The Mmmm… Brains medal resembles a skull superimposed on a green circular background on top of a five pointed bronze star; it is awarded to individuals after killing 10 humans in a row without dying in Living Dead on Custom Games. The Mmmm… Brains medal is the second of the infection spree medals on Halo: Reach, and the last of the infection spree on Halo 3. This medal can only be awarded on Living Dead.
