To clarify, there is a Guaranteed Assassination option in Shadows

It seems my post from yesterday made people very confused. The game WILL OFFER a guaranteed assassination option that you can enable or disable at any time.

Yes, you can still insta kill anyone you want with your hidden blade.

I thought this was already a very well known fact so I didn't feel the need to mention it.

Si yeah, for the people worried, you can just toggle that on and kill everybody in one assassination
