I was playing Halo: Combat Evolved on Coop campaign, the second level. And as I was driving the warthog, the whole thing exploded, like a human explosion, like if a rocket was thrown, followed by about 10 plasma like explosions, and another rocket like one. And both of us were in the warthog so it couldn't have been that. The first thing I said is it is like those creepy stories you here about ghosts in Halo.
