I don't know if this is a known glitch or not but I thought I would share it here just incase anyone finds out how to replicate it or make use of it. I had cortical scaledown, angular advantage tactical munitions, composite helmet, and speed enhancer total organ package with the full damage ZKZ.
Shots 1-5: Clearly missed. Shots 6-9: Missed due to recoil (bad spray control). Shots 10-11: Very close, but recoil and inaccuracy make these reasonable misses. Shot 12: Likely didn't actually fire because you were already dead.
Do you have any idea what your inputs were when you did it? I'd love to re-create it and mess around with it a bit.
My current theory is that I took damage from a ricocheted bullet from my gun while I was pressed up against the wall holding W and as I jumped the damage caused me to get launched forward.
