Congo: Descent Into Zinj Codes -

Hint: Kill Travis:
At the end of the game, before you enter the clearing, save the game. Then, proceed to trick Travis as normal and charge the laser. This time however, do not fire it. Instead, wait until you see Travis' helicopter, and wait for it to hover for a second, when it is about to fly away. While it is hovering, aim the cross-hairs at the helicopter and fire the laser. The helicopter will explode, and you will say, " Goodbye, Travis." However, you will still die.
