The Jackal will be standing on the main courtyard. He will tell you, that he is planning to help the fugitives, which are escaping from the country. To make this possible, you will have to obtain the suitcase with diamonds. These diamonds will be used to bribe the border guards. Jackal will tell you also that leaders of both faction have meeting in the camp, which is located near of the crash site. He will lead you to the gate, which is leading to this part of the forest. Before you will go there, prepare yourself. If you will pass through this gate, you will have no return.
Start eliminating enemies on the swamps and in the forest behind the prison. When you reach the wide chasm, turns left and enter in gorge. On the end of the gorge you will find crashed plane.
Go on the other side of the chasm. You will find there one of the hideouts and supply of the ammo. Now you will be able to go left, to the merc's camp or right to your friends. If you go left, you will be able to kill two remaining leaders.
In this moment you are friend of the both faction, so you can walk in the camp without any problem. The leaders can by eliminated in close distance or with the sniper rifle. If you decide yourself for the second option, use the dart gun. Earlier eliminate silently snipers, which are located around the camp.
On the right side of the hideout, just near the crashed plane, you will find your friends. Unfortunately this meeting will ends with conflict of the interests. You want to help fugitives, but your friend wants to keep the diamonds. You will have to fight with them. This will be hard task, because your friends are more resistant that ordinary soldiers. You should use the machine gun, which is located on elevation, near the place, where you jump the fence. With his help the fight will be quite short. If any of your friends will be wounded, but alive, you can close to him and finish what you started.
It's time for the next meeting with Jackal. He is waiting for you in small hut. Listen him. You will able to end the game by one of proposed missions.
If you choose the first one, you will have to bring the battery to the hill behind the hut and connect to him the TNT. When fugitives will cross the border, the TNT will explode, blocking the mercs. You can also take the suitcase from Jackal and deliver her to the guards in border outpost. The second mission is visibly easiest than first.
After completing this mission, you will see the outro with information about the fates of the heroes.
