I stood over my half-packed caravan at 3:45 AM and realized I had two hours to meet the sign-up window — the clock already smelled of panic. You can feel the same pressure if you’ve been hoarding blueprints, stash slots, or Raider Tokens and don’t want them to vanish. For a handful of players this is a simple gear reset; for others it’s a hard reset of months of progress, moving as urgent as a train leaving the station.
I’ve tracked every expedition cycle and the game’s updates, and I’ll walk you through the exact start time, what you must gather, and which rewards will follow you when you return. Read this as a packing list, a warning, and a promise: small decisions now change what you keep later.
Arc Raiders Expedition 4 Start Date
Most calendars I open this week have at least one reminder for July. Arc Raiders Expedition 4 launches on July 7, 2026, at 4:00 AM PT and wraps up on July 21, 2026, at 1:00 AM PT. The sign-up window has been widened to 14 days so you get more time to stack materials and prepare your loadout.
You can now sign up for the latest Expedition in Arc Raiders!
All Arc Raiders Expedition 4 Rewards
On my last departure I watched players trade months of scavenged mods for a single rare cosmetic — people value permanence. For Expedition 4, the developer has reworked the reward flow: Skill Points are no longer handed out at this level; instead you get blueprints and Raider Tokens, plus a new mystery-reward track tied to damage dealt.
How many expeditions are in Arc Raiders so far?
There are four expeditions released to date. The seasonal rhythm means each major update can add another expedition, but for now you’re facing the fourth run and its specific trade-offs.
Arc Raiders Expedition 4 Damage Requirements and Rewards
The new mystery rewards ask you to contribute raw damage to both human enemies and ARC threats. Hit these cumulative totals to claim the mystery tiers:
- Mystery Reward 1: Deal 5,000 total damage
- Mystery Reward 2: Deal 10,000 total damage
- Mystery Reward 3: Deal 30,000 total damage
- Mystery Reward 4: Deal 50,000 total damage
- Mystery Reward 5: Deal 100,000 total damage
Blueprints
The system guarantees you won’t receive the same blueprint twice as a departure bonus. Blueprints you earn this way are temporary and will be lost if you take part in the next expedition; treat them like short-term test blueprints for experimentation.
- Heavy Gun Parts Blueprint
- Complex Gun Parts Blueprint
- Padded Stock Blueprint
- Extended Barrel III Blueprint
- Muzzle Brake III Blueprint
- Stable Stock III Blueprint
- Vertical Grip III Blueprint
- Venator Blueprint
- Rascal Blueprint
- Osprey Blueprint
- Trailblazer Blueprint
- Anvil Blueprint
- Bettina Blueprint
- Hullcracker Blueprint
- Tempest Blueprint
- Vulcano Blueprint
- Dolabra Blueprint
- Aphelion Blueprint
- Combat Augment Mk 3 Flanking Blueprint
- Tactical Augment Mk 3 Defensive Blueprint
- Looting Augment Mk 3 Safekeeper Blueprint
- Looting Augment Mk 3 Survivor Blueprint
- Wolfpack Blueprint
- Powered Descender Blueprint
- Snap Hook Blueprint
Raider Tokens
Complete each departure objective and you’ll receive 150 Raider Tokens. Those tokens are permanent and do not reset, so finishing all five objectives nets you 750 Raider Tokens.
Permanent Rewards
There are a few things that stick after your departure:
Cosmetics:
- Completing your fourth Expedition grants the first piece of the Zenith outfit.
Bonuses:
- +12 stash space this expedition (48 extra total after the 4th run); stash space reaches 60 at the 5th expedition.
- Expedition bonus skill points cap at 15 total, tied to stash value. Catch-up for missed skill points becomes available starting with your second expedition and closes once you’ve hit the 15-point cap.
Consecutive buffs
If you run expeditions back-to-back you keep growing XP, Scrappy materials, and repair bonuses up to three levels; on your fourth consecutive run those boosted values hold steady rather than increase.
How to Prepare for Arc Raiders Expedition 4: All Requirements
When I open my stash the night before departure, the screen looks like a grocery list gone rogue. The Expedition option becomes available once you hit level 20. If you’re at or past level 20, gather the following materials for each phase of departure:
Phase 1 (Foundation)
| Required Resources | How to get it |
|---|---|
| 150x Metal Parts | Can be crafted, recycled, found in common and ARC loot, or bought from Celeste |
| 100x Chemicals | Can be crafted, recycled, found in common and ARC loot, or bought from Celeste |
| 80x ARC Alloy | Can be recycled or scavenged from ARC enemies |
| 15x Canister | Can be recycled, found in common and ARC loot, or bought from Celeste |
Phase 2 (Core Systems)
| Required Resources | How to get it |
|---|---|
| 30x Durable Cloths | Can be crafted, recycled, or found in common and ARC loot |
| 25x Oil | Can be recycled, found in common and ARC loot, or bought from Celeste |
| 20x Electrical Components | Can be crafted, recycled, or found in common and ARC loot |
| 3x Industrial Charger | Can only be scavenged |
Phase 3 (Framework)
| Required Resources | How to get it |
|---|---|
| 20x Arc Motion Core | Can be bought from Celeste, recycled, crafted, or scavenged |
| 15x Speaker Component | Can be bought from Celeste, recycled, or scavenged |
| 5x Turbine Compressor | Can only be found from ARC Turbine loot |
| 2x Exodus Module | Can be bought from Celeste, recycled, or scavenged |
Phase 4 (Outfitting)
| Required Resources | How to get it |
|---|---|
| 1x Portable TV | Can only be scavenged |
| 5x Advanced Electrical Components | Can be crafted, recycled, or scavenged |
| 2x Sirena Dorata Ship Model | Can only be scavenged |
| 3x Vaporizer Regulator | Can only be found from Vaporizer ARC loot |
Phase 5 (Load Stage)
For the final load, you’ll be donating vast quantities of gear and items. Treat this as the moment you choose which parts of your collection matter enough to keep:
- Combat items: 200,000 (Weapons, Ammo, Mods, Grenades, Traps)
- Survival items: 100,000 (Shields, Quick Use Items, Augments)
- Provisions: 150,000 (Keys, Trinkets, Ship Models)
- Materials: 300,000
Phase 6 (Departure)
Once you hit departure, the system removes the items you donated — most of your collected loot will vanish from inventory except for a handful of protected things listed below. If you want to bring specific items with you, you can buy Expedition Vault Slots from the new trader Ermal (up to five slots).
Can I still do the expedition on Arc Raiders?
Yes. New expedition windows open with major seasonal updates, and the last call feature gives you one more chance to sign up if you miss the initial window. You can start preparing now and join when the departure window opens.
What happens if I miss the expedition on Arc Raiders?
If you skip a departure, your progress does not get reset automatically — only players who take the departure undergo the inventory and blueprint wipe. Missing a run preserves your current stash, blueprints, and level until you choose to depart later.
What Happens in Arc Raiders Expedition 4?
I watched a friend hand over months of scavenged gear and then stare blankly at an empty inventory; departures are that stark. Here’s everything you lose and keep when you go on Expedition 4.
You lose (these are wiped on departure):
- Stash upgrade progress
- Inventory items
- Blueprints (temporary departure blueprints)
- Coins
- Player level
- Skill points (unless they’re the bonus expedition points retained)
- Raider Den
- Workshop
- Active quests
You keep (survivors across runs):
- Unlocked maps
- Codex entries
- Raider Tokens
- Cred
- Raider Decks progress
- Cosmetics
- Trials
- Active leaderboards
- Personal event progress
- Merits
- Bonus skill points earned from past expeditions
- Bonus stash slots earned via previous departures
If you want to bring priority items, buy Expedition Vault Slots from Ermal before you depart. And if you plan to chase the mystery rewards, remember that damage totals stack across your team — coordinate with your squad.
Think you’ll sign up for Expedition 4 or let this one pass?
