Of course, Valve patched it and that's what made him quit, so that's why you can't bhop like that in CS Source anymore and neither in GO. He was able to hop to insanely high velocity rates using a bhopping exploit that he used.
The demos are recorded in a low tickrate (If I remember correctly: 32 ticks) so it makes it harder to know what kills are legit and if the hops are also legit.Īnd another big factor was the Source engine bhopping exploit he used in ESEA and Warlord servers.
Yes, he did this without any external/internal cheats or scripts.
