ARC Raiders Riven Tides Lands April 28 With a New Coastal Map and Large ARC Enemy

Riven Tides is the fourth and final major update in ARC Raiders' 2026 Escalation roadmap, and it's shaping up to be the biggest content drop the extraction shooter has received since launching in October 2025. A brand-new coastal map, a new large ARC threat, a fresh map condition, and the Expedition 3 sign-up window are all part of the package.

Quick answer: Riven Tides is expected to arrive on April 28, 2026, following the pattern of every previous Escalation update launching on the final Tuesday of its designated month. Embark Studios has not officially confirmed the date.

Riven Tides Expected Launch Times by Region

Previous ARC Raiders updates — Headwinds, Shrouded Sky, and Flashpoint — have all gone live on the last Tuesday of their respective months. Flashpoint did arrive roughly 30 minutes late, so a small delay is always possible. If the pattern holds, here's when Riven Tides should become available.

New Coastal Map in the Rust Belt

For the first time since ARC Raiders launched, players will leave the inland industrial zones behind. Riven Tides introduces a sprawling coastal biome situated in the bottom-left corner of the Rust Belt, directly below Buried City and to the left of Volcano Rise. Embark confirmed the map's position during the Flashpoint update, when an in-game map marker appeared with an "It's here" sticker pinpointing the location.

Concept art and early development imagery point to a dramatically different environment compared to existing maps. Expect sandy dunes, jagged cliffs, flooded urban ruins, and wide-open sightlines along the shoreline — a stark contrast to the tight verticality of Stella Montis. Notable landmarks spotted in concept art include a ringed coastal city that extends into the water with underground sections near the waterline, an offshore platform resembling an oil rig, and a massive rocket ship lying on its side, partially submerged. Whether all of these elements make it into the final map remains to be seen.

Embark has also hinted at a resort-type point of interest through an email sent directly to players. The coastal setting opens up questions about water mechanics, too — whether falling in means instant death or if swimming will be possible could significantly affect how the map plays.

New Large ARC Threat

The Escalation roadmap confirms a new large ARC enemy will debut alongside the coastal map. Embark hasn't revealed what it is, but the leading candidate among the community is The Bishop, a towering ARC threat originally seen in pre-release playtests. The Bishop is expected to use long-range artillery and area denial attacks, punishing Raiders who linger in the open — a fitting threat for a map built around wide sightlines and exposed shorelines.

Another theory floating around is the Emperor, a massive ARC that appears to be moving closer to The Blue Gate in the game's lore. Nothing has been officially confirmed on either front, so the reveal will likely come closer to launch day or in the patch notes themselves.

New Map Condition

Every major Escalation update has introduced a new map condition. Shrouded Sky brought the Hurricane, and Flashpoint added its own twist. Riven Tides will continue the trend with a condition that likely ties into the coastal theme. Exact details remain under wraps, but the expectation is something that obscures player vision or restricts certain paths on the map — fitting for an environment defined by water, tides, and exposed terrain.

Expedition 3 Sign-Up Window

Riven Tides will also open the Expedition 3 sign-up window. This is the same system introduced in earlier Expeditions, where you choose to have your current Raider leave the Rust Belt and start fresh with a new character. It's entirely optional, but signing up gives access to exclusive rewards that have historically included Raider cosmetics, additional stash slots, and skill point bonuses.

If you participated in Expedition 2, the process should feel familiar. The sign-up window typically opens with the update and remains available for a limited time.

Patch 1.24.0 Prepares the Ground

Embark rolled out patch 1.24.0 on April 14 as a pre-Riven Tides maintenance update. It's a bug-fix patch with no new content, but it addresses several stability issues and quality-of-life problems that cropped up after Flashpoint. The key fixes include crash prevention improvements, a fix for the Vanguard Set causing model stretching on other players' screens, an audio bug on Stella Montis where sounds were too quiet without line of sight, and a visual blur issue when AMD FSR Frame Generation was enabled.

Players who contributed to the now-removed Weather Monitor Station Project but couldn't finish it in time have been told to check their in-game inboxes in the coming days for some form of compensation.

Everything Confirmed for Riven Tides

Riven Tides marks the conclusion of ARC Raiders' Escalation roadmap — the four-update content plan Embark laid out in early January 2026. With a completely new biome, a potentially game-changing large ARC enemy, and the Expedition 3 cycle, it's the most ambitious single patch the game has attempted. Full patch notes and official details should surface from Embark in the days leading up to April 28.
