ARC Raiders

Expedition 5's preparation phase is estimated to begin after Expedition 4's automatic departure on July 21, 2026 at 08:00 UTC; its Expedition Window has not been announced. Official Expedition 4 notes state that the +12 stash-space Expedition bonus will max out at 60 with the fifth Expedition, but reward and lock-in details remain unannounced. A July 2026 developer update also confirmed the studio is shifting to twice-yearly major updates while continuing to iterate on the Expedition Project to be more rewarding, but gave no concrete timing for Expedition 5.

The fourth Expedition departure window runs from July 7, 2026 at 11:00 UTC to July 21, 2026 at 08:00 UTC, with signed-up players departing automatically when the window closes. The Expedition Challenge no longer awards Skill Points for fourth-Expedition players; instead, up to five damage objectives award one temporary Blueprint and 150 permanent Raider Tokens each, alongside the first Zenith Outfit step, +12 stash space, catch-up for missed prior Skill Points, and Ermal's Vault support for up to five carried items.

Lock-in: Jul 7, 2026 - Jul 21, 2026
