Bulltrue

Bulltrue is a medal in Halo 3, Halo: Reach, Halo 4, Halo 5: Guardians, and Halo Infinite multiplayer that is awarded when a player kills another player who is in the act of an Energy Sword lunge. The lunge does not necessarily have to be directed at the player who receives the medal; the swordsman can be in the act of lunging at any player.

In Halo 3, it is represented by a brown diamond with a silver outline and a bull's overlayed on top. The bull's head is white, featuring yellow horns and a yellow nose ring.

In Halo: Reach, it is represented by a dark brown (nearly black) diamond with a silver outline and a bull's head overlayed on top. The bull's head is white, featuring golden horns and a gold nose ring.

In Halo 4, it is represented by a dark blue circle with a light blue outline on top a gray cross that was rotated to 140 degrees to the right, and a bull's head overlayed on top. The bull's head is white, featuring white horns and a white nose ring.

In Halo 5: Guardians, it is represented by a brown octagon with a transparent outline. The bull's head is white, featuring white horns and a white nose ring.

The medal is accompanied with the message, "Bulltrue!".

Tips

A Bulltrue is most easily achieved with dual Maulers, a shotgun, or a Scattershot. If lucky, an assault rifle, dual-wielded SMG, or magnums would work, if the enemy dies right as the lunge occurs.

It is actually a very challenging medal to attain, unless playing Grifball or against inexperienced players. This medal is slightly easier to obtain as a Juggernaut, as increased shielding and damage resistance lead to a non-one-hit-kill with the sword. A popular yet difficult way to obtain this medal is to hit the sword user with a sniper headshot at close range.

Another way to receive this medal is to play Infection or Flood.

Trivia

In the Halo 3 Beta the medal was simply a red star because the Energy Sword wasn't supposed to be found in the Beta's Custom Games and variants.
