I had been on Livonia in Lukow at the Police station with a friend- I am holding a shovel and two enemies with NVG'S outside begin to open fire. I take four steps behind the sandbag wall and hit RB - open the hotbar and BOOM I am frozen and cannot move. I am shot twice , my friend distracts. The zombies begin to swarm. I try holding X to drop the shovel, pressing start to open the menu, nothing. Simply frozen. I couldnt even log out if I had tried.
