How to get The Order: 1886 Collateral Damage Gold Trophy

To get The Order: 1886 Collateral Damage Gold Trophy you need to destroy three monsters with a single explosion. 

The Order: 1886 is set in an alternate history London, where an old order of knights keep all of the world safe from half breed monsters, who are a combination of animal and man.

The most easiest way to get this trophy is, trying to get it in the eighth chapter: Under Siege ; Scene: A One Man Army. In this chapter you will get a chance to launch a rocket on the horde of enemies. 

All you have to do is immediately after you take control of the rocket launcher, aim to the bottom right and there will be a group of 3 enemies behind a broken fence. As soon as you kill a bunch of them, you will have unlocked the Collateral Damage Gold Trophy.
