Untouchable
From Halopedia, the Halo wiki
Untouchable (known as Overkill in Halo 2 and Nightmare in Halo Infinite) is a multiplayer and Spartan Ops medal awarded for killing 25 opponents in a row without dying. In campaign and Firefight it is awarded for killing 50 enemies in a row without dying. In Halo: Spartan Assault and Halo: Spartan Strike the medal is awarded for killing 20 enemies in a row without being hit, and is the highest kill spree medal.
In Halo 4 it is represented by a gold and white eight-pointed star with a gold target in the center.
In Halo 5: Guardians it is a gold and yellow eight-pointed star with a white target in the middle. In prior games, the star is white and 16-pointed.
In Halo: Spartan Assault and Halo: Spartan Strike it is represented by a stylized shield.
In Halo Infinite, the name was changed to Nightmare and it is represented by more of a golden eight pointed star, with the middle being completely red, and a sort of "face" overlayed on top.
Trivia
- Earning this medal in Halo 2 will result in the announcer proclaiming "Unfrigginbelievable!", which was eventually turned into a medal in Halo: Reach.
