Bulltrue

Bulltrue is a Halo 3 Multiplayer medal that is awarded when a player kills another player who is in the act of an Energy Sword lunge. The lunge does not have to be directed at you, as you can get a Bulltrue when someone is lunging at another player. It is represented by a brown diamond with a silver outline and a bull's head in the centre. In the Halo 3 Beta, it was simply a red star, because the Energy Sword wasn't supposed to be found in the Beta's Custom Games and variants. It is easily achieved with dual Maulers or a Shotgun. If you are lucky, an Assault Rifle would even work, if the enemy dies right as the lunge occurs. It is actually a very challenging medal to attain, unless you are playing Grifball and your opponent is not very experienced.
