War Z has been going through hell ever since its release. The developers were first accused of falsely advertising their game and even accused of ripping off images from the Walking Dead drama series. Furthermore, the critical and user response the game has received; is downright abysmal.
As if all this was not already enough, the servers of the game have been under constant attacks, mostly DDOS attacks on the login screen. In fact, these attacks have caused the servers to shut down. According to ‘Kewk ‘, community manager at Hammerpoint Studios, the game is up and running since 1:30 PST yesterday. He made this statement on the game’s official forums.
