Huhu. I watched demo. I only watched ARMINIUS (ambush) demo, but i watched it few times: normal, shownormals and slowmotion. This is my conclusion:
You (DeMS) are extremely strange player
OR
you use hack with elements of: aimbot, wallhack, autoshot and idiotbot.
#1: at 7:53 and further, there is wallhack element. Normal player would never follow enemy player, which he never saw, over half map same way you followed
straighton. And you knew exactly which way he went - strange, isn't it? I wouldn't notice that he was there, especially because you killed another person there.
#2: at 4:54 you kill guy by giving him 2 helmet shots, which is 100% of your bullets fired. Strange thing is, you pass twice over his head, and you fire only at time your crosshair is on his head. That would be autoshot element.
#3: at 4:42, you're killing guy from far distance, at two times i can notice extremely small movement at his torso, with different sensitivity than you use. They can be only noticed at slowmotion. That would be aimbot element.
#4: all the time, idiotbot is working. Every time you kill enemy,
2 bullets are fired after he's dead. Coincidence?
At 0:30 there is strange situation as well. Which fov you have? I saw the man on left (after you come outside), but you ignored him. Then with strange turn you went to another guy, while first one was still shooting at you.
Still i'm not 100% sure. I'd like another admin to watch this. But to me you are more dirty than clean.
And btw: reloading, breathing and changing weapons makes no sound in Urban Terror
Only you can hear your's sound, nobody else can hear it.
