Derailed Extraction | Walkthrough Just Cause 3 Guide

Attach yourself to Teo's helicopter.

At the beginning you will have to go through quite a long cutscene, during which you will learn that General Di Ravello is trying to move a huge cargo of bavarium via train - as you can guess, you must prevent that from happening. As soon as you regain control over Rico, attach yourself to Teo's helicopter, who will take you to your destination.

Wait for the train to be directly below you and then attach yourself to it with your rope.

After a short while you will reach the destination and a train will appear below you - you must get on its board. At the rear end of the train there's a single enemy, stationed behind a HMG - take him out as soon as possible, because he will become annoying later on. After a short while a small group of helicopters will enter the area, trying to destroy the train.

The result of attaching a helicopter to the mountain is quite obvious...

You can deal with them via several means. You can hijack one of them to get rid of the rest, but it's not very effective, as the train will quickly get away from you, resulting in a failed mission. Another method is to simply use your special weapon (the best one here is the Leech rocket launcher, thanks to its homing mechanism) - you can also take them out with the help of your dual tethers, by attaching one end to the helicopter and the other to the ground, resulting in almost instantaneous crash of the said vehicle.

You have to shoot the link holding the wagons together to save the train.

After entering another tunnel you will be given information that another train is closing on your position from the back, trying to crash into the one you're standing on. To prevent this from happening, go to the penultimate wagon and shoot the link holding the wagons together. By doing so, you will detach the last wagon, which will take out the machine closing on you from behind.

And here's the bavarium-filled train.

Afterwards, you will have to deal with another wave of helicopters and a second train coming from behind. When you're done, take out the remaining helicopters and after a short while Teo will inform you, that your main target, bavarium-filled train, is coming from the front. Wait for it to get closer to you, board it with your grappling hook and fill it with explosives. Afterwards, jump off the train and trigger the planted bombs, which should take out the train and end the mission.
