I played with my friend. We were in Berezino factory area. My friend was in a closed little windowless yard and i laied in the grass 30m far from him next to a contener in a corner. In a moment we died in the same nano sec independently, without any noise and it couldn't be a grenade, because we were separated with 2 beton walls far away. How can it be happen? Maybe it was a cheater?
