Locating specific mission objectives in the sprawling, multi-layered environments of ARC Raiders requires more than just a waypoint. One of the most common points of friction for Raiders early in their career is the "What We Left Behind" quest, specifically the segment requiring a search of Bilguun’s Hideout. This location is tucked away in the Spaceport district, a high-stakes zone where the verticality of the environment often works against players trying to track down small, makeshift structures.

The Context of the What We Left Behind Quest

The mission, assigned by the trader Tian Wen, serves as a comprehensive introduction to the diverse biomes of the post-apocalyptic landscape. It tasks players with retrieving data and items from three distinct maps: Buried City, Dam Battlegrounds, and Spaceport. While the first two locations are relatively intuitive for those who spend time exploring, Bilguun’s Hideout in Spaceport is notorious for its deceptive placement.

Understanding the lore and mechanics behind these hideouts helps in anticipating where they might be situated. In the world of ARC Raiders, scavengers like Bilguun utilize the existing infrastructure—walls, storage units, and industrial wreckage—to create temporary shelters that are difficult for both ARC machines and rival Raiders to spot from a distance.

Detailed Location of Bilguun’s Hideout

To find Bilguun’s Hideout, players must deploy into the Spaceport map. The hideout is not a standalone building but rather a modified field depot or container module attached to the massive boundary walls surrounding the Container Storage area.

Mapping the Coordinates

The primary landmark for this search is the Container Storage point of interest (POI), located roughly in the central-eastern portion of the Spaceport map. This area is dominated by a giant, collapsed ring structure and massive concrete overpasses. The hideout is specifically situated on the eastern wall that borders the storage yard.

Many players fail to find the objective because they focus on the ground level or the interior of the main storage buildings. However, the hideout is elevated. It appears as a yellow-painted metal structure clinging to the upper section of the wall. If you are standing in the center of the Container Storage yard looking east, you should be looking up at the interior face of the perimeter wall.

Environmental Cues

When approaching the area, look for signs of habitation that differ from the surrounding industrial decay. Bilguun’s Hideout is marked by scattered crates, makeshift lighting, and a distinct lack of ARC presence directly at the door, suggesting it was chosen for its relative obscurity.

Methods for Accessing the Hideout

Once the yellow container structure is identified, the challenge shifts to vertical traversal. Spaceport is a map that rewards players who understand the movement mechanics of the game, particularly mantle and jump distances.

The External Ladder Route

The most straightforward way to reach the hideout is via a metal ladder located on the side of a smaller container module attached to the main wall. This ladder leads directly to a narrow walkway that wraps around the side of the hideout.

  • Tactical Note: While the ladder is the fastest route, it leaves the player completely exposed. Climbing animations in ARC Raiders prevent the use of weapons, making you a stationary target for anyone perched on the nearby warehouse rooftops.

The Debris Climbing Route

For a stealthier approach, players can utilize the broken sections of the wall located slightly to the south of the hideout. Over time, the structural integrity of the Spaceport walls has failed, creating heaps of concrete debris and twisted rebar.

  1. Locate the section where the wall has partially collapsed into a ramp-like shape.
  2. Use a combination of sprinting and mantling to scale these blocks.
  3. Once atop the wall’s ledge, move north toward the yellow structure.

This route offers significantly better cover, as you can stay low and use the jagged concrete to break line-of-sight from the snipers that frequently inhabit the Container Storage rooftops.

Navigating the Dangers of Container Storage

Spaceport is widely considered one of the more dangerous zones for solo players or under-geared squads. The Container Storage area, in particular, is a natural funnel for player activity.

The Sniper Threat

The rooftops of the storage buildings provide long, unobstructed sightlines over the entire eastern wall. Experienced players often camp these positions to intercept Raiders attempting to complete the "What We Left Behind" quest. When moving toward Bilguun’s Hideout, it is generally safer to hug the base of the eastern wall. This puts you in the "dead zone" where snipers on the buildings cannot see you without leaning precariously over the edge.

ARC Patrols

While human players are the primary threat, the mechanical ARC patrols in Spaceport should not be underestimated. Small scout units frequently move through the alleyways between the containers. Engaging these units is often a mistake, as the noise will draw the attention of nearby Raiders. Using distraction tools or simply waiting for the patrol to move behind a container is the preferred method for reaching the hideout undetected.

Completing the Objective Inside the Hideout

Upon entering the hideout, do not expect a treasure trove of high-tier loot. The purpose of this location is narrative and quest-driven.

Finding the Scattered Notes

The specific item required for the quest is a collection of scattered notes. These are typically found on the floor near a makeshift table or a trolley inside the container. Interacting with these notes will trigger a quest update.

Secondary Loot

While the notes are the main goal, there are usually a few minor loot containers within the hideout. These often contain basic crafting components or low-value salvage. Given the high-risk nature of the location, it is usually advisable to grab the notes and prepare for immediate extraction rather than lingering to search every corner.

The Broader "What We Left Behind" Questline

To provide a comprehensive understanding of the task, it is essential to look at the other two objectives that often precede or follow the visit to Bilguun’s Hideout.

Buried City: The Parking Garage Raider Camp

This segment takes players to the Buried City, specifically the area between the Hospital and the Space Travel buildings. The objective is located beneath a parking garage. Players must find a breachable door on the elevator shaft and use a zipline to descend into a subterranean raider camp.

Inside this camp, you must search two specific containers. This location is actually a hidden gem for loot, often containing weapon crates that are overlooked by players who stick to the surface level. If you are completing this part of the quest, it is worth bringing a breach charge to ensure entry.

Dam Battlegrounds: South Swamp Outpost

The third objective is located in the South Swamp area of the Dam Battlegrounds map. Compared to Spaceport, this is a more open and horizontal engagement zone. The South Swamp Outpost is a small structure made of corrugated metal, often resembling a dilapidated tower.

Inside, players need to find a yellow-glowing item, usually books or logs, to complete the objective. The challenge here is the lack of cover in the swamp itself; moving through the water slows your movement speed significantly, making you vulnerable to ARC drones.

Gear and Reward Analysis

Completing the quest by visiting all three locations and returning to Tian Wen provides rewards that significantly impact early-to-mid-game weapon performance.

The Reward Package

Players typically receive the following weapon attachments:

  • Muzzle Brake II: Provides a significant reduction in vertical recoil, essential for high-fire-rate assault rifles.
  • Vertical Grip II: Improves ADS (Aim Down Sights) speed and further stabilizes the weapon during sustained fire.
  • Stable Stock II: Reduces weapon sway, which is particularly useful for players utilizing semi-auto rifles or marksman setups.

In the 2026 meta of ARC Raiders, these Tier II attachments are the baseline for viable PvP encounters. Without them, the recoil patterns of standard-issue weapons can be difficult to manage during the chaotic, fast-paced skirmishes found in the Spaceport district.

Tactical Extraction Strategy

Securing the notes from Bilguun’s Hideout is only half the battle. In ARC Raiders, quest progress is often tied to a successful extraction. If you die before leaving the map, you may have to repeat the objective depending on the current seasonal ruleset.

Choosing the Right Extract

For the Spaceport hideout, there are usually two viable extraction points. One is often located to the far east, past the collapsed ring, and another may be situated in the central plaza.

  • The East Extract: Usually safer but requires a long trek through open terrain where ARC units are more concentrated.
  • The Central Extract: Closer to the Container Storage, but significantly more likely to be contested by other squads looking to extract with their own loot.

Using Utility Items

When leaving Bilguun’s Hideout, using a smoke grenade at the base of the ladder can provide the necessary concealment to move away from the wall without being picked off by snipers. Additionally, saving your stamina for the final sprint to the extraction zone is crucial. Avoid jumping unnecessarily, as it depletes the stamina bar you will need to evade enemy fire.

Final Recommendations for the Search

If you find yourself unable to locate the hideout despite being at the Container Storage POI, check your verticality. The most common mistake is searching the ground level. Look for the yellow metal structure attached to the wall.

For solo players, attempting this quest during a heavy mechanical surge can actually be beneficial. When the ARC presence is high, many player-snipers vacate their rooftop positions to avoid being swarmed by drones, providing a window of opportunity to slip in and grab the notes.

Ultimately, Bilguun’s Hideout represents the core gameplay loop of ARC Raiders: environmental navigation, risk assessment, and the constant tension between the objective and the threat of other players. By prioritizing cover and understanding the layout of the Container Storage wall, you can navigate this "confusing" objective with minimal friction.
