here you go someone finally helped me
Happy? there's 2 ways to get in there BTW NO ONE CAN SEE YOU AT ALL 1# is the easier way but it can't be done if someone breaks the barrel. Okay to get in you have to go the edge of the crate just like the gray hammer glitch and do the same thing.2# The other way is to knife the side facing the ridge then crouch and move side to side until you find a bump that pushes you back and then you move to the right as the bump still pushes you
EDIT:Sorry ignore all except last one
