Can be used a flashbang to kill a person
Put it in somebody's mouth and I'm sure nothing good will come of it.
No...it just disables the vision of the person.It would not kill him.
Yes you can if they are down in second chance or if it hits them enough. I had my god sister in a corner and threw one at her and it kept bouncing off her head until she died.
depends u talking in a game or in real life?
