we already figured out how the race happens and the transparent effects. and the menu can used by the server identifying player position packets. it can only be used in safe zones. this is very complicated but: the player sends a gun fire packet server identifies location of player player moves up or down, (and up is up, down is down, left is up, right is down) sends gunfire packet server identifies which direction the player went moves menu arrow in said direction one menu item up. firing bomb can select a menu item, a mine goes back a menu item but this method wasnt used for this. the video was made using a patched client (outside program). i assume the menu was done with that program.
