Mission 20
I couldn't even knock dude into the puddle and those water towers kept getting blown up before I could use it on him. After so many retries I just called the chopper ahead of time at a distance and knocked him down with the rocket launcher, ran to the LZ and flew out of there.
All his fireballs got blocked by a tree his was standing too close to.
fukk that dude.
you can wait til it starts raining for an auto win if you have too. I just went 5 ft from the heli pickup spot. Lured him to the top. Dropped the water tank on him and hopped on asap. Started clappin at him with the mounted machine gun to stagger him from taking the chopper out. Took me like 5 tries though
