Unfriggenbelievable (Unfrigginbelievable in Halo: Reach and Demon in Halo Infinite) is a killing spree medal in Halo: Reach, Halo 4, Halo: The Master Chief Collection, Halo 5: Guardians, and Halo Infinite that is awarded for killing 40 enemies in a row without dying in Multiplayer and Spartan Ops, and for killing 1000 enemies in a row without dying on Campaign or Firefight. In The Master Chief Collection it is only awarded in multiplayer (which includes Spartan Ops), and not in campaign, for which the highest killing spree medal is Invincible.

In Halo: Spartan Assault, it is awarded for killing 50 enemies in a row in co-op without being hit, and is represented by a blue shield with a Pod infector over three inverted chevrons.

In Halo 5: Guardians it is represented by a blue skull on top of a purple and black hexagon.
