How to unlock the They Wear Red Bandanas achievement in Desperados III - Definitive Guide
There are 2 Long Coats standing next to each other.
Use Gattling gun, save, kill them and load, rinse and repeat..
There is a badge for not using the Gattling Gun. Make a manual save before even touching the Gattling gun, else it will void the badge, even if you didn't shoot yet. (if you go for this badge of course).
Long Coats will be introduced in the third mission, "Troublemakers in Flagstone". Hector is the only one who can take out these enemies on his own.
You will most likely earn this trophy naturally while going for the other trophies. If you haven't, you can easily farm the Long Coat in the third mission, "Troublemakers in Flagstone", over and over.
Alternatively the fifth mission, "The Magnificent Five", contains a lot of Long Coats, but requires a lot more time to set up.
Note: Statistics like these are almost instantly updated. This means you can create a save, kill (a) Long Coat(s) and then reload your save. You might want to wait 5 seconds or so for the game to properly register this information.
