After shooting the electrical box to open the big door, as shown in the previous section, you drop back down into the street here. Next, you're headed for the two staircases to the northeast. You'll probably want the motorcycle now.

To clear the area, first drive up the stairs on the left.

Run over a soldier at the top and continue through the doorway...

...and down the hill, running over another soldier at the bottom.

Notice the huge pile of sand on the ledge above where that second soldier fell. At the top of the pile is a ladder, which leads to the level exit. It's difficult to reach the ladder on foot since the sand pile is so steep. (If you want to try it, see the next section.) But, you can make it on the motorcycle now that you have the nitro upgrade.

In the corner above and to the south of the sand pile is the big door you just opened by shooting the electrical box. You will jump the motorcycle through there.

Start by riding back up the slope...

...and down the staircase the way you just came. Continue up the next hill but not all the way back to the starting area.

Turn around and position the motorcycle near the wall, facing the left side of the right staircase. This will give you a long, straight run-up to the doorway.

Hold Action and Sprint/Dash to activate the nitro boost and race forward up the stairs...

...through the open door...

...up onto the sloping ledge directly ahead...

...and off the other side, landing on top of the big sand pile.

IMPORTANT: Later you will return to this area through the small, metal door in the corner. Do not park the motorcycle in front of this door or you may have trouble getting through.

Climb the ladder and follow the passageway to the next level, STREET BAZAAR.
