The Splatter Spree medal resembles a wheel on top a four pointed steel star in Halo 3 & Halo 3: ODST, or a yellow road sign of a black stick figure split in half with entrails and blue blood pouring out on top of a four pointed steel star; it is awarded to individuals after killing 5 opponents in a row without dying using a drivable vehicle on multiplayer matchmaking, or Campaign in Halo: Reach, or Firefight. The Splatter Spree medal is the first of the vehicle spree medals. This medal can be awarded on any gametype containing a vehicle.
- The easiest playlist to earn the Splatter Spree medal is Big Team Battle. This is due to the maps containing a large number players and vehicles, and being large enough to avoid power weapons. Players should try to obtain an agile vehicle such as the Ghost or the Revenant and use the Covenant vehicle boost ability to run players over whilst maintaining an avoidance to danger.
