If you know of any cool tricks to try on maps, post them here! Edit
I only have one:
On Rust,climb the ladder to the very top and place C4 about a foot away from the ledge facing a bit left of the radio tower. Stand on the edge in front of the C4 and detonate it. It will blast you all the way down and usually impale you on any objects below. (usually the radio tower's side grates).
