Detonate 10 Powder Kegs
The Order: 1886 HIGHLY VOLATILE Trophy Guide
Another trophy where you can make use of a checkpoint in order to get the trophy quickly. Load up Chapter 3 / Scene: The Puppet Queen and you will get to a shootout after a short walk.
There are 3 powder kegs in this area for you to shoot. Reload the checkpoint from the menu and repeat this until you have shot 10 kegs. You will respawn directly before the fight now, which saves a lot of time.
