View Metroid Prime Hunter Trailer in First Hunt
     To unlock the Trailer for MPH, you need to place 5th or better in
Regulator,  Training and Morph Ball areas in the Single Player part of
the  game.  When  you do get 5th or better on each one, it will prompt
you  to view the trailer. After you view it, you can view it any other
time  by  going  to  the  Main  Menu  (where  it says "Touch Screen to
Continue"),  there  will  be  a flashing dot in the lower left corner.
Touch  that  dot  and  you'll  be treated to the trailer anytime you'd
like. Use the stylus to hit that dot, because using the Thumb Strap is
kind of hard.
