How often should you get ambushed in the streets? because i cant make it to the other locations without getting killed or sent off to be a slave. I know this game is supposed to be hard, but for me its simply unplayable. 

stay on road will get less ambushed.
higher STA = higher chance to escape.
if u cant escape from encounter. try hide >> enter map. ,and then enemy force will seperate. >> run to edge as fast as u can and leave the map.
