ARC Raiders is a PvPvE extraction shooter developed by Embark Studios and distributed by Nexon. It is a survival adventure game set in the underground world of Speranza on the collapsed Earth, where you collect resources to survive and fight against rival players and the mechanical life form ARC, which has attracted many players. The expedition system is positioned as the end content of this game. Expeditions are an optional reset mechanism that resets a player's progress in exchange for permanent powerful buffs and special rewards, and runs on a cycle approximately every 8 weeks.

In order for your expedition to be successful, you will need to deliver large amounts of resources in five preparatory steps, starting after reaching level 20. The preparation period is approximately 53 days, and the expedition can only be carried out during the final 7-day departure period. Executing expeditions accumulates benefits such as storage expansion and bonus skill points, making it an essential system for long-term players. Casuals, on the other hand, can skip and take over the progression. This article provides a comprehensive explanation of the entire expedition, from beginners to experts, and supports efficient preparation.

Expedition release conditions and overall schedule

Expedition Projects are unlocked at player level 20. To level up, it is effective to earn experience points by exploring the field, clearing quests, and strengthening the workshop. Start by selecting an expedition project from the project menu. The schedule is as follows, and each cycle is approximately 60 days.

  • Preparation steps 1 to 5: Each step will be unlocked in sequence and resources will be delivered. Final preparations will be completed when all steps are cleared.
  • Departure period: Expeditions can only be carried out for the final 7 days. Only delivered players can participate.
  • After completing the expedition: An immediate reset will occur and buffs will be applied. The next cycle will begin.

List of resources required for all 5 steps of the expedition and detailed explanation

Expedition preparation consists of 5 steps, and specified resources will be delivered for each step. Resources can be obtained through field exploration, collecting Scrappy chickens, and workshop production. The complete list is summarized in a table below, and the rarity of each item and recommended acquisition method are listed.

Step 1: Basics (1/6)

This is an introductory step focusing on basic materials. You can collect them efficiently on the early map.

resource name Required number rarity Main locations/methods of acquisition
metal parts 150 common Collecting scrappies and box fishing on low level maps.
rubber parts 200 common Scrappy collection, exploring around tires and trash cans
ARC alloy 80 uncommon Aim for machine debris and ARC destruction drops on mid-level maps.
steel spring 15 rare Check boxes in vehicle wrecks and factory areas

The total number will be approximately 445 pieces. If you sortie 10 times a day, you can clear it within a week. Sign up for resource tracking to make it easier to find.

Step 2: Core system (2/6)

Electrical materials are increasing, and cooling fans are key. Obtaining fans can easily become a bottleneck.

resource name Required number rarity Main locations/methods of acquisition
durable clothes 35 uncommon Obtained from clothing boxes in camping and residential areas, and by defeating ARC.
wire 30 common Explore electronic equipment and switchboards
electrical parts 30 common Search for home appliances and collect them with Scrappy assistance.
cooling fan 5 rare We will focus on server rooms and PC debris on medium to high level maps.

Since cooling fans are rare, they can be produced at Utility Station Lv3. Prioritize pre-fortification.

Step 3: Framework (3/6)

Sensors and Exodus modules will be a challenge. Epic items will appear for the first time.

resource name Required number rarity Main locations/methods of acquisition
light bulb 5 uncommon Lighting equipment, obtained in the office area
battery 30 uncommon Perform vehicle/device search
sensor 20 rare Surveillance cameras aim at drone debris. High level maps recommended
exodus module 1 epic Boss ARC (Exodus type) drop, aim for rare search

The Exodus module has a strong luck element. We recommend aiming with multiple accounts or team play.

Step 4: Equipment (4/6)

The focus will be on advanced materials. Reaper pulse is near the end.

resource name Required number rarity Main locations/methods of acquisition
humidifier 5 rare Check shelves in medical facilities/lab areas
advanced electrical components 5 rare High-level electronic equipment development and gunsmith production
magnetic accelerator 3 epic Aim at accelerator facilities and special event maps
Reaper pulse unit 3 epic Reaper ARC boss drop, go around the spacecraft storage

These rare epics require storage expansion. Please keep it as a priority instead of selling it.

Step 5: Loading stage (5/6)

Based on coin conversion value. Accumulate a large amount of items by category.

category Required value (coins) example item
combat items 250,000 weapons, parts and ammunition
survival equipment 100,000 medical kits, tools
food 180,000 ingredients, drinks
material 300,000 parts, alloys, etc.

The total value is 830,000 coins. Collect low value items in large quantities or accumulate high value rares without selling them. Collect battle items at the risk of losing your weapon.

Although the total amount of resources is huge, we are able to proceed in a planned manner as the deliveries will be distributed over 8 weeks.

Efficient methods of obtaining each resource and farming routes

When collecting resources, the golden rule is to use the resource tracking function. If you register in the workshop menu, an eye icon will be added to make it easier to identify when searching. If you strengthen Scrappy to Lv5, the basic materials will increase dramatically.

Obtaining large amounts of common materials

Traverse lower level maps with free loadouts. The basics are box fishing and collecting scrappie. You can get hundreds of them in 5-10 minutes per match by following the route of Spaceport Area → Ruins Camp → Immediately Returning to the Elevator. Be careful not to exceed the weight. Increase capacity by rolling the skill "Broad Shoulders".

Uncommon to rare materials

Focus on specific points on the mid-level map. Aim for the cooling fan in the server room, and the humidifier in the medical lab. It is efficient to distribute vigilance among teams. Targeting and defeating ARC weak points will increase the drop rate.

epic material

The main focus is boss hunting on high-level maps and hidden storage events. The rare drop rate will increase under night attack map Blue Gate and electromagnetic storm conditions. Workshop production after obtaining the blueprints is also effective.

For step 5, all categories are combined and accumulated. It is essential to expand your storage to its maximum capacity.

Reset contents after an expedition: complete list of what is lost and what remains

Expeditions are optional, but it is important to understand the disadvantages.

what to lose

Player level & skill points, full amount of coins, inventory & storage items (excluding deliveries), all types of blueprints, workshop level progression (unlocked stations are maintained), quest progress, raider hideout, storage upgrade progress (compensated with buffs)

What remains

Unlocked maps, workshop station unlocks, codex items, raider tokens & credentials, rankings & trial progression, decorative items (skins, emotes), personal event progression, all past expedition buffs (stacking)

Immediately after reset, rebuild with free loadout. Re-obtaining blueprints is a pain, but buffs will speed it up.

Expedition rewards and permanent buff details

The biggest attraction is the stackable buffs (there is a limit). Powerful from the beginning.

Buff name effect Acquisition conditions
Additional storage slot Number of slots increases Clear all steps
bonus skill points Up to 5P will be added Step 5 Increase value
Increased amount of XP gained Improves search efficiency consecutive expeditions
Scrappy material increased Basic resources will increase dramatically Achieved Lv5 immediately
Increased number of weapon repairs Improves durability Expensive weapon use

You can also get special decoration rewards (limited skins). You can complete the skill tree by running it multiple times.

Should we go on an expedition? Judgment by recommended play style

Be sure to carry out your long-term commitment. You can overwhelm other players by stacking buffs. Intermediate daily students may skip the first time, but it is recommended from the second time onwards. Casual players who play once or twice a week are recommended to skip it. You can enjoy it by maintaining progress. If you are solo, it will be easier to optimize the route, and if you are in a team, it will be easier to share.

The advantages far outweigh the disadvantages, so it is a must-have system if you want to continue using it.

Essential tips for early to mid-season preparation for expeditions

  1. Improve operability by turning off visibility distortion and adjusting aim sensitivity.
  2. The sortie flow is tracking registration → low cost loadout → escape pin → rare priority fishing → immediate return.
  3. By using the safety pocket, you can bring back rare items even when you surrender.
  4. To strengthen Scrappy, aim for Lv5 with dog collar → fruit → ingredients.
  5. Prioritize quests and get rares from Celeste trading.
  6. To avoid PvP, repeat the emote "Don't shoot".
  7. Earn coins and expand your storage by selling free augments.

This will more than triple the preparation efficiency.

Multiple expedition strategy: Buff maximization loop

From the second time onwards, a buff will speed up resource collection. You can rebuild the optimal build by resetting your skills. The goal is to reach the maximum buff limit in 5 expeditions.
