i also suspect the first arrow may not of been from the bandits... the angle mark gets shot from is from the farm house NOT the forest
and thats after the fence didn't fry em..
other wise it's a pretty nice coincidence marks gets shot lol
if you kill andy with the fence he seemingly does die but cos of the rain and the generator being damaged and smoking, he seemed to just fall off. but the game does say you killed andy/finsihed him off so logic says he's dead.
