i was on there last week....farted....and the crane collapsed under me.We finally did it with @Osman883 yesterday :
I shoot the counterweight with a single bullet like in the video from @RIZLOID, while the storm was coming and it worked. Well, I don't know if it was due to the bullet or just luck so we'll need more tests to be sure. But there was a player with us and he told us that this Levolution is "glitched". What does it mean ? This Levolution is completley broken for me lol.
I'll work on an important BF4 wiki update when I'll have time (patchnote in page 1). So if you have other ideas, don't hesitate.
