for chapter 2 simply guide the arrows carefully right beside the man running I forget his name but any way just do that and I reccomend killing the ballista in the tower firstn NOTE: guiding and killing instead of just shooting kills in one hit while just shooting kills in two hits - your welcome, Signed Dakota J.

I was stuck on this part for 3 days and could figure out what the guide meant by using the sqaure button to guide the arrows to hit the soldiers. Everytime I would do it, I couldn't guide the arrows. In the options screen you have to turn off the aftertouch. Once you turn it off, you will be able to guide the arrows. This will give you time to shoot each soldier that come shen's way.
