Still, if you’re running raids regularly in The Blue Gate, the key is a worthwhile investment of inventory space. The guaranteed material pickups alone make each cellar visit profitable, and you never know when you’ll grab a grenade or extra attachments that can turn a rough fight in your favor.
Final Tips
Use the key during Night Raids for the best loot quality.
Approach cellars near Raider’s Refuge with caution-expect raider encounters.
Always clear the surrounding area before entering cellars to avoid ambushes.
Keep the key in a safe pocket so you don’t lose it during combat deaths.
The Blue Gate Cellar Key is simple but surprisingly useful, especially when you know the most reliable cellar locations. With multiple hatches available across The Blue Gate and steady crafting supplies inside, the key offers consistent value for any player navigating this early-game region.
How to Complete the Cold Case Quest in Arc Raiders
The world of Arc Raiders is full of volatile encounters, shifting extraction routes, and hidden loot-so when a quest offers a chance to wrap things up quickly, it’s worth taking advantage of it. One of the earliest missions you’ll encounter in Stella Montis, the game’s first post-launch map, is a mission called Cold Case. At first glance, it looks like a lengthy scavenger hunt: you’re told to search the urban ruins of Stella Montis for a J Kozma storage container, retrieve a certain quest item, and then safely extract back to Speranza.
Fortunately, the quest is much simpler than it appears. There are multiple Kozma containers scattered throughout Stella Montis, but one of them is located in an unusually convenient spot-mere steps from an extraction terminal. With the right approach, you can complete the entire mission in just a few minutes.
This guide walks you through where to go, what to look out for, and how to extract safely so you can clear Cold Case efficiently and get back to raiding.
Before You Begin – What You Need to Bring
Cold Case has one requirement that players often overlook:
You must extract the ARC Raiders Items you find inside the Kozma container.
That means you’ll want to bring a loadout that includes:
A safe pocket – If another raider ambushes you before extraction, losing the quest item will force you to start over. Storing it in a secure pocket gives you insurance.
A mid-range or defensive weapon setup – The extraction point is relatively close, but encounters with players or ARC units can still happen.
A mobility tool – Anything that helps you reposition quickly or retreat to cover can make extraction dramatically safer.
While the route for this quest is extremely short, the game is unpredictable. Treat Cold Case like any other run: go in prepared.
Where to Find the J Kozma Storage Container
All J Kozma storage containers spawn exclusively on the Stella Montis map, and you may come across several during a regular raid. However, the most reliable-and by far the easiest-location is inside the Lobby Metro Station, one of the map’s primary underground points of interest.
This location is perfect for Cold Case because:
It contains a guaranteed Kozma container.
The container sits right beside the metro extraction button.
The entire interaction-from pressing the button to opening the container-takes place in the same small room.
If your goal is maximum efficiency, this is the only location you need.
How to Reach the Lobby Metro Station
Once you deploy into Stella Montis, make your way toward the Lobby Metro Station marked on the map. The entrance is hard to miss: look for a partially collapsed structure leading into the underground metro tunnel system.
Every player needs a lot of ARC Raiders Coins, I suggest you go to a third-party website like MMOexp.com to buy, safe and comfortable transactions, and years of experience to ensure the security of your account.
