Horizon Forbidden West

There are 4 Salvage Camps out in the Forbidden West (the location of all of them can be found here) and in order to get this trophy, you need to complete one of those sets. The easiest, by far, is the one outside the Daunt (to the west of Barren Light), and you’ll only have to complete 4 Salvage Contracts to net this trophy. 
Those 4 Salvage Contracts are:

• Scavengers
• Convoy Ambush
• Alarm Antennas
• Elusive Fanghorn

Finish those 4 contracts and you’ll get this trophy. Quick note before I move on, it’s actually worth doing all 4 of the camps and then returning to Keruf, as this will net you a fancy piece of Legendary armour, known as the Oseram Artificer. Head to this link for a list of all the contracts you need to do and where you’ll find every Salvage Camp.
