Nitro - From Dust Walkthrough (Challenge Mode)
Challenge Mode Walkthrough - Level 21
"Spilling the beans is your quickest way to defeat."
I'm not convinced my method is the best, but regardless, what you want to do is use the water to put out the fire and protect the village. Put a few explosive trees at the top of the path leading from the water to the village and put a few around the village so they create a dip for the water to move. Keep a good watch and use trees to slow down any fire getting too close to the village.
