Yea it's true that another one was shooting at me, but if you look more clear you can see how he used health hack and took very much health percent with 2 deagle shoots. I would suggest to look the video from second 0:24 to 0:26, the other player that was shooting me with M4 was behind and you can see how the hacker reduced very fastly my health. He was using health hack and aimbot, for this im sure, and it's upto you to decide now
