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.

When you enter:

Descend the staircase or the broken escalators into the station.

Follow the lanterns, signage, or platform lights until you reach the metro platform area.

Move toward the extraction call console-the same terminal you would use when leaving the map.

The Kozma container is extremely close, so getting lost is unlikely.

Looting the Container and Obtaining the Old World Books

Once you locate the extraction button inside the station, you're already at the finish line.

Here's what to do:

Press the extraction button to call the train in advance.

This ensures you're not stuck waiting once you've collected the quest item.

After pressing the button, turn around 180 degrees.

Just a few steps behind you, you'll see the J Kozma storage container sitting directly across from the terminal.

Interact with the container.

It will pop open and drop an item called Old World Books, which is the object Shani needs to complete the quest.

Place the books into a safe pocket if possible.

This protects the ARCR Items from loss if another player eliminates you during the extraction phase.

With that, the hardest part of Cold Case is already finished.

Extracting Back to Speranza

The only thing left to do is get out safely.

After calling the metro train, take cover behind one of the nearby pillars, walls, or vending stations.

Even though this location is usually quiet, it's still an extraction zone-making it a prime spot for ambushes.

Listen for the train to arrive. When the doors open, move quickly but carefully.

Step inside and immediately use the onboard extraction console.

Once activated, the train will whisk you back to Speranza, completing the quest and securing your loot.

Assuming no other raiders interfere, the entire process takes under two minutes.

Final Tips for Completing Cold Case Safely

Avoid unnecessary fights in Stella Montis. The longer you linger, the greater the odds another squad shows up.

Call the train before looting the container so you can extract without downtime.
