its happening randomly that when i jump from the last step of a stair or go down into the pit of the broken staircases that the screen tells me you are dead. this is a bit unrealistic within a survival game :)
additionally when standing on a balcony and activating a weapon i felt thru the house to death.
and on the electricity facility near elektro i felt thru the roof with no extra moving. i was just walking on the roof... dead
