Using a Haystack+Whistle in Syndicate
https://youtu.be/f1lquKwdV04
I wasn't planning to make any Syndicate videos, but good use was made during the mission Unnatural Selection of a haystack and the whistle ability, so I figured why not share. Enjoy.
That must be the Marry Poppins bag of hay bales when you're done with it! The horses must be so disappointed with their layer of hay over copious dead bodies.

Bloody awesome stuff, Aurel. 
Could you whistle from Haystacks in AC3/Black Flag/Rogue? I feel like you could but I might be misremembering.
I know you can Whistle from:
- Stalking Zones
- Wall-Lean/Corner Set-Up
- Hiding Doors
So it stands to reason you could Whistle from Haystacks too, but I guess it's striking in Syndicate because it's just a Function you can call upon at any time. Whistle isn't contextual in Syndicate anymore, you can do it at any time. I like that a lot, it makes sense to be able to do that.
Yes. I think you could whistle from haystacks in 3/4/Ro.
Sadly, you can't kill from inside with a distance weapon. I wish you could use the blowgun from a haystack, if only because that's how an Assassin might approach the situation....

You can whistle from haystacks in those games but for some reason it was slightly unreliable. I remember sometimes after whistling the option to assassinate wouldn't show up, in turn forcing me to be detected. Oddly enough this only happened in Black Flag though.
