Spent countless raids hunting ARC Raiders BluePrints without success? I did too, and even considered whether it was worth trying to buy ARC Raiders BluePrints (https://www.mmoexp.com/Arc-raiders/Items.html?fsid=851495) . After testing different containers, events, and maps, I found several farming methods that consistently delivered better results.
1. Stop Looting Everything — Some Containers Are Better
While every container in ARC Raiders can potentially drop a blueprint, some loot sources seem to offer much better odds.
The containers I prioritize every raid are:
* Weapon Cases
* Ammo Crates
* Med Crates
* Utility Crates
* Raider Caches
* Security Lockers
These consistently provide access to some of the best blueprint loot pools in the game.
2. The Best Sources for Weapon BluePrints
If your goal is unlocking stronger weapons, focus on these locations first.
2.1 Metal Ammo Boxes:
Many players report finding weapon blueprints such as the Anvil and Osprey from these containers.
2.2 Weapon Cases：
Weapon Cases are among the most valuable containers in the game, often rewarding weapon and attachment blueprints.
2.3 Raider Caches：
Whenever you hear the familiar ticking sound, make it a priority. Raider Caches are widely considered one of the most rewarding blueprint sources available.
3. The Most Underrated Loot Spot
Red Lockers deserve far more attention than they receive.
Unlike containers that specialize in certain blueprint types, Red Lockers seem to pull from a huge variety of rewards, including weapon, attachment, and utility blueprints. Some of my most valuable blueprint finds have come from these overlooked containers.
4. Night Raids Are a Blueprint Goldmine
One of the biggest mistakes players make is farming only during daytime raids.
Night maps increase high-rarity loot chances by up to **150%**, making them one of the best ways to improve your chances of finding rare ARC Raiders BluePrints. The extra danger is usually worth the reward.
5. Don't Miss These Hidden Blueprint Sources
Blueprints don't only come from containers.
Surveyor：
The large rolling Surveyor robot has a surprisingly good blueprint drop rate. If you spot one, take it down.
Trials：
Unlocked at Level 15, Trials can reward multiple loot packages for completing three-star objectives. Over time, they become one of the most reliable sources of extra blueprints.
6. Bonus Tip
If you find duplicate blueprints, don't rush to get rid of them. Many players use duplicates for trading, while others supplement their progression by checking available ARC Raiders Items for sale (https://www.mmoexp.com/Arc-raiders/Items.html?fsid=851495) and focusing their in-game time on farming rarer blueprints instead.
7. Final Thoughts
Focus on high-value containers, Night Raids, Trials, and Harvester Events. These methods helped me collect ARC Raiders BluePrints far faster than random looting ever did.
