I'm at a part in the story where I can't be detected but I have to eliminate two guards simultaneously.
I walk up right behind them with my hidden blades but he just keeps killing one at a time. I know they are close enough to do a double. --- GT: Red Undead Now Playing: Borderlands 2, Assassin's Creed 3 http://m-102.minus.com/ipPaN0GZBXpqY.gif
As mentioned you can do air or running double assassinations easy enough but if your looking for the double stab in the throat thing like Ezio could do i dont think you can. However, if you walk up to them and go high profile mode before stabbing them, Conner will do a cool double assassination where he stabs one and turns with is other hand to stab the other. Just remember to go high profile first and it should work.
