Double Kill medal

The Double Kill Medal is awarded for killing 2 opponents within 4 seconds of each other. It is available in all Multiplayer gametypes and has a Bungie difficulty rating of 5 out of 10. It is represented by a brass and golden circle with 2 blue stars in the center of the circle. When someone attains and achieves this medal the announcer will shout "Double Kill!" to the player that received this medal. In Halo: Combat Evolved, because there are no medals, if a player kills two opponents within four seconds of each other, they will still hear the announcer, but instead of the medal they will see the words "Double Kill!" in the upper right corner of the screen. It is the most frequently earned multi-kill medal.

Trivia

 * This is one of the easier medals to get, and the easiest of the multi-kill medals.
 * With the Legendary update, getting two of these in one game on a Legendary Map in Halo 3 will get you the achievement Double Double.
