Killimanjaro

The Killimanjaro Medal (Kilimanjaro, Killimanjaro, Killimanjaro) is awarded for killing 7 opponents within 4 seconds of each other. If you were to get one barely under the time requirements, you would have to get 7 kills in just under half a minute. It is available in all Multiplayer gametypes and is assumed to have a Bungie difficulty rating of 10 out of 10 since the Killtrocity Medal has a difficulty rating of 9 (out of 10). It is represented by a platinum circle with 7 yellow-gold stars. This medal is seen very rarely, and most often in custom gametypes, or in Halo 3 Grifball. Since Bungie has released no information on this medal, an image had to be lifted from a set of post game stats. When someone gets this medal the announcer will shout "Killimanjaro!" to the player that received this medal. The name is a play on the African mountain, Kilimanjaro.

See Killionaire for an easy way to get this medal.
