This game is great, and a lot of fun with friends.
However, the controls are a little rough at first, until you get used to them. They also need more added to it. After surviving and building up a base, the game gets too easy. After like day 50 and day 100, they should increase the difficulty and add much more zombies in the red moon.
Also, there is no reason the server should only hold 4 players. Specifically if they add a trophy to kill 2,000 other players. When only 4 people can join the game? That is ridicules.
The game could use a few updates and add more content to the game. But for what it is, it's still a lot of fun for a survival game.
