Quite often throughout the game you'll come across pallets of barrels suspended above the ground by rope. You can cut the rope by using a throwing knife or being right above the barrels and pressing (Circle on Playstation). Any enemies underneath the barrels will be killed. For this trophy, you need to kill three enemies at once with barrels. While there are no doubt lots of places in the game to do this, the first good opportunity you'll have is in Sequence 4, in the memory Unnatural Selection. At the start of this mission you'll be tasked with opening a large factory door. Right in front of the door are two enemies standing underneath a set of barrels. Get yourself into knife-throwing range and wait. A third enemy will wander just inside the kill range of the barrels. Drop them using a throwing knife and you've got yourself a trophy. ---------------------------------------------------------------------------------------------------------------- Assassin's Creed Syndicate Trophy/Achievement Guide: http://psnprofiles.com/guide/3478-Ass...
