Twice in one day i've been killed by a group of zombies that i can hear them raging but cant see them cause the game lags... you can run but you will die cause no matter how fast you are they keep on hitting you till you bleed out or gets knocked out and its game over... it happed to me in the big airfield in chernarus and later the same day in Livonia... i think the location was called tarkov or something... love this game but hope they fix those small things that add up and make it hard to play
