This page describes the Behind the Lines mission in Just Cause 4. This is the first mission for a character named Sargento. In this mission you will get access to the Air Lifter, which is a modification of the grappling hook that allows you to lift objects and enemies using gas balloons.
Beginning of the mission
You will get access to the mission after completing the Operation Whiteout task. Start the map, then find the letter "S" on the map - click on it and choose the option to track the route. The mission goal is quite far away if you decide to follow the main road there. A much better idea is to use the wingsuit. Jump off a nearby precipice, use the wingsuit and head towards the mission marker. If you fall to the ground, continue your journey with a parachute and rope. When you reach your destination, you will see the task marker (letter "S") on the ground - approach and activate it. This way you will start the mission.
Escorting a truck
Your main goal is to escort a truck. Jump on it and your journey will begin. At some point you will come across a blocked road. You will now have access to the first modification of the grappling hook, the air lifter. Start the map and then enter the hook menu. Set up the air lifter according to the game instructions and return to game world.
What is air lifter for?
It allows you to attach a gas balloon to the objects, so that they can fly upwards to remove obstacles on the truck's road. Sometimes one balloon is not enough, so just pin more balloons. Using Air Lifter is very easy - use the button to shoot the line and hold it for a moment.
The Air Lifter is not the only improvement of the grappling hook. For more information, please refer to the "How to improve the grappling hook?" section in our guide.
Of course, you can also use the air lifter to fight your opponents. If you attach a balloon to an enemy, he will rise into the air reducing the possibility to attack you. Then you can shoot at the balloon, which will cause your opponent to fall to the ground and probably die.
How to fight while escorting a truck?
You will be constantly attacked by enemies while driving. You can easily cope with infantry using a rifle and simple shooting, but it would be great to use something stronger for enemy vehicles. It's best to use a grenade launcher or rocket launcher. This way you'll quickly get rid of vehicles that chase you. You may fall out of the truck during a fight. Then return to the truck as soon as possible using your grappling hook.
Defending the village
The last stage of the task is to defend the village. The main attack will come from the side of the road. Despite that, smaller units will attack you from virtually any side. It's a good idea to use a nearby launcher to get rid of enemy vehicles. Then switch to normal weapons and knock out individual infantry units. If you run out of ammunition, pick it up from dead enemies. You must survive for about 2 minutes. If the truck is not destroyed during this time, you will complete the Behind the Lines mission.
