So i was playing Left4Dead

…and im in the elevator on no mercy.. I started to remember when i was working on Turning Point and we were having problems with objects with physics on elevators… they would freak out and do some random wackyness.. I started thinking if Valve had a work around for this.. So i grabbed an oxygen tank and took it with me to this elevator and had a team mate stand on the blood stain and dropped the oxygen tank on the bloodstain.. sure enough they teammate fell through the elevator and to his death.. I tested it again with another team mate to make sure it wasnt a fluke and he fell to his death as well lol…

 

(i usually try to carry an oxygen tank in the elevator incase some douche tries to block the doorway with a generator.)
