Splatter

The Roadkill (or Splatter in Halo 3) Medal is awarded for hitting and killing an opponent with a vehicle. It is available in all Multiplayer gametypes where a vehicle is available and has a Bungie difficulty rating of 1 (out of 10). It is represented by:

• Halo 2: A five-pointed star with a tire
• Halo 3: A cross with a person's waist snapped apart

After you hit and kill an opponent with a vehicle, a message will appear on your screen that says: "You splattered (player)". This is also a medal in Halo 3 campaign. It is also possible to splatter someone by launching a large object at them with a explosive, or gravity hammer. You can also splatter someone by launching a soccer ball/cone etc. by using a man cannon.

If you are playing Halo 3, it is much easier to get this medal with the Ghost than any other vehicle, because of its speed and maneuverability. However, it is easily jumped over.

The Halo 3 medal also resembles the "Bob-B-Q" medal from Marathon: Durandal.
