Ghost of guardian

There have been people claiming to have seen a green, transparent Spartan on Guardian. On January 6th 2008, a lone elite was stuck in Guardian next to the active camouflage power-up. He was offline. Two players were playing by themselves in a slayer game, one saw a figure go around a corner. Later the player saw a spartan with a rogue helmet slide on the floor and the spartan stuck him. At the time they were both elites and nobody had joined the game.
