I can't hold it any longer. I have given this company the benefit of the doubt (along with my money) for a very long time.
The game is literally unplayable. Every other game end with either a connectivity to the server error (I'm on a wired connection with a very reliable ISP - largest and best in the country - or with a DEV error. For example, after a few hours of playing one single survival game... it crashes and all progress is lost.
To top it off, it's been more than two months where I cannot play any Local mode due to the widely reported "Your data is corrupt. Reset all your stats" error. After numerous emails to tech support (without any answers by the way) it is still not fixed.
For such a very expensive game, coupled with the micro payments approach, I guve the company 1 star because of the disregard of the player base and the disrespect of the their paying customers.
This is a best case of a company that became too complacent with their success.
