The Greasing Her Palms quest marks one of the first challenging objectives in ARC Raiders. You must find three locations in the Dam Battlegrounds, Spaceport, and the Buried City maps with just a few clues.
Here’s a complete guide on finding all the locations needed to finish the Greasing Her Palms quest from Celeste in ARC Raiders.
All Greasing Her Palms Objective Locations in ARC Raiders – Dam Battlegrounds, Spaceport, and Buried City


To finish the Greasing Her Palms quest, you must complete the following objectives:
- In Dam Battlegrounds, visit the Locked Room in the Water Treatment Control building.
- In Spaceport, scope out the rocket thrusters outside the Rocket Assembly.
- In Buried City, visit the barricaded area on the 6th floor of the Space Travel building.
This is one of the first quests that requires you to go to different maps to complete. However, it is as easy as navigating to a specific location, where one location requires a specific key. Some of these spots could take a while to run into, especially when you have a bad spawn relative to the quest locations.
You can also expect these places to be frequented by players who are either doing quests or just looting.
Locked Room in Water Treatment Control Building Location – Dam Battlegrounds


The locked room in the Water Treatment Control building requires the Dam Surveillance Key to finish the objective. When you get the Greasing Her Palms quest from Celeste, you get a Dam Surveillance Key just by accepting it.
Put the Dam Surveillance Key in your Safe Pockets so you never lose it when you die before reaching the spot. Go to the Water Treatment Control, as seen in the map above. Go to the south side and enter from the ground floor instead of the top floor.



Once you enter from the main entrance on the ground floor, head to the first hallway to the right. Turn right again, and you’ll see a locked door that requires the Dam Surveillance Key. Open the door and just step inside to finish the objective. If you die during the raid, you won’t lose the objective progress, so you just have to make sure you step inside.
If, for some reason, you lost your Dam Surveillance Key, you should try looting areas with “Residential” loot. These areas give trinkets and keys more frequently. These are some of the best items to loot since they either give a lot of Credits or give you keys that open locked rooms that have a lot of valuable loot, especially blueprints.
Inside the Dam Surveillance room, there are a lot of lockers and containers you can loot, along with a lot of loose loot around the command tables.
Rocket Thrusters in Rocket Assembly Location – Spaceport


The Rocket Thrusters in Spaceport are in a tough spot. It is directly outside the Rocket Assembly and situated in the middle of a wide, open area accessible from the Control Tower, Container Storage, and the Rocket Assembly.


However, you just need to step in the middle of these Rocket Thrusters to finish the objective. You can run to the Raider Hatches to the east, assuming you have a Raider Hatch Key. If not, you should run as fast as you can for cover and go to the nearest extraction.
There are several ARC enemies that roam around the open area. A Snitch could even spot you and call an annoying Leaper that could destroy you, and also announce your presence to everyone in the area.
Barricaded Area Space Travel Location – Buried City


The last objective is the Space Travel building in the Buried City. This is one of the hottest areas in Buried City, comparable to the Hospital, as these areas contain high-value loot. The Space Travel also holds Commercial and Technological spawns like Wires and Batteries. Players tend to loot these areas to find most of the materials needed to fully upgrade their Workshop.
To finish the objective in a much safer approach, you can go to the Research building in the other building. These two buildings are next to each other, and there’s a bridge on the rooftop you can cross to enter the Space Travel building.



Head to the staircase and go to the 6th floor. Follow the hallway to the center and go inside the barricaded room to finish the quest.
You can also approach the Space Travel normally, as it has multiple entrances. It is up to you how you want to approach this dangerous building. You can go to the first floor and work your way up the staircases until you reach the 6th floor, or go from the rooftop.
After finishing the objective, you can also loot the same 6th floor since this area practically holds most of the loot in the Space Travel building.
