It's a very good zombie survival game with awful optimization and performance. Graphics is good, not great but good and I have many lags during the game especially when you face a horde or running between buildings and walls. Core i5 8400 + AMD RX580 + 16GB RAM and still have low frame rate and lags. Optimization and performance is really bad even after 2 years. Also, like every other Microsoft game, the servers are really bad and sometimes you can't play with your friends.
