in-game currency for free. The enemy also gets tankier in health as you move to higher levels and so you will be forced to get better guns to progress in the game.

The game does have some good aspect to it like The survival mode is good and it alone make this game a bit playable otherwise the stage wise sections are just boring. Rogue lite mode is great but limited by the ticket system. Then there is a shooting range which I love a lot, I have spent a lot of time on it. personally I also like the variety of good maps across 11 regions and the secret location that they hide in each map.

If you are looking for a great zombie shooter experience, then Left for dead and LD2 are million times better than this game but so are many other zombie shooter on steam. This one is at best a 5/5, buy it during sale. It's not a bad game but it's not great either.
