Farming gems at the hardcore level in the Wretched Front location allows you to earn approximately 1,000 gems per hour, without using any modifiers or tickets to speed up. Here are a number of requirements for the successful completion of this task:

1. Make sure your screen resolution is set to 1920 x 1080.
2. Place a Miniganner, preferably a gold one, in the first slot.
3. Add a Scout or Operator in the second and third slots if you plan to gain experience. Juggernaut can be used, but only with an upgraded skill tree.
4. Point the camera at the penultimate bend of the road, placing yourself on the stone from where the player appears, and zooming in on the image by 50% of the maximum.
