Pursue Amanda

Rio del Jade

You'll start at the boathouse from the last mission as guards begin to swarm in. Since there are two exits from the area, you can simply head south to avoid them altogether. Alternatively, sneak to the left and make your way to the northern exit.

El Cenagal

There are only a few guards patrolling the jungle, making them easy targets for a CQC grab or throw. However, there is a narrow bridge ahead, and a soldier that will pace across it. When his back is turned, climb over the railing and shimmy across to the other side and make your way to the factory.

Bananal Fruta De Oro

The area is crawling with soldiers, so it's best to make use of your tranquillizer gun. This is also a good time to make use of the Fulton and kidnap fallen soldiers into your army. There are also POWs hidden in the area that can be saved via Fulton recovery. To finish the mission, take the back alley way to the north-west, backtrack to the east, and make your way to the exit in the north.
