Splatter Spree is a spree medal awarded in Halo 3, Halo 3: ODST and Halo: Reach for splattering 5 opponents in a row with a vehicle without dying. It is represented by a steel four-pointed star with a tire in the center of the medal.

The two best vehicles to achieve this medal with are the Ghost due to its maneuverability and the Brute Chopper because of its sheer size. It is also possible to use the plasma guns halfway to achieving this medal, as it won't reset the amount of splatters needed. Also, if the medal is earned on a Legendary map pack map, the achievement Look Both Ways will be unlocked. In Halo: Reach, the medal requirements are made easier since the player can get all five splatters in a single life and without them having to be done in a row.

Splatter Spree medals seem to be glitched, as after gaining a Splatter Spree with a vehicle, you gain a Splatter Spree for every kill you score with your vehicle's main guns. This is also the case with the Vehicular Manslaughter medal as well. Gunners and passengers' kills are excluded.
