Saros Zenith update is out: free on PS5 with Overlord Rush, Eclipse Layers and slow game speed

Saros Zenith update: what it is and when it landed

The Saros Zenith update is out now on PS5, free for every Saros owner, Housemarque announced on the PlayStation Blog on October 19, 2026. It adds a boss rush mode called Overlord Rush, a New Game Plus structure called Eclipse Layers, 20 new Carcosan modifiers and a set of accessibility options led by an adjustable slow game speed. Push Square reports a 3.5 GB download and describes it as version 2.0. The PlayStation Blog post gives no version number or file size, so treat both as Push Square's figures until the patch notes say otherwise.

Saros launched on April 30, 2026 at $69.99, according to Push Square, which puts Zenith about five and a half months after release. The PlayStation Blog calls the game "one of the highest rated action games of 2026," which is Sony's own phrasing rather than an independent tally, and we have not checked a review aggregate for this piece. Zenith is not a new campaign. It is a replayability and access update, written up by Abebe Tinari, the Zenith design lead at Housemarque, with two stated aims: give people who finished the game a reason to come back, and make it easier for newcomers to get in.

Overlord Rush: the Saros boss rush mode

Overlord Rush is reached through the Primary Unit in Passage and is framed in the fiction as a training simulation. Players race to defeat the main game's Overlords, and an integrated global leaderboard ranks the results. There are three sets. Incursion and Ascension cover three Overlords each and can be completed in about 10 minutes, per the PlayStation Blog. Totality is the full run: all eight Overlords back to back in one continuous gauntlet.

The detail that matters most for competitive players is that leaderboards can be filtered by main weapon, so a time set with one loadout is not compared against a different one. The blog footnote also says the mode needs an internet connection and a PlayStation account, which means offline players will not be able to use it. A boss rush with a leaderboard is built for repeat attempts rather than a single clear, and ten minutes per set is short enough to make that realistic. We have not played the mode, so how the scoring feels is a question for hands-on coverage.

Eclipse Layers: how Saros New Game Plus works

Eclipse Layers is the Saros equivalent of New Game Plus, as Push Square puts it. It unlocks after you clear the game. New nodes appear in the Armor Matrix at Passage, and activating them opens the gate to the next Eclipse Layer. Each layer changes the rules and makes them more intense. Before you start a layer you pick a loadout of Carcosan modifiers and must reach a required threshold of them to begin, so the difficulty is partly a choice you make before the run.

The Crown ties the system to the story. While you play an Eclipse Layer, protagonist Arjun wears a Crown and his armor glows golden. The Crown grows larger as you take on more Trials and your Modifier Balance rises. Housemarque also adds 12 collectibles called Visions across Carcosa, shown as murals and messages carved by an ancient king, and higher Crown levels are needed to reveal some of their story text. Push Square notes the Crown is required to find the new set of collectibles that unlock more lore. In plain terms, the harder you play, the more story you see.

The 20 new Carcosan modifiers

Zenith adds 20 new modifiers: 10 Protection modifiers that make the game more forgiving, and 10 Trial modifiers that make it harder. With them the game has 25 Trials in total, per the PlayStation Blog. The post spotlights two. Corruption Melee Enhancement is a Protection: corruption absorbed from enemy projectiles is consumed on a melee hit to deal extra damage. Tinari's line for it is "Corruption becomes a new source of power."

The Trial example is Hostile Regeneration. Larger hostiles can be stunned by weapon damage but regenerate quickly, and only a melee strike finishes them. Housemarque also warns that certain Trial combinations synergize in dangerous ways, which reads as an invitation to stack them and find out. Both examples in the post lean on melee, but a post that names two of twenty cannot tell us whether that holds across the set, so we are not drawing a conclusion from it.

Slow game speed, auto-fire and motion aiming: the new accessibility options

Slow Game Speed slows the game so players have more time to react to attack telegraphs and bullets. The attacks themselves are unchanged. Players set how much it slows, and it can activate automatically in combat or be toggled manually, per the PlayStation Blog. That design choice is worth noting: the patterns stay intact, so the skill of reading and dodging them is still the game, just at a pace a wider range of players can manage.

Auto-fire makes weapons fire automatically when aimed at a hostile. It does not touch reloading. Tinari is explicit that "this setting does not make reloading automatic," and a perfect reload still needs a timed button press. Motion Sensor Aiming is a new aiming option, and button remapping, which already existed, combines with the new settings. Push Square's rundown also lists a high-contrast visuals toggle, auto-aim and gyro aiming among the options. Gyro aiming is Push Square's wording, and the PlayStation Blog names it Motion Sensor Aiming.

What the Zenith update means for Saros owners

Free post-launch content on a $69.99 game is the headline here, and Push Square's "massive" description is fair on the content list alone: a new mode, a New Game Plus loop, 20 modifiers, 12 collectibles and a set of accessibility options. Push Square had previewed the update in September as adding boss rush and New Game Plus with more to come later this year, so this release delivers what was promised rather than a surprise.

For players who stopped at the credits, Overlord Rush is the quick way back in and Eclipse Layers is the long one. For anyone who bounced off the difficulty, slow game speed and auto-fire are the real news. Two caveats stand: Overlord Rush needs an internet connection and a PlayStation account, and we have not played Zenith, so this is a report on what Housemarque and Push Square have published, not a verdict. Our play-first assessment will wait for hands-on time.
