This film features my sister (dragonus maximus), my dad (bone chiller), and me (divine winds), and our first attempt at marathon 2 cooperative play.  This film is amusing in spots because we all have different styles.  I tend to me more aggressive than i need to be, my sister tends to stir up all the aliens, then make me kill them, and then get in the way when i'm killing them.  My dad is a decent player, but seems to hold a grudge against the "run" button.  He knows his way around, though, and tends to be our tour guide on most levels.
