SmuggleCraft

This will actually be easier than it sounds. While going through the Campaign, play the Story Missions as soon as they appear (the blue triangles). Depending on what decisions you make, there will be anywhere between 5-10 Missions to complete. You will still have to pay off your debt to Garmuk 2-4 times so make sure you have enough credits to do so.

Complete all the Story Missions without entering the Upgrade Menu and the trophy will unlock during the End Credits.
