i don't believe there is a good way, though i honestly can't say for sure
Well that sucks because that's the whole point of it the add-on is basically when you hit or shoot someone a little
X appears in the center of the screen so you know if you hit them or missed
Example: a TDM and i randomly throw a grenade in the air and i didn't kill anyone ,but i want to know if i at least hit someone so i can go in that direction where i threw the grenade and kill them
