If you don’t wanna watch the video ( you probably still should), read this: basically the survivors could press a button that takes two seconds to knock down a wooden plank, the survivors could then jump over this wooden plank to gain an advantage over the killer, but the killer cannot jump over this plank, the only way for the killer to get through is if the killer destroys it. This could be used during loop-able gaps between walls or windows
