About this guide

This is a short story overview of Just Cause 4 with the main operations in the order the Ludo.guide walkthrough lists them. It is not a full walkthrough and it does not describe how to beat individual missions. The plot summary follows Wikipedia.

Step 2 of 7
Story setup

Rico Rodríguez travels to Solís, a fictional South American country, after learning that his late father Miguel worked on the Illapa Project, a weather weapon run by Oscar Espinosa. Rico builds a rebel force, the Army of Chaos, and opposes the Black Hand, a private military led by Gabriela Morales.

Step 3 of 7
Core tools: grapple, wingsuit and weather

Rico moves with a wingsuit and a grappling hook that can attach hot air balloons and rocket boosters to objects. Dynamic weather such as tornadoes and thunderstorms affects travel and combat, and the Frontline system lets Rico join rebel battles.

Step 4 of 7
Opening operations

The Ludo.guide list begins with Operation Whiteout (Casquillos Vacíos Reboot), then the Agency Distress Beacon and the Illapa Project missions. Behind the Lines, a Sargento mission, is where the first grapple mod is introduced.

Step 5 of 7
Mid-game operations

The list then moves through region missions across the map, including an Operation Windwalker entry and a Thunderbarge operation (Obtaining the Ion Coil, Meteolab Grab and the Ion Coil Delivery Operation). The listing gives titles and locations, not descriptions, so we do not describe what happens in them.

Step 6 of 7
Late operations and the finale

The late list includes Sandstinger (Train Robbery, Torretas Takeover, then Operation Sandstinger) and ends with Operation Illapa in Qachas. In the final assault, Gabriela turns on Espinosa and Rico uses the last weather core to destroy Espinosa's jet.

Step 7 of 7
DLC

Wikipedia lists three DLC packs: Dare Devils of Destruction (30 April 2019), Los Demonios (3 July 2019) and Danger Rising (5 September 2019).
