I apologize if this is common knowledge or has been answered elsewhere but I could not find an answer to my question from a quick google search.

I am watching the FAZE x Sentinels game and saw FAZE's ZachaREEE as Cypher on Bind defense holding A site outside of showers on top of those boxes in the corner next to bench. I know you can jump up to the lower box, but did not think you could jump up onto the highest box (which was where ZachaREEE was holding) without some mobility utility (eg updraft, shadow walk, blast pack jump) which Cypher does not have.

Their team comp was Cypher, Omen, Sova, Jett, Raze so no Sage wall to boost him up either. Perhaps Corey's Raze used blast packs to boost him up there, but I didn't think you could move your own team with Raze blast packs either..? Anyway, how in the hell did ZachaREEE get up there? Is that just some normal jump thing you can do if you're good that I didn't know about because I suck mechanically? Some kind of tricky map geometry bug?

tl;dr how did FAZE's cypher get onto the tallest box in the corner outside of Bind A showers?
