My friend and I were at our stash, completely hidden away and made sure we weren't followed by waiting a few minutes before going to the stash.
We were just about to log off when we heard someone drop behind us, and extremely fast foot steps. We both backed away and regrouped, once established I broke away a little from my friends perspective. As you can see in the video they were obviously hacking. Once my friend went down, I had swapped to game chat calling them out for their childish actions. When the one of the pair fully stopped, I shot him but that produced no animation. Once he was shot his friend instant turned around and killed me.
Luckily got a close spawn and I tried running back to our stash, to only be teleported on. I proceeded to punch them but they instant killed me.
