I would think twice before purchasing this game solely due to the lack of internal security. Although this is not the first game/company to experience hacking (think Sony), the compromising of my user data is troublesome. If you do decide to purchase/play, I highly recommend you choose a password that is unique only to this game to limit further exposure.http://arstechnica.com/security/2013/04/war-z-taken-offline-following-hack-that-exposed-user-passwords/
Don't support this game/company any further as it is riddled with problems and pending lawsuits. Until issues are addressed or an action plan established, steer clear.
Most likely... this post will be deleted or buried per 'strict posting guidelines' of this forum. Nonetheless, I found it necessary to share this information.
