I found a way to jump from heaven to the boxes in front of default in A site haven. Is this intended or not. Its possible with any agent. It's probably consistently possible with enough practice. https://www.youtube.com/watch?v=60AXSPVedfw
The VAL devs mentioned that they wanted to incorporate skill jumps in the maps, so it's most likely intended. Nice find though, will definitely need to practice this. Now I can actually get down from that window without losing half my hp.
