Wild West Indies Trophy
Wild West Indies
Kill 4 enemies in a row using multi-pistols.
For this trophy you'll first need to completely upgrade Kenway's holsters. You can hunt the required animals or buy the items required for crafting at any general store. You should also buy the "cannon-barrel pistol" to get one-shot kills.
Now all you need is to find a group of at least four or board a ship, select your weapons and press four times without aiming. If you're lucky enough each shot should kill an enemy, if not there are plenty of opportunities.
