Project Illapa is a large part of the central theme of Just Cause 4.
Map of Project Illapa facilities

Map from the mission "Illapa Project" that shows the approximate locations of the bases.

There is also a location called Illapa and missions with the names The Illapa Project and Operation Illapa. This article is about the project itself.


Mira Morales explains in the first mission of the game that the people of Solís are told and believe that the project is for peaceful purposes.

As explained on the Solís Hoy radio, Oscar Espinosa explains in his autobiography that he started the project 20 years ago when his father Leon Espinosa was killed in an accidental plane crash that was caused by a tornado. He wanted to control weather to eliminate extreme storms, like lightning storms, sandstorms and tornadoes.

This claim is proven a lie by the events of the game, where it's instead explained that Oscar wants to use controlled and weaponized storms.

In the mission Meeting Lanza Morales, it is explained that the project was actually in secret development for a number of years before Oscar took over. The original purpose was indeed to prevent extreme weather, but Oscar ordered it to be weaponized, so he could sell it to the highest bidder.

During the events of Just Cause 4, the project is the highest priority for the nation and most of the industry (that isn't producing weapons and vehicles for the Black Hand) is dedicated to this project.

The project has four main research bases: Zona Uno, Zona Dos and Zona Tres, and one major base at Illapa.

The main storyline missions are about preventing this project from being completed.

Project development historyEdit

Quote from a loading screen: "Thanks to Espinosa investment in weather technology, Solís boasts the worlds best higher education programs for meteorology and climatology."

As explained in the mission Agency Distress Beacon, the project was started at least 30 years ago. This is when the Agency set up a hidden surveillance station next to Zona Dos, to keep an eye on the activity there.

The main weather machine at Illapa was developed by Miguel Rodriguez, a scientist who worked at Zona Dos.

They were, before any actual weather site was built, searching for a site to build a weather core. While their first choice, Isla Santuario was already having foundations for the project laid in, they decided to abandon the site, as the sands shifted too much, causing instabilities throughout the facilities. So they then decided to set up their first core at Zona Uno.

As explained in the mission Meeting Lanza Morales, Zona Uno was the first successful weather machine and Miguel and Lanza Morales (another scientist) had both been working there for a while.

When Oscar took over the companies and projects from his father, he ordered the project be turned around from civilian applications to a super weapon. This made Miguel leave and go back home to Medici. As estimated by Lanza Morales (another scientist), this set the project back by a whole decade. Oscar feared that Lanza might leave too, so he ordered him arrested and placed in the La Mazmorra prison, where he was made to continue his work.

The mission César's Theory explains that there was a tornado at Nueva Voz 10 years ago and another one soon after at Mina Vendeval were accompanied by suspicious activities from the Black Hand. Apparently they had started constructing wind cannons to divert the tornadoes already before the tornadoes hit.

This is confirmed by a caller on the Solís Hoy radio, who also mentions that the wind cannons at Mina Venaval were suspiciously set up before the tornado. That called is then ridiculed by the radio hosts who mock it as a ridiculous conspiracy theory.

The fact that the project is known to have existed 10 years prior to when Leon had his plane crash and that two test tornadoes were sent to civilian settlements imply that Oscar might have used the weather machine to murder his father.

Main base at IllapaEdit

Main articles: Illapa and Operation Illapa.

This is the main weather-machine. The base has three large towers surrounding it on the mountains.

Rico attacks this base at the beginning of the game, but fails to make it to his goal due to the storm and the defensive guns.

Rico then attacks the three wings of the project, the research bases, in order to help Mira destroy the Illapa towers.

The final storyline mission Operation Illapa is at this base and destroys it.


  • It is said in Operation Illapa that the project must've cost the Agency trillions, this raises the question of how Solís, being a relatively small dictatorship, could afford such an expensive project.
    • That speculated cost would only be price asked from the Agency. Considering an unknown profit margin, the actual project cost would be much lower. Also, Solís is gaining an unknown amount of profits from the Black Hand. And also, as mentioned at Solís Hoy, the workforce is very cheap at Solís. And also, most of the businesses at Solís belong to Oscar Espinosa, which allows all companies to save noticeable amounts of money from not having to compete with anyone.
