The Turnabout quest in ARC Raiders sends you deep into the Spaceport zone on a high-risk intelligence mission. Celeste needs help uploading incriminating blackmail files, and she's counting on you to get them into the North Trench Tower's terminal. While the objective sounds straightforward on paper, the area is heavily contested, loaded with ARC threats, and frequently swarmed by ARC Raiders Coins other raiders looking to complete the same objective-or steal whatever ARCR Items you might be carrying.

This guide breaks down exactly how to complete the Turnabout quest, including where to find the North Trench Tower, how the Spaceport Trench Tower Key works, and what dangers you should expect on approach.

Understanding the Spaceport Trench Tower Key

When you first accept the Turnabout quest from Celeste, she provides you with a Spaceport Trench Tower Key, which is essential for completing the mission. This key must be physically present in your inventory during the raid-you cannot interact with the North Trench Tower door without it.

Because Spaceport is a popular PvP zone and the tower is a known quest objective, it's smart to store the key in a secure pocket before deploying. If you die and drop it, you'll lose the opportunity to finish the quest until you find another key.

What If You Lose the Key?

Finding a replacement key can be a frustrating process:

The drop rate is low and random, like most special keys in ARC Raiders.

Many players report the highest success rates in residential areas, where key spawns appear more frequently in containers and cabinets.

There's no guaranteed source, so if you lose your key, you may need to grind loot zones or rely on luck.

Hang onto your key carefully-losing it means delaying the quest until you're fortunate enough to secure another.

Where to Find the North Trench Tower

The North Trench Tower is located at the far northern tip of the Spaceport map, perched above a trench system filled with ARC patrols and, often, opportunistic human raiders. Because Turnabout is a common quest, it's very likely you'll run into other players heading for the same location.

Expect Heavy Resistance

As you approach the northern edge of the map, stay alert. The area around the tower frequently includes:

A roaming Bastion moving through the trenches

Rocketeers patrolling the air

Human raiders waiting to ambush players entering or leaving the tower

The vantage point around the tower makes it an excellent location for ambushers, so expect gunfire when you get close.

Accessing the Tower: Don't Waste Your Key

Once you're certain you've reached the correct structure-the North Trench Tower-you can use your key to open the entrance. This point is extremely important:

The Spaceport Trench Tower Key also opens the South Trench Tower.
If you accidentally use the key on the wrong tower, it will still be consumed.

Before unlocking anything, confirm that:

You are at the northernmost trench tower, not the southern one.

The map marker aligns with your position.

You see the right POI name and surroundings.

Only once you're sure should you proceed.

Unlocking the Entrance

There are two staircases, one on each side of the building. Choose either one and interact with the locked door using your key. After unlocking it, you'll enter the lower room of the tower interior.

Uploading the Blackmail Files

After entering the tower, the final steps to complete the quest are simple:

Head up the stairs immediately after entering (the staircase is to the left or right, depending on which door you used).

In the upper room, look for a glowing yellow terminal.

Interact with the terminal to upload the blackmail files.

Once the upload completes, the Turnabout quest is officially finished.

The process takes only a few seconds, but make sure the room is clear first-this location is a known choke point where raiders can easily catch players off guard.

Where to Extract After Completing Turnabout

After you've uploaded the files, you're free to extract from Spaceport. The region you're in offers a few extraction options, but one of the safest and most easily accessible is the Central Elevator, south of your current location. It provides good visibility and fewer vertical angles for ambushers to exploit.

However, before you leave the North Trench Tower:

Take Time to Loot the Area

The interior of the tower often contains valuable ARC Raiders Items, weapon cases, and crafting materials. Since you already spent the key, it's worth thoroughly searching the area before leaving.

Because each key grants a single tower access, many players revisit this POI whenever they find another Spaceport Trench Tower Key. The high loot density makes it well worth the return trip.

Tips for a Safe and Successful Turnabout Run

Bring solid mid-range weapons. The open trenches and sky-covering gantries invite long sightlines.

Avoid rushing directly to the tower. Scout the area first-raiders love waiting near the doors.

Carry smoke grenades. They help break the line of sight from Rocketeers and human snipers as you approach.

Secure your key in a protected slot. Losing it mid-mission forces you to restart the entire quest chain.

Consider approaching from the side. Flanking routes reduce the chance of ARC Raiders Coins for sale running straight into another raider's crosshairs.
