Locating the Major’s Footlocker is a pivotal milestone for any Raider looking to bolster their anti-ARC arsenal in the Dam Battlegrounds. This mission, assigned by the NPC Tian Wen in Speranza, is more than a simple fetch quest; it is a deep dive into the history of the resistance and the key to obtaining the Hull Cracker, one of the most effective explosive weapons for dismantling heavy mechanical threats. While the objective seems straightforward—retrieve Major Aiva’s mementos—the execution requires navigating one of the most contested urban zones on the map.

Understanding the Quest Objectives

Tian Wen seeks closure regarding Major Aiva, a legendary figure in the early days of the defense against the ARC. The mission requires you to infiltrate the residential blocks near the dam to recover personal belongings left behind during the initial collapse. These items are stored in a specific footlocker hidden within an apartment complex known as the Ruby Residence.

Completing this task rewards you with the Hull Cracker blueprint. In the current meta of 2026, the Hull Cracker remains a top-tier choice for squad-based incursions, particularly when facing high-armor targets like Leapers or the formidable ARC Queen. The weapon’s ability to bypass significant portions of mechanical plating makes this quest a high-priority endeavor for both new players and seasoned veterans.

Preparing for Deployment to the Dam Battlegrounds

Before launching into the Dam Battlegrounds, your loadout choice is critical. The Ruby Residence is located in a high-traffic area that frequently attracts both high-level ARC units and opportunistic rival Raiders.

The Importance of the Safe Pocket

When attempting the Major’s Footlocker quest, avoid using a "Free Loadout." Instead, equip a standard kit that grants access to your Safe Pocket. The quest item, "Major Aiva’s Mementos," must be extracted successfully to complete the mission. By placing the mementos in your Safe Pocket immediately upon retrieval, you ensure that even if you are neutralized by a sniper or a sudden ARC swarm, the item remains in your inventory. This prevents the frustration of having to re-run the interior clearing process multiple times.

Recommended Gear

  • Weaponry: Close-quarters combat (CQC) is inevitable inside the apartment hallways. A reliable submachine gun or a rapid-fire shotgun is recommended for clearing interior rooms. For the exterior approach, a mid-range assault rifle with a suppressor can help you pick off Ticks and Raiders without alerting the entire neighborhood.
  • Gadgets: Bring scan grenades or motion sensors. The Ruby Residence is notorious for campers hiding in dark corners or behind kitchen counters.
  • Inventory Space: Ensure you have at least one open slot in your backpack. Although you intend to use the Safe Pocket, the initial interaction requires enough room to "pick up" the item from the container.

Navigating to the Ruby Residence

The Ruby Residence is a cluster of multi-story apartment buildings situated in the northwestern sector of the Dam Battlegrounds map. It is located to the west of the Generator Halls and north of the Hydroponic Dome.

The buildings are easily identifiable by their distinct reddish-brown brickwork, which stands out against the metallic and concrete ruins of the surrounding infrastructure. The complex consists of three main structures. Your target is the southwestern building—if you are looking at the map, it is the leftmost of the two lower buildings in the cluster.

Be aware that the approach to Ruby Residence is often patrolled by ARC Rocketeers. These units can deal massive splash damage from the rooftops of nearby utility sheds. It is often safer to approach from the western forest line, using the natural terrain as cover until you reach the ground-floor entrances of the apartments.

Step-by-Step Guide to the Footlocker Location

Once you have entered the correct building (the southwestern block), the challenge shifts from long-range navigation to tactical room clearing.

Clearing the Ground Floor and Stairwells

Do not sprint blindly up the stairs. The stairwells in the Ruby Residence are common spawn points for ARC Ticks—small, explosive mechanical units that can end a run in seconds. Listen for the telltale metallic clicking sound. Use your melee attack to dispatch them quietly if they are isolated, or a single suppressed shot if they are grouped.

Reaching the Target Floor

You need to ascend to the highest habitable floor of the building. Note that this is not the rooftop itself, but the floor immediately beneath it. On the map and in-game UI, this is generally referred to as the third floor (or second floor depending on whether the lobby is counted as zero).

Locating the Specific Apartment

Once on the top floor, move down the hallway toward the end of the building. You are looking for a suite-style apartment that features a large living area with windows overlooking the dam.

  1. Enter the Suite: Walk through the living room and bypass the small kitchenette.
  2. The Back Bedroom: Move into the room located directly behind the kitchen area. This is the bedroom where Major Aiva spent her final nights before the evacuation.
  3. The Desk: Near the window, you will see a wooden desk. Resting on top of this desk is the Major’s Footlocker—a small, yellow-tinted container.

Interacting with the Mementos

A common issue reported by Raiders is the interaction prompt failing to appear when standing in front of the desk. The geometry of the room can sometimes interfere with the "Search" command. If the prompt does not appear:

  • Crouch and look directly at the center of the box.
  • If that fails, hop onto the desk and stand directly over the footlocker. This usually forces the game to recognize the proximity and allows you to retrieve "Major Aiva’s Mementos."

Once the item is in your inventory, open your menu immediately and move it into your Safe Pocket.

Survival and Extraction Strategies

Retrieving the mementos is only half the battle. You still need to leave the Dam Battlegrounds to deliver the items to Tian Wen.

High-Risk Zones

The area surrounding the Ruby Residence is a "hot zone." Many players farm this location for high-tier loot and the Blue Gate Cellar Key, which frequently spawns in nearby rooms. Expect contact with other players. If you hear gunfire nearby, it is often better to wait in the apartment for a few minutes until the engagement moves elsewhere.

Choosing an Extraction Point

  • The Swamp Lift: This is often the safest bet for players finishing the Footlocker quest. It is located to the south and provides a relatively obscured path through the wetlands. While Rocketeers sometimes guard the perimeter, the lift itself offers good line-of-sight protection.
  • The Dam Elevator: Avoid this if possible. It is a notorious camping spot for snipers and is often overrun by heavy ARC units.
  • Emergency Extraction: If you have an extraction flare, the park area just outside the Ruby Residence is an option, but be warned: the flare will act as a beacon for every Raider in the sector.

The Reward: Analyzing the Hull Cracker

Returning to Speranza and handing the mementos to Tian Wen unlocks the Hull Cracker blueprint. This weapon is widely considered a "must-have" for any serious ARC-hunting squad.

Weapon Performance

The Hull Cracker is an explosive-based projectile weapon. Unlike standard rifles that rely on kinetic impact, the Hull Cracker utilizes shaped-charge rounds designed to penetrate the thickest carapaces of the ARC units.

  • Anti-Armor Specialist: It excels at stripping the protective plates off Leapers, making them vulnerable to follow-up fire from teammates using standard ballistics.
  • Area of Effect: While the primary focus is penetration, the slight splash damage is excellent for clearing clusters of Ticks or suppressing Raiders behind thin cover.
  • Downsides: The reload time is significant, and the projectile travel speed requires you to lead your shots at long distances.

Crafting the Hull Cracker

Once the blueprint is unlocked, you will need to visit the Gunsmith. Note that your Gunsmith station must be upgraded to Level 3 to craft this weapon. The material requirements are:

  1. Magnetic Accelerator (1): These are rare drops found primarily in high-security zones like the Research & Administration building or the Dam Control Tower. Look for crates labeled "High-Value Electronics."
  2. Exodus Module (1): A rare component often found in the wreckage of larger ARC units or within the secret rooms of the Spaceport. You may need to use a keycard to access the areas where these are most common.
  3. Heavy Gun Parts (3): These can be acquired by dismantling rare or epic-tier weapons that you extract from the battlefield. They are also occasionally found in industrial toolboxes scattered throughout the Stella Montis zones.

Tactical Summary for Success

To ensure a successful run for the Major’s Footlocker, remember the following principles:

  • Silence is Life: Use suppressed weapons whenever possible to avoid drawing the attention of both AI and players.
  • Horizontal and Vertical Awareness: ARC units in the Dam Battlegrounds love to flank from above or beneath the floorboards. Always check the ceilings for Ticks.
  • Patience at the Desk: Don't panic if the interaction prompt is finicky. Jump on the table, adjust your angle, and ensure your inventory isn't full.
  • Safe Pocket is Mandatory: Never carry quest-critical items in your main backpack unless your Safe Pocket is already occupied by something even more valuable (which is rare for this stage of the game).

The quest for the Major’s Footlocker is a test of a Raider’s ability to navigate tight spaces and manage risks. By following this guide, you can efficiently secure Major Aiva’s legacy and equip yourself with the firepower needed to take on the most dangerous threats the ARC has to offer. Whether you are playing solo or in a coordinated squad, the Hull Cracker will significantly change how you approach combat encounters in the future.
