The situation should be analysed more carefully, because in the first video I was playing with the other gta, which had bugs, I even had reported one of them here:
https://mikescnr.com/forum/index.php/topic,11409.msg54525.html#msg54525And when Mike replied to me that the cause of bugs was the game, I looked for the new gta game and installed, which has more performance, advantages and etc.
Futhermore, this "xulera" in the first video was fighting me very intensively so of course it was hard to kill him, but if we watch in the second video his position and his moves, I mean he was an easy target, and this double barrel shotgun does alot of damage from close distance and that gave me the advantage to take away much more hp and faster.
Also I have to apologize, that I haven't got any recordings, I will start recording in the future my gameplay.
