Seriously?
Ok so picture a vehicle crash derby, the maps are just large vehicle pits to drive around in (but you can't use the vehicles). Absolutely the worst possible environment for zombies because there is no where for them to enter the map.. So they just spawn smack-dab right in the middle of the circular map, right in clear sight. The zombies do not reduce in numbers so killing them is pointless, they spawn faster than you can possibly kill them off so there is absolutely zero point in killing them. And forget trying to enjoy killing off zombies with a gun because all guns only have one clip making the only viable option of defending yourself a melee item. There is infinite zombies and at no point do they ever let up because the moment you kill the 10 attacking you another 30 respawn 50ft away from you. Even if you do find a gun each zombie takes 2-3 headshots even on easy mode. Its really just not enjoyable at all.
The objective is to pick up 5-10 items in different corners of the circular map, doing this then magically enables you to enter a helicopter and fly off to safety. Once you die you can not respawn so every single player that dies just instantly quits the server. Its really your only option because nobody wants to sit around watching some other player hit a neverending supply of zombies with a crowbar for an hour
And there are vehicles scattered across the map but none have fuel in them, even if you did get lucky enough to find fuel you can only drive 50ft before it runs out.. So its like a vehicle game without the vehicles. The only way to really see how bad this game is to try it out.. But i would not reccomend spending even one penny on this game. The only good thing about this game are the graphics but thats all thanks to the unreal engine
