Can explain the scenario and why it is happening, don't be a fool to report me for not being involved.
They're ghost shots, it's a kind of advantage for high pingers, you just hold left click and jump, keeping the aim at your opponent, you won't able to see the bullet trace in your screen but your opponent will eventually receive the damage,
Secondly, he's lagging hard here, his shots getting synced way faster than yours, because of your low ping, it's one of VC:MP 0.4 unfair game play balance, people with fast net or low ping will get to face the ghost shots and delay in delivering damage to their opponents, it's not any hack but a perfect example of why there's a need of an active dev for VC:MP
I hope it clears all, I don't know Blister, I've explained it here because reports like this provokes other to suspect people for nothing, and then consequences for no reason, thanks.
