Quickly follow Price down the catwalk.

ENEMY INTEL #45:
Don't miss this Intel, which is found immediately to your left before getting on the boat.

What follows is an intense chase over the river.  The first part focusses on enemies firing from the sides; There's not much you'll need to do here except to steer the boat smoothly through the river while stepping on it.  You'll sail through a small cave which may be tricky for a short while, though it's not a very long cave.

With the choppers moving in, try firing while steering the boat, and evade any gunfire from the choppers with evasive manoeuvrers.  Keep the boat steady at the far and of the river so Price can get a clear shot and a scene will play.

When you come back to consciousness, move to the chopper and waste the two wounded soldiers you come across.  Follow Shepherd through the sandstorm and attempt to melee him.  A scene will play, during which there are three moments in total where you'll have some control over the situation.  The first moment is when you must attempt to grab the gun - follow the on screen button imputs.  The second moment is with the knife, the third follows immediately afterwards.

Simply aim the crosshair at Shepherd and throw the knife to end the game.

Note: After beating the game you unlock the Museum level, which is listed as a separate act.  You can walk through the museum as played during the credits, and you can shoot anyone you like, with any weapon you like.
