Kinshasa: Extended level:
     At the end of the ninth mission, Kinshasa, when you have a sniper
to  shoot  Hamza Hishima do not shoot him. If you do you will complete
the  mission. If you do not, the crane you are on will fall down. Then
Emile  will yell at Sam for missing Hishima. Sam angrily turns off his
radio and the level in now extended for several minutes.

Kinshasa: Secret tool:
     At  the  beginning  of the mission you must go up a elevator. You
will  then  get  a  checkpoint. When you enter this room, take out the
guards.  Make  sure you are not wearing your sunglasses. When you walk
in  the  next, big, room, the sun should be shining in your eyes. Flip
your  glasses down and you can see guards shooting out the windows you
were  looking  at.  Go to the right as soon as you walk in. Try not to
draw too much attention. If you keep going to the right you will hit a
window.  An icon should appear at the bottom of the screen, indicating
that you can use something. Press X and Sam will get out a small black
tool,  clip  it  on  the window, whiz it around, then pull off a small
circle  that  he  has  cut from the window. If you push forward on the
window,  Sam will put his legs through and squeeze through the hole so
that he is now outside.
