Killionaire medal

Killionaire is a multi-kill medal awarded and achieved in Halo 3 Multiplayer for killing 10 opponents within 4 seconds of the previous kill, this medal is represented as a black hexagon with 10 platinum/silver stars. Unlike Halo 2's "Killimanjaro" medal, this does not repeat if you kill 11+ opponents within 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 can also be more easily achieved through using Team Swords on Multi-Team. This multi-kill medal is actually shown in the "special" medals row, instead of the "consecutive kills" medal row.
