One time, a hero did that to me, but I caught him in the middle of placing mines on the outside of the box. I just waited for him to pop up to place one and shot it. Got both a Hero Kill and my I.E.D accolade maxed out .
Anyone can do it,Even the black box carier in black box,I never did it before cause I think its really bad cheating but when I saw someone else do it I was so annoyed:wtf::mad5:
I dont think that black box carriers can do that since they cant vault over the first box. But when an enemy hero is hiding in the box I go in after them.
