There’s more fire to extinguish here, and a local offers a hint on how to accomplish this with a nearby irrigator. Destroy the shield generator, which becomes Multi-Build bricks.
Repair the hoses on the left with the Multi-Build bricks. Bounce on the pad next to the villager until the barrel fills with water. Build a rotary control at the base of the water structure and move the barrel to the other platform.
Break down the rotary control and install a power jack on the large motor to the right. The water from the barrel shoots out and extinguishes the fire below. Either character’s first step near the stormtroopers ends the chapter.
