The game story and mechanics are great. Better than the other zombie survival games I had played before. But sadly its not working out for me. Game always forced me to log out after a couple minutes of playing. Its lagged and terribly annoying especially if you are fighting a boss. I have good connection on my end. I dont know how many times I have to calm myself before I threw my phone out of frustration due to this issue. I just decided to just uninstall it. Its not worth the stress.
