No, not if it lands "close enough". If it lands in your hitbox and gets stuck. my friend does it all the time, he throws his grenade at me and it gets stuck on my body. If a non-attachable grenade lands on an enemy player it does some amount of damage on impact. And when thrown at the correct area on a players body, it stays there and does a lot of that damage very quickly. thats what I meant. I exclusively play striker and have never once been one-shot or have one-shotted anyone just because they were closer to the grenade itself. it always takes 2 pulses to kill (with the exception of modes with level advantages enabled).
