You control both characters. Drake drives while Elena wields a 92FS-9mm. Elena 's gun has unlimited ammo in this chapter.
Explosive cans are throughout the river. You can either choose to avoid them or to slow down and shoot them before you run into them. Running into them will cause instant death. However, Elena can blind-fire now, so you can hit the barrels and keep going forward simultaneously. Some of Eddy's pirates are along the banks of the river, so be ready to shoot while you drive the jet ski.The jet ski is not the easiest vehicle to drive, especially when going upriver. When you get to the point where the pirates are eliminated and music is still playing, the difficult upstream river part comes in where the explosive cans are now actually rolling downstream towards you, so try to avoid being hit. This part includes you driving the jet ski up onto higher landings.
After taking out the last set of enemies, drive up to the tunnel to reach the monastery, then head for the drop-off point ahead.
