The Splatter (Roadkill in Halo 2) medal is awarded in campaign, multiplayer, Firefight and Spartan Ops and achieved for hitting and killing an opponent with a vehicle. It is represented in Halo 2 and the Halo 3 Beta by a five-pointed star with a tire in the center (this image was later used for the Wheelman Medal). In Halo 3, Halo 3: ODST and Halo: Reach it is represented by a yellow diamond street sign depicting a person split in half at the waist, imposed on a bronze cross. In Halo 4 the sign is imposed on a grey 4-pointed star. In Halo 5: Guardians the medal consists of the street sign only.
This medal is accompanied with the message, "You splattered (player)". It is also possible to splatter a player with an object by launching it with an explosive, using a Gravity Hammer, or by launching a large object through a Man Cannon.
