He doesn't script but some of the shots look very messed up. I think its the FPS that he was recording on. I personally would use 500 instead of 120 or 240 so there isn't motion lag.
Wow great vidd some amazing bhoping going on there. And bhop on zblock is a match toggle so if both teams want bhopping they can have it. I doubt he was scripting hes doing all the correct mouse movements for it and even if it is a script thats still some pro jumps.
well there is a way on going fast even i know how..... i can bhop if the server has a good enough airaccelerate... people even say i script when i bhop in like Deathrun and stuff i go over 1000 velocity. but this is crazy good. but i see how the motion moves back and forth its like all perfect... somthing like yawspeed?
