@Paul Benn Even tho the answer is way late, you are wrong. There is a console command for wallhack. The command is r_drawothermodels 2 :P doesnt work on servers with sv_cheats 0 obviously
in therms of success i would say f0rest since he won tons in 1.6 and csgo, Neo is definetly a candidate too. soley on csgo i think nobody has been as good as olof was.
you're fucking stupid. It was a professional team (actually still they are, but CS:GO) and this is just a moviemaking effect by a console command by the moviemaking program. newbie
You'd be surprised what I do and don't know about css... Probably not more than you but still enough to know that there is no console command which activates a wallhack...
