How to Complete the Last Entry Quest in ARC Raiders
What makes Last Entry challenging is not navigation across multiple zones, but the fact that all objectives must be completed in one continuous attempt, including extraction with the final quest item. If you die before extracting, you lose progress entirely and must restart the quest chain.
This walkthrough breaks down every step clearly, including optimal routing, item interactions, and survival tips to ensure a smooth completion.
Preparing for the Mission
Before entering Stella Montis, preparation is more important than most players initially assume. While Last Entry does not require a high-end build, it does demand efficiency and survivability because mistakes are costly.
The environment inside and around the Seed Vault is dense with ARC patrols, environmental hazards, and narrow corridors that limit escape options. As a result, your loadout should prioritize:
A balanced weapon suited for both mid-range and close-quarters engagements
Enough ammunition to handle multiple ARC encounters without resupply
Healing items to recover from chip damage sustained during traversal
A mobility-focused augment if available, since repositioning is often more important than raw defense
It is also highly recommended to reserve at least one secure inventory slot if your gear allows it. The final quest item must be extracted, and losing it on death resets your progress entirely. You can buy ARCR Items to get them.
Step 1: Reaching the Seed Vault Area
Your first objective begins outside the Seed Vault, located in the southeastern section of Stella Montis. The approach typically involves navigating through industrial tunnels, broken maintenance corridors, or partially collapsed entryways depending on your spawn point.
As you approach the Vault zone, you will notice a shift in environmental design. Lighting becomes harsher, structural integrity appears compromised, and ARC presence increases. This area often serves as a contested space, meaning you should expect both NPC threats and potential player encounters.
Instead of rushing directly into the Vault entrance, your priority is to locate a nearby workstation positioned just outside or slightly above the main entrance structure. This terminal acts as the initial quest trigger.
Interacting with this workstation will:
Register the first quest objective completion
Trigger a researcher log interaction that provides narrative context
Confirm that you are on the correct progression path
A common mistake is skipping this step and immediately entering the Vault interior. Doing so may cause confusion later in the quest chain, as subsequent interactions depend on this activation.
Step 2: Recovering the Seed Vault Key
After activating the workstation, your next destination is a small adjacent room located near the entrance zone. This room is easy to overlook because it blends into the surrounding industrial architecture.
Inside, you will typically find medical or containment-related props, including a rack of orange hazmat suits. This is not just environmental decoration-it is a scripted interaction point.
Approach the suit rack and interact with it. Once triggered, a key item will drop onto the floor:
The Seed Vault Box Key
This key is essential for progressing further into the quest. Without it, you will be unable to access the internal Seed Vault systems later.
After picking up the key, take a moment to scan the room for additional supplies. Fuel cells or minor loot spawns can occasionally appear here, and grabbing them early can reduce backtracking later in the mission.
Once the key is secured, you are ready to move toward the Vault proper.
Step 3: Powering the Seed Vault Entrance
The Seed Vault is a sealed facility that requires external power activation before entry. This is where the quest begins to introduce light resource management.
To open the Vault, you will need a fuel cell. These are not fixed in one location, but instead spawn in nearby maintenance areas, tunnels, or side rooms surrounding Stella Montis.
Once you locate a fuel cell, return to the main Seed Vault entrance. You will find a power socket panel integrated into the sealed door system.
Insert the fuel cell into the panel. This initiates a short activation sequence during which the system powers up. After completion, the massive Vault door will unlock, granting access to the interior.
This moment is significant because it marks the transition from exterior traversal to high-density interior combat space.
Inside the Vault, ARC enemy encounters become more frequent, and visibility is often reduced due to industrial lighting and containment structures.
Step 4: Navigating the Interior and Locating the Terminal
Once inside the Seed Vault, your objective shifts toward deeper exploration. The interior is structured as interconnected containment zones filled with research pods, storage units, and monitoring stations.
Your target is a seed deposit terminal located deeper within the facility. It is typically found near large pod arrays or at the end of a side corridor branching from the main interior path.
The environment here can be disorienting due to repetitive structural design, so careful movement is important. Avoid rushing forward blindly, as ARC units often patrol junction points and can ambush players in tight corridors.
When you locate the terminal, approach it and interact. You will be prompted to use the Seed Vault Box Key obtained earlier.
Using the key unlocks a secure deposit interface and triggers the next major quest reward.
Step 5: Retrieving the Shutdown Documentation
After successfully unlocking the terminal, you will receive a critical quest item:
Official Shutdown Documentation
This item represents the core objective of the entire mission. It contains classified information tied to the Seed Vault's operational shutdown procedures and is required for quest completion.
At this point, your focus should shift immediately from exploration to survival. The moment the item enters your inventory, you are effectively in extraction phase.
The most important consideration here is risk management. Dying at any point after acquiring this document will force a full quest restart, regardless of how close you were to extraction.
If your build allows for secure storage, place the document in a protected inventory slot immediately.
Step 6: Extraction Strategy and Exit Route
With the Official Shutdown Documentation secured, your final objective is extraction.
The nearest extraction points are typically located within the surrounding tunnel network or along accessible exits near the Seed Vault perimeter. However, reaching them safely is often more difficult than obtaining the quest item itself.
At this stage, several threats must be considered:
ARC patrol units may spawn or rotate into your path
Other players may be camping extraction routes
Narrow corridors limit your ability to disengage safely
A successful extraction strategy relies on patience rather than speed. Moving cautiously, clearing corners before advancing, and avoiding unnecessary engagements will significantly improve your survival chances.
If you encounter resistance, disengagement is often the correct decision unless extraction is immediately blocked.
Once you reach an extraction zone, initiate the extraction process and remain alert until completion. Even during extraction, threats can still interrupt progress.
Final Completion and Quest Turn-In
After successfully extracting from Stella Montis with the Official Shutdown Documentation, the quest is considered complete. You will then return to the quest hub or relevant NPC to finalize progression and receive rewards.
These rewards typically include progression experience, ARC Raiders Items, narrative advancement, and potential access to follow-up missions tied to Seed Vault operations or ARC research activities.
Conclusion
The Last Entry quest in Arc Raiders is a compact but highly structured mission that tests situational awareness, resource management, and extraction discipline. While it does not require complex combat mechanics, it emphasizes careful sequencing and survival planning.
Once mastered, this quest also serves as a foundational introduction to the Seed Vault system and Stella Montis layout, both of which are central to more advanced missions later in the game.
