The Running Riot medal resembles a silver and purple bulls-eye target sitting on top of a six pointed silver star; it is awarded to individuals after killing 15 opponents in a row without dying on multiplayer matchmaking, or after killing 30 opponents in a row without dying on firefight or campaign in Halo: Reach and Halo 3: ODST.
The Running Riot medal is the third of the spree medals in Halo: Reach, Halo 3, Halo 3: ODST, and Halo 4. This medal can be awarded on any gametype, and has a Bungie rating of 8/10 - meaning this medal is of high difficulty to achieve. This medal goes hand in hand with the Perfection medal.
- The easiest playlist to earn the Running Riot medal is Living Dead as all the opponents wield energy swords requiring them to come close to the player to infect. This allows players to either kill the zombies from a distance using a pistol, or kill the zombies with ease using the shotgun.
- Another playlist which displays relative ease to earn the Running Riot is SWAT. This is due to players having no shields, and only requiring one head shot to be killed. So long as the individual has a keen enough accuracy, and the ability to strafe and dodge incoming fire.
- It has been proven that the highest spree possible is 255 kills. Even if you get more kills after that number, without dying, it will still say that your highest spree was 255 kills. This is most likely because 255 is the maximum value representable by an eight-digit binary number, and therefore the maximum representable by an unsigned 8-bit byte.
