You absolutely have to watch
this user submitted film on Gametrailers. This may be one of the biggest pieces of fan generated film ever...I'm just in awe of this, just amazed at how somebody spent the time to create this film. Outside of the amazing Master Chief/Metroid battle the end is amazing....I'm just at a complete loss of how to describe how awesome this video is.
