In the last part of the first DNA section, you're in a small village searching for the Templar leader. The optional objective for this section is to kill 5 enemies from haystacks.
There are a couple haystacks along the path to the final fight, but I wasn't able to get 5 kills from them. There are also haystacks in the final area, but I ended up low on health and surrounded by so many guards that I had to frantically kite and kill them without getting to use the haystacks.
Is it possible to get the 5 haystack kills on the path to the Templar leader, or do you have to get some haystack kills in the final battle of the section?
