This page of the Far Cry 6 game guide contains a walkthrough of operation Surgical Strike, one of the main missions available in El Este. The following guide explains how to sabotage the sub-stations, where to find the computer in the refinery, how to hack the control panels and how to destroy the main device in the refinery.
- Talk to Lucky Mama
- Destroy the poison production sub-stations
- Reach McKay's chemical plant
- Access the computer
- Protect the computer while Yelena hacks the refinery system
- Hijack the control panels on the basin platforms
- Destroy the Toxiflo Reactant Ultrafiltration Downstream Osmometer
Talk to Lucky Mama
You can proceed to this operation after completing the Tourist Trap main mission. You have to meet up with Lucky Mama. You will find her on the upper balconies of the tower pictured in the screenshot - use the long ladder to reach her.
Destroy the poison production sub-stations
You will receive pictures from Lucky Mama containing a map of the pipelines that carry the poison, as well as a sample sub-station. However, you don't have to study this map very closely or worry about having to sabotage all the numbered sub-stations in the picture.
The action plan is simple - travel along the pipeline, which you'll find after going down the tower using the rope with Mama. If you don't want to get lost, the easiest way is to run on the big pipes.
The pipeline will take you to more sub-stations and you will have to sabotage each of them in some way. The main types of sabotage are:
- Interacting with switches (screenshot no. 1) - if the location is large, you may need to find more than 1 such object.
- Destroying yellow poison tanks (screenshot no. 2) - for example, you can shoot them with a gun.
Explore each substation until the yellow search area disappears from the radar. This will be a sign that you have completed all the sabotage-related objectives in the area.
Eliminating all enemies guarding each sub-station is optional, but it may make it easier for you to carry out the actual sabotage.
You need to continue sabotaging the sub-stations until you receive the next mission objective.
Reach McKay's chemical plant
The La Joya Chemical Plant will be the final location of this quest and a pipeline will lead you to it. From a distance, you will see red fumes hovering over the plant.
Access the computer
The chemical plant is a large and heavily guarded location. We recommend stealthily eliminating the nearby soldiers, otherwise you may find yourself under heavy fire or additional enemies may appear.
You will find the computer in the central part of the factory, not in the main building, but in the blue office-container pictured in the screenshot - it's an area with tanks and numerous balconies.
Protect the computer while Yelena hacks the refinery system
If you have already disposed of the nearby enemies, this task shouldn't cause you any problems. Otherwise, expect them to head your way and make sure to follow the radar indications.
Hijack the control panels on the basin platforms
You will need to sabotage 4 panels and you can reach them in any order. After interacting with each panel, stay in the area for a while to prevent any of the newly arrived enemy soldiers from reaching the panel and reversing the hijacking procedure.
Expect enemy helicopters to appear over the chemical plant while you are hijacking the panels. You can either try to avoid it by sprinting and hiding behind indestructible cover, or have it shot down or sabotaged (with the Volta supremo).
Destroy the Toxiflo Reactant Ultrafiltration Downstream Osmometer
Despite the complicated name of the device, the final mission objective isn't overly complex. To begin with, reach the central building of the chemical plant.
Your task is to find and destroy the shiny valves just like the one in the screenshot, but spotting them may require standing in unusual locations or using the balconies inside the building.
Each valve you destroy will weaken the device's percentage energy bar (upper left corner of the screen). After its value drops to 1%, shoot at the main tank to destroy the device once and for all. After a moment, the operation will be complete.
