Time for an Upgrade | Walkthrough Just Cause 3 Guide

First, you should train the ability to open the parachute when using the grappling hook. You will do it by opening the parachute after attaching yourself, when Rico is moving towards the object to which the rope is connected. Do it twice and then walk towards Dimah.
Attach the rope to the barrel and the gate in the base (you will do it by holding the button responsible for shooting after the first use and then by aiming at the gate). Use the same mechanism inside to pull red barrels to the fuel tanks. Finally, on the left side you will find two generators. If you don't have any barrels left, you will find few of them near the gate. After destroying all objects you will take control of the base. Go back to Dimah.
Once the conversation is over, jump down the edge and open the wingsuit. Control it in such way that it will not lose altitude (the button responsible for going back) and fly towards the bridge where you should open the parachute and land. You can land not precisely there and simply run towards the destination. Select the explosive and plant it in two marked locations.
Then, walk towards the viewpoint. Observe the convoy and activate the bombs when the vehicles will drive on the bridge. Through the radio, Dimah will give you next instructions and will mark the location of two launchers on the map.
In both places the matter is very simple - the rocket launcher is protected by a single enemy. Kill him, walk towards the panel and start the hacking (interaction). Do the same at the second launcher, which is more far away from the viewpoint.
Now watch as rockets hit the enemy helicopters and go meet with Mario.
