Embark Studios’ third Expedition Window for ARC Raiders will open 58 days after the second window closed, which places the start on April 29, 2026. Players who want to participate should begin preparing now because the Project carries multiple large material and currency requirements, and the departure confirmation is only a few days after the window opens. Embark is adjusting rewards and requirements between Expedition cycles, and progress already made toward the previous Expedition Project will still be saved when the third Project appears. The live countdown is visible when a player previews the Project in-game.
The studio typically gives raiders roughly four to five days after the Expedition Window opens to confirm their departure, so assuming the same cadence, the wipe and departure confirmation are expected around May 3, 2026, but Embark has not confirmed exact confirmation dates. Previous reporting noted players pressing for clearer details as the second Expedition window ended, and this edition follows the Shrouded Sky update that introduced the second Expedition and the Surgeon Raider Deck, see earlier coverage linking players demanded clarity and the Shrouded Sky patch for context.
Completing the Expedition Project is a multi-step process. The Project again uses six stages, and each stage contains four requirements made up of materials, ARC parts, and coin-value donations. The fifth stage is the largest single hurdle because its four donation requirements add up to 750,000 Coins in total.
| Expedition Project Stage | Expedition Project Requirements |
|---|---|
| Stage 1: Foundation |
|
| Stage 2: Core Systems |
|
| Stage 3: Framework |
|
| Stage 4: Outfitting |
|
| Stage 5: Load Stage |
|
| Stage 6: Departure |
|
Stage five’s four donation lines add up to 750,000 Coins, and players should plan their resource sales and hoards accordingly if they want to reach the top stages before the window closes. If players do not finish the Expedition before the window ends, any progress saved from earlier attempts will carry over to the next time the Project appears, so partial work is not lost.
