3-4 years ago . I just started playing pubg mobile.I was very nub at that time.me and my friends always do camping to avoid fights.I can't remember the place it was ,but there was a 2 story house we were camping at the second last circle. But our luck was not with us . Zone shrinks and we had to move out to a open field.only 5 people left including 3 of us. As soon as we entered lurking in the ground, my two mates got killed. We thought we will lost this match like previous ones. I was a little far from my friends location,and I throw a smoke bomb towards my friends body. I couldn't see the enemies because they were also snaked.I had a Ak47 without any muzzle and suppressor. I fired randomly in the field and by luck I shot the enemies.O couldn't believe I win the match with 2 kills without even seeing the enemies.
