No slide, bunny hop, air strafe, just double jump and dash which are both moves that are 100% in "Apex Legends battle royale 2018" and not in many other games like "Doom 2016" Second "Extinction 2020" or even Apex's predecessor "Titanfall 2014". Your title is dead wrong. You could have slid or even bunny hopped once in the video and I would've left 2 minutes ago.
Nah it was a slap to show dominance and how ruthless he is. Bro doesn't care that he won the match. His goal is to rub it in your face as much as possible
With Air dash (L14 Refllex perk 3/3) and double jump (reinforced tendons leg cyberware).... you do this.... While running, perform the following or assign it to a key macro : dash - jump - dash - second jump - dash... It can carry you a good 50 meters. Any other perk is just icing on the cake. The first dash needs to be timed so as not to become a slide, but before you slow back down to walking pace. The second dash needs to be just before the double jump. The third dash should be when you're at the apogee of your jump.
its pretty easy to do this if you put it in mouse 4 or 5 you can also combine it with mid air dash altough it might not be as effective and you can KINDA bhop during johhny memories
