A lot. As far as I understand it, if you land on an edge in Counter Strike at just the right angle, it'll reset your speed while cancelling fall damage. Since CS2 and Deadlock are in the same game engine, whoever made this video ported the map files to Deadlock where they're just bullshitting around and performing edge bugs... where it's useless, as Deadlock doesn't have fall damage. This entire thing is just one elaborate shitpost.
