When players first saw ARC Raiders Expedition 4 challenge requiring them to accumulate 100,000 damage, many initially thought it would be an extremely time-consuming and even insurmountable challenge.
However, according to EZG's actual testing, this task isn't as difficult as it seems. While the number appears staggering, with the right approach during normal gameplay, you can quickly accumulate progress.

This guide will detail how to complete ARC Raiders Expedition 4 Damage Challenge and the specific rules of the new Catch Up mechanism to help you complete it faster.
Task Requirements
In ARC Raiders Expedition 4, whether it's your first time participating or you've completed multiple Expeditions, you need to complete Damage Challenge before July 21st to progress.
The goal of this challenge is very simple: accumulate 100,000 damage against destructible targets in ARC Raiders. This damage includes not only ARC machines but also Raider player characters and other attackable targets.
Many players initially misunderstood this quest; successful extraction isn't required to gain damage progress. If you defeat an ARC enemy in a raid, the damage dealt is recorded and won't disappear even if your character dies or doesn't finish them off.
EZG testing revealed that playing ARC Raiders for a few hours normally easily yields over 30K damage progress. Even without specifically grinding the quest, progress is rapid simply by completing Trials, exploring the map, and gathering resources.
ARC Objectives
The difference in damage progress provided by different ARC Raider units is significant. Smaller ARCs, such as Ticks and Pops, offer very little progress, requiring many kills to complete the quest.
In contrast, killing medium to large ARCs is significantly more efficient. Bombardiers provide approximately 2,600 to 2,700 damage, Leapers around 1,100 damage, while large boss-level ARCs like Queen and Matriarch can provide close to 10,000 damage in a single hit.
Therefore, if your goal is to quickly complete ARC Raiders 100K challenge, you should prioritize targeting large ARCs rather than spending a lot of time killing low-level units.
It's worth noting that the official ARC Raiders website mentioned that a Bastion provides 5000 progress points, leading many players to believe that completing 100K challenge requires killing 20 Bastions. However, based on testing, EZG observed that the actual progress gained isn't that high.
In ARC Raiders, a Bastion actually provides only about 2,600 Damage Challenge progress points, not 5,000. The 5,000 point figure is more likely related to the experience reward after the kill, rather than damage calculation within the challenge.
This may be related to the armor mechanics of ARC Raiders. Bastions and some high-level ARCs possess black armor, which is very difficult to break, requiring a large amount of ammunition to defeat, and the damage dealt doesn't fully convert into Damage Challenge progress.
Conversely, some ARCs with thinner armor, such as Bombardier or Vaporizer, while seemingly easier to kill, have a higher damage conversion rate. Therefore, when facing 100K Damage Challenge, higher health enemies aren't necessarily more worthwhile to farm.
Recommended Method
Choosing high-damage ARC Raiders Items is key to maximizing efficiency. Jupiter, Hullcracker, Deadline, and Wolfpack are all highly recommended. Among these, Jupiter is particularly suitable for farming ARC damage.
It boasts excellent long-range damage output, allowing players to attack ARC targets while maintaining a safe distance and quickly accumulate challenge progress. For large ARC battles like Queen or Matriarch Events, it's advisable to prepare ample ammunition beforehand and maintain continuous damage output to maximize the damage gain from each event.
Currently, Harvester Event and Matriarch Event are highly efficient areas for completing Damage Challenge, helping you find high-health targets and accumulate damage more quickly. However, it's important to note that these locations are very popular, and multiple players may attack the same boss simultaneously. Therefore, don't rely on achieving high damage output in every run.
Adjusting your route flexibly based on the actual situation and restarting the raid if necessary will actually maintain a more consistent completion rate.
Reward Changes
The reward mechanism is different this time. Previously, Expedition primarily rewarded Skill Points, but Expedition 4 no longer provides new Skill Points. Instead, it rewards Stash Expansions, Raider Tokens, and random blueprints.
Completing multiple stages of Damage Challenge will earn your Raider Tokens and a chance to obtain random Blueprints from the official reward list. These blueprints are very valuable for subsequent expeditions, as they may grant you powerful gear at the start of expedition.
However, this also introduces an additional problem: if a player already possesses an ARC Raiders Blueprint saved in Expedition Vault, the random rewards may overlap with it, leading some players to believe that the new system conflicts with Vault mechanism.
Catch Up Guide
ARC Raiders has added a Catch Up mechanism for players who missed some Expeditions, but it's not available to all players. Only players who meet specific conditions can recover previously missed rewards.
If you completed Caravan of a previous Expedition but didn't complete the final challenge stage, such as Coin Mission or Damage Challenge, you'll have a chance to recover missing Skill Points through Catch Up. If you didn't even complete Caravan and only registered for Expedition, you won't receive compensation.
Catch Up costs coins; each Skill Point costs 300,000 Coins, and you can recover a maximum of 5 Skill Points, meaning you need to prepare 1.5 million Coins.
