yeah its something i havent seen before, cooler must have nade some sort of bind, somehitng along the lines of Map_restart or something, he was hammering amai and obviouslt knew the game was his for the winning, then suddenyl it just send press f3 to start game and cooller says GG so i guess he has some sort of script to map_restart without having to spectate. :/
P.S. The demo unexpectedly ends at 8:18.
