PowerWash Simulator

In the 5th job of the Warhammer 40k DLC you will need to clean a very large space craft.

Press pause and select the Retro Thrusters so they are highlighted in the game world.

There are 16 to clean, 8 per side and all are on the bottom of the ship.
Again be careful not to go too crazy and accidentally clean something else.

If need be the job can be restarted from the pause menu.

0:00 - We March for Macragge Achievement / Trophy Guide
0:43 - Degrees of Redemption Achievement / Trophy Guide
1:29 - Astra Militarum's Secret Weapon Achievement / Trophy Guide
2:22 - The Emperor Protects Achievement / Trophy Guide
3:43 - Descend into Shadow Rise into Light Achievement / Trophy Guide

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.
