Descend into Shadow, Rise into Light Achievement in PowerWash Simulator

This is completed during the final job of the DLC, the Thunderhawk. On this job, you need to clean all of the Retro Thrusters before cleaning anything else. There are 16 of these in total and they can be completed in any order as long as nothing else is completed in between. You can pause the game and select them from the to do list to highlight them in game.
