Killionaire

Killionaire is a multikill medal awarded in Halo 3 Multiplayer for killing 10 opponents within 4 seconds of the previous kill. Unlike Halo 2's "Killimanjaro" medal, this does not repeat if you kill 11+ opponents withing 4 seconds of the previous kill. This is the hardest of all multi-kill medals to achieve. However, when Bungie opened up the Grifball playlist on March 6, the medal became much easier to achieve. This multikill medal is actually shown in the "special" medals row, instead of the "consecutive kills" medal row.

"I Apples I" earned the number 8 spot on the MLG/ESPN Top Ten Halo 3 plays (second edition) by obtaining a Killionaire Medal in a Team Swords match on Snowbound. This is also due to low rates.
