The Stick Spree medal is awarded in Halo: Reach and Halo 3: ODST Firefight for sticking five opponents in a row without dying. This can be done with either the Plasma Grenade or, in ODST, the Spike Grenade. It is represented by a four-pointed silver star with a blue orb in the middle. In ODST the medal is easiest to obtain on the ONI Alpha Site Firefight mission because of the map's close quarters. Given their size, aiming for Brutes is recommended. In Reach, Waterfront and Courtyard are good for the same reason.
