Beyond cries from fanboys for Recon, the rarest of all Halo 3 armor permutations -- or at least the rarest option -- is strutting around multiplayer matches with a flaming skull. Originally only available to employees of Bungie, the heated helmets are now the prize for G4's upcoming Sarkathlon.

In order to enter the contest, which runs until midnight on November 8, players must download a special variant of the map Longshore (only found on the second disk of Halo 3: ODST) and find eight hidden grenades scattered throughout the map. The player who completes the task and crosses the finish line in the shortest amount of time with saved replay proof walks away with the flaming skull. It's the Halo equivalent of painting a giant bulls eye on your back, so why wouldn't you want it?
