ARC Raiders Expedition 5 Starts September 8: Final Chance for 60 Stash Slots & Zenith Outfit

Summary:

Expedition 5 marks the final 2026 Expedition cycle for ARC Raiders. Running from September 8 through September 29, this three-week event grants permanent stash space bonuses leading to the 60-slot maximum, the complete Zenith Outfit, Mystery Rewards, and bonus Skill Points. Players looking to optimize their pre-event stockpile and Caravan preparation can also check out ARC Raiders Items before the Expedition begins. After this window, the entire Expedition system will enter a long-term overhaul pause and will not return until early 2027. There is no “last-call” grace period, so players must sign up within the official window to secure their rewards, making careful pre-event stockpiling and Caravan preparation essential for all Raiders.

1. ARC Raiders Expedition 5 Start Date and Schedule

The fifth Expedition opens on September 8 at 11:00 UTC and closes on September 29 at 08:00 UTC. The window has been extended from the previous two weeks to three weeks, giving players more time to prepare and commit to their departure.

There is one important catch: there will be no Last Call feature this time. Completing your Caravan is not enough. You must actively sign up during the Expedition window or you will miss the departure.

This makes September 8 an important preparation deadline for anyone who wants to finish their Expedition progression before the long break.

2. The Biggest Reward: Complete Zenith Outfit

For players who have followed the Expedition system since launch, Expedition 5 is especially important because it provides the final piece needed to fully unlock the Zenith Outfit.

The reward track also includes Mystery Rewards and another +12 stash-space increase, taking the maximum stash capacity to 60 slots. For an extraction shooter where inventory management directly affects farming efficiency, those additional slots are arguably more useful than a cosmetic alone.

If you have already completed earlier Expeditions, this is effectively the final step in the current progression chain.

3. Quest Reset Is Now Optional

Expedition 5 also addresses one of the most frustrating parts of previous Expeditions: repeating the same quest progression.

This time, quest reset is optional. Players can choose to preserve their existing quest progress instead of starting the quest chain over after departure. Alternative ways to obtain the Hullcracker Blueprint will also be available because its original quest-line requirement could otherwise become problematic.

For experienced players, keeping quest progress is the obvious choice unless you specifically want to repeat the progression for additional objectives or resources.

4. Prepare Your Stash Before You Depart

Do not treat Expedition 5 like a normal weekly reset.

Before signing up, clean out unnecessary materials, organize valuable loot and make sure your Caravan preparation is as efficient as possible. Players who are close to previous Expedition skill-point thresholds should also consider whether they can complete the available catch-up requirements.

Expedition rewards can include additional Skill Points, with the overall Expedition bonus capped at 15 points. Existing consecutive buffs covering XP, Scrappy materials and repair value can also reach their current maximum levels and persist during the upcoming pause.

5. What Happens After September 29?

This is the most important reason to take Expedition 5 seriously.

Expeditions will be paused until early 2027 while the system receives larger changes. The planned adjustments focus on accessibility, reward structure and the overall Expedition experience.

Players who have unfinished Caravan progress will not simply lose its value. When the system resets, partially completed Caravans are converted into Ermal Vouchers, which can be used for Ermal offers or sold for Coins.

Final Verdict

Expedition 5 is not a routine ARC Raiders event. It is the final opportunity before the Expedition system disappears for the rest of 2026.

If you want the complete Zenith Outfit, additional stash capacity, remaining Skill Points or the strongest possible consecutive buffs, sign up as soon as the window opens. Players who want to prepare their resources ahead of the Expedition can also consider buy ARC Raiders Items before committing to their Caravan. Most importantly, do not wait for a Last Call notification—there will not be one.

With a three-week departure window and optional quest reset, Expedition 5 is more accessible than previous cycles, but players still need to actively register. For serious Raiders, September 8 should be treated as a major progression deadline.
