The Double Kill medal is awarded for killing two opponents within four seconds of each other in standard Multiplayer games and within less time in campaign and Firefight. In Halo 4 multiplayer and Spartan Ops the kills need only be within 4.5 seconds of each other.
The medal was originally represented by two blue stars in a yellow circle. In Halo 4 it is represented by two white stars on a navy blue circle, rimmed with blue and brown. When someone attains and achieves this medal, the announcer will shout "Double Kill!" to the player as the "Double Kill!" medal appears in their HUD. In Halo: Combat Evolved due to a lack of visual medals however, the words "Double Kill!" will appear in the upper right corner of the screen.
