[Ark Raiders]Compatible with the latest update in 2025! A complete guide to the most efficient route for night raids, electromagnetic storms, and key room utilization to collect blueprints with a high probability.

ARC Raiders is a PvPvE cooperative survival shooter set on a collapsed Earth where players compete for resources with friends and rivals to survive. The best part of this game is crafting powerful weapons and gadgets to fight. The key to achieving this is the “blueprint”. The reality is that if you don't collect blueprints, you won't be able to upgrade even basic firearms, making it easy to struggle in the early stages. Especially since the latest update in 2025, the drop specifications for blueprints have changed and the difficulty of obtaining them has increased significantly. Even if you wander around the map haphazardly, you will rarely get high rare blueprints (epic or legendary).

This guide provides detailed explanations of the most efficient routes that make the most of night raids, electromagnetic storms, and key rooms, both for solo and parties. From beginners to advanced players, we will reveal strategies that allow you to stably obtain multiple blueprints in one raid. This content takes into account post-update adjustments (drop rate changes from Raider Containers, etc.). If you practice, you can efficiently collect popular blueprints such as Venator and Wolfpack. Read on and start enriching your Speranza workshops in no time.

There are over 74 types of blueprints, divided into weapons (Anvil, Venator, etc.), attachments (Extended Magazine, Muzzle Brake), Gadgets (Revival Device, Jolt Mine), etc. Use the damaged blueprints by selling or exchanging them. Exchange recruitment is active, and you can aim for rare items using Shotgun Choke II and medium-sized gun parts as bait.

1. Reasons for the change in the difficulty of obtaining blueprints (detailed explanation of blueprint specification changes)

Blueprint drop rates from Raider Containers have been adjusted in 2025 November Update 1.2.0 (North Line). As a result, the previous situation where high rares were found randomly through fishing has ended, and strategic laps are now required. Specifically, the lottery table for containers will become narrower, and low-rare drops from regular containers will increase. On the other hand, the expected value of high rares only increases under certain conditions (night attack, electromagnetic storm, key room).

Additionally, the 1.3.0 patch adjusted Venator's firepower and emphasized the importance of collecting blueprints. This is because without the Venator blueprint, you will be at a disadvantage in high difficulty ARC and PvP. Players have been reporting things like “I can't find blueprints for medium-sized guns'' and “Wolf packs finally appeared in night raids.'' This change is a balance adjustment aimed at making the game longer. If you ignore it, you won't even get enough trial rewards and your growth will stop after level 15.

The problem before the change was that the luck game element was too strong. After the update, you can increase the drop rate by more than 3 times with knowledge (understanding conditions) and route optimization. For example, the enemy/container lottery table during night raids will be expanded, and the probability of high rare will increase by 20-30%. In electromagnetic storms, snap hooks drop heavily. If you take advantage of this, you can stably obtain 5-10 blueprints in an hour. Beginners should first familiarize themselves with this specification.

2. Understand the basic specifications of blueprints (thorough explanation of how high rares appear)

Blueprints can be permanently acquired by “memorizing and consuming” them at Speranza's workshop. Select it from your inventory, consume it, and add it to the crafting menu. The overlap can be transferred to other players by selling it (turning it into gold) or dropping it. You can check the list of workshops to see if you have completed the training.

The mechanism for high rares is the “lottery table”. Usually containers (lockers, drawers) are centered around common blueprints (small gun parts, etc.). Weapon cases and key rooms are set to be rare or higher, and the expected epic value is high for defeating the Surveyor. With the update, the table has shifted to conditional dependence.

• Common (green): Basic parts (gun parts), easy to appear anywhere.
• Rare (blue): Attachments (silencer II, vertical grip III).
• Epic (purple): Weapon body (Venator, Wolfpack), Mk.3 armor.
• Legendary (gold): A rare gadget (revival device).

The expected values ​​by source are as follows.

source	Expected rarity	Estimated drop probability (after update)
regular container	Common-centered	Total blueprint 5%
weapon case	Rare or higher	Blueprint 30%, Epic 10%
key room	Epic focus	Blueprint 50%, multiple at the same time
surveyor	epic	Blueprint 20-40% + ARC material
trial reward	fixed rare	Guaranteed 1-2 items per week

Please prioritize based on this table. The trick is to use quests (such as trigger grenades in Sparks) and not rely solely on fishing.

3. Conditions to aim for blueprints most efficiently (detailed usage of night raids, storms, and key rooms)

There are three strongest conditions. The combination creates a synergistic effect.

Utilizing night raids

At night (recommended to start around 18:00), the enemy/container lottery table will expand. The probability of high rare blueprints will increase to more than twice the normal rate. The PvP risk increases due to poor visibility, but it also increases the chances of Surveyors appearing. There are also many reports of Venators appearing in the Blue Gate at night. For the start timing, after selecting the map, check the night conditions and descend immediately.

Utilization of electromagnetic storm

When a storm occurs, there is a high probability that snap hook or jolt mines will drop. The electronics go haywire and the ARC becomes weak. Container efficiency is greatly improved by prioritizing storm area movement. Storm frequency is stable in patches.

Utilization of key room

Inside the locked door (unlocked with 3 fuel cells) and the destroyed door is a high-rare exclusive table. There are many weapon cases and black boxes, including a puzzle room. Please be sure to bring your bleach charge. Be careful of the bug that allows you to sneak through the key room.

point: If you meet the triple conditions of night + storm + key room, you can get 3 blueprints in one room. It is important to understand the key collection route in advance.

4. By map: Featured areas where blueprints are likely to fall (Complete map explanation of Blueprint nest)

Buried City (Plaza Rosa/City)

There are 26 weapon cases + 2 key rooms. Areas where houses can be invaded through roof windows are particularly dense. There have been numerous reports of Venators in Santa Maria houses and solar panel breakthrough routes. There are also plenty of safe routes for beginners.

Recommended spots

1. Houses on the east side of the village: Trash cans and lockers are crowded together.
2. Office building: Parts blueprints often come out of drawers.
3. Key room (red pin): Multiple weapon cases are located here.

Blue Gate

The underground “reinforced reception'' bleach room is the strongest. We recommend going around the red area. You can aim for materials and blueprints at the same time even around checkpoint vehicles. Although it is a fierce battleground, the appearance rate of Epic Mk.3 during night attacks is very high.

Route example: Enter through the three entrances, perform bleaching, and search the locker room. The expected value of gold 30,000 + blueprint is high.

Stella Montis

The black boxes are densely packed. This is a new map (added in 1.2.0) and is highly dangerous, but the reward is also great.

In addition, the Dam Battlefield (yellow area for beginners) and Spaceport (Launch Building Locker) are also effective.

map	Featured area	Expected number of blueprints/raid	Difficulty level
buried city	houses/offices	4-6	Medium
blue gate	enhanced reception	5-8	high
Stella Monteith	black box	6-10	high

5. Drop tendency for each type of container (optimization of aiming method for each container)

• Trash can/recycle box: Parts blueprints (small/medium gun parts) have a high probability. Recovery is possible with low risk.
• Black box: Epic weapon (such as the Wolf Pack).
• Lockers, shelves, drawers: Common to rare attachments. Priority will be given to office buildings.
• Weapon case (large green): Rare weapon itself. Common on rooftops and military facilities.
• Raider treasure chest: Discovered by the buried sound “chitchitchi”. It exists in the bleach room.
• Puzzle room: Unlock with 3 fuel cells. Definitely high rare.

container	main drop	priority
trash can	parts	high
black box	epic weapons	top priority
weapon case	weapon blueprint	top priority

6. Importance of Surveyor (mini-boss-level defeat strategy)

If you defeat the ARC reconnaissance plane (black ball rolling type), you will get 20-40% blueprint + materials. The appearance rate is high at night. You can safely defeat it with a wooden hook. Since they can run away quickly, it is effective to use a shotgun.

Defeat procedure

1. Once you find it, hide behind the object.
2. Guide the enemy closer and fire a series of headshots.
3. Make sure to collect the drops.

7. Most efficient blueprint route (strategy summary for actual battles/by solo/PT)

Solo night attack Blue Gate route (5 blueprints expected in 30 minutes)

1. Descent: Entrance to reinforced reception.
2. Execute Bleach 1 and search for lockers (about 2 parts).
3. Enter the key room (collect fuel) and collect the black box/weapon case (expected to be 2 epics).
4. Surveyor hunt.
5. I will return.

Party Electromagnetic Storm Buried City Route

1. Everyone gathers in the houses area.
2. Perform a dormer entry and clear all containers.
3. Execute storm standby and aim with snap hook.
4. Works with the spaceport.

The left locker in the spaceport launch building requires a door stopper. Always be alert in PvP and move quietly.

8. Additional Tips: Quest/Trial/Exchange Utilization

You can obtain the trigger grenade from the quest “Sparks Fly”. For the trial, you will receive a blueprint as a weekly reward for level 15. In exchange, if you sell part blueprints, you can trade them for rare blueprints.

Summary: Collecting blueprints after the latest update is all about “knowledge x route”

Please orbit around the Buried City and Blue Gate, focusing on night raids, electromagnetic storms, and key rooms. Scavenge all the containers and make sure to defeat the surveyor. This alone will dramatically improve the efficiency of collecting blueprints. Implement this strategy and your Speranza workshop will become the strongest in no time. Gather powerful equipment and aim for even greater heights.
