Gravemind (medal)

The Gravemind medal is a Halo 4 multiplayer medal exclusive to the Flood gametype. It is awarded for singlehandedly killing every Spartan in one round. Contrary to the medal's description in-game and on Halo Waypoint one does not need to do this in only one life without dying. In actuality, the player may die between infections, but so long as they infect every Spartan in the round they will receive this medal.

Trivia
If a player earns a Gravemind medal they will not earn a Final Conversion medal for killing the Last Man Standing.
