Mmmm.... Brains (Halo 3)

In Halo 3
The Mmmm.... Brains medal is awarded when a player infects 10 Humans in a game of Infection without dying. Progress for this medal does not carry over between rounds. There are only a few cases of video evidence of people earning an Mmmm.... Brains medal in Halo 3.

In Other Games
The Mmmm.... Brains medal so far has only appeared in one other game, Halo: Reach.
