U can use GUI Text go to Game Object → Create Other → GUI Text
and apply this script

var TextTop : GUIText;         // assign GUI Text

function ShowText()

{

  TextTop.text = "3";
yield WaitForSeconds(1);
TextTop.text = "2";
yield WaitForSeconds(1);
TextTop.text = "1";
yield WaitForSeconds(1);
TextTop.text = "Go....";
}
