This page of our game guide to Control - AWE contains a detailed description of the Another Fine Mess: Clear the Mold side mission. By reading our guide you can find out where the areas with mold are, how to enter them safely and how to get rid of the mold.
How to unlock the quest: you must reach the Operations Center and, after defeating your opponents, examine the bulletin board. This is one of the tasks commissioned by Athi.
Don't start this task if you haven't completed the Old Growth side mission yet. Only then Jesse will be able to freely enter areas with poisonous mold without fear for her life.
Places which you have to visit during this mission are:
- Abandoned Offices
- A/C Systems - you must first begin the second story mission - The Third Thing.
- Loading Bay Vents - you must first begin the second story mission - The Third Thing.
In each of these locations, use service weapons, telekinesis, or other powers to destroy the mold until the progress bar fills up. Help yourself if needed by levitate in order to find mold hidden by the ceiling.
In the Abandoned Offices, the entrance to the mold area is where Jesse has to complete a short climb. This is just before reaching the Operations Corridor.
In the A/C Systems location, you'll pass a room with mold shortly after jumping into a shaft and killing two monsters. It's hard to miss.
In the Loading Bay Vents location, look for the grate which you will pass along the way (as shown in the picture). After you break it down, you can enter another part of the vents where you can find, among other things, a room filled with mold.
