While Returnal has established itself as one of the PS5’s boldest and more uncompromising releases, studio Housemarque appears poised to build on its foundation in meaningful ways. Through mesmeric, fast-paced gunplay against hostile alien lifeforms, experienced through repeated runs, the two titles share clear DNA. Yet, the closer you look, the more differences you’ll discover.
We’ve already covered SAROS in detail through two other “15 Things” articles, so you won’t see us talking about parries, shields, corruption, or the mysterious eclipse here. Instead, we’re looking at how SAROS’ progression systems, combat flow, narrative tone, and overall structure reflect a design intent that’s markedly distinct from Returnal. Some border on philosophical diversions, sure, but they’re big differences none-the-less. Here’s fifteen of them.
Note: All information in this article is through official sources.
Run Structure
Returnal is built around uninterrupted momentum, where you’ll push through one biome to the next in a single run. SAROS, in contrast, breaks flow into segmented excursions, if you choose to play it that way. Rather than committing to a full-length run every time, you can tackle the sequel’s hostile planet Carcosa in smaller, more focused outings, returning to hub area The Passage to retool and recuperate. This is a fundamental change in pace and structure between the two titles.
Session Design
This shift in run structure bleeds directly into session length. Returnal’s runs can stretch into long sessions, demanding you sustain focus the deeper Selene travels into Atropos. SAROS, instead, appears designed for short bursts, with thirty-minute expeditions that are easier to maintain intensity, knowing The Passage is available any time. This design decision reflects Housemarque’s desire to make SAROS more approachable than its predecessor. The option for episodic runs, with pause for story context and levelling up in-between, might just encourage longer sessions. Of course, not everyone will want a break between biomes. If that’s you, know that SAROS’ levels can still be tackled back-to-back.
Failure Penalty
Speaking of design, failure in Returnal is modelled on punishment, where your progress is near-completely wiped. When Selene’s back at the Helios, it often feels like you’re starting over. SAROS softens this blow by offering more permanent progression systems. The sequel allows you to retain meaningful upgrades between runs, resulting in a loop that feels less about losing everything and more about consistently moving forward.
Your Motivation
Because of SAROS’ upgradable skill tree, your motivation will naturally shift. In Returnal, your mindset is bent on surviving, brute-forcing onwards, and taking care not to make a mistake. SAROS, instead, leans intentionally towards optimism, where you’re encouraged to think about build synergy, how each run contributes to long-term growth, and how to boost each excursion’s efficiency beyond exploiting shortcuts.
Progression Philosophy
This motivational difference – survival vs optimism, desperation vs growing confidence – suggests a wider philosophical divide. In Returnal, encounters often left you feeling like you’re hanging by a thread, where a single misstep could undo hours of progress. SAROS, on the other hand, fosters a sense of control, where success is continually within grasp. Through permanent upgrades, each run reinforces the feeling that you’re entering the fray better equipped to handle what lurks ahead.
Resource Philosophy
SAROS’ shift in mindset is reflected in its resource gathering too. See, in Returnal, most resources are tied to individual runs and lost upon death, while SAROS reframes resources as long-term investments – more rogue-lite, less rogue-like. It’s less of a high-risk structure than Returnal, where you’ll acquire tools to build into future attempts rather than rely on what you find for just a fleeting advantage.
Build Identity
So, what does this shift in resource philosophy ultimately lead to? Well, in SAROS, you can imbue your identity more precisely into a specific build. Because, yes, as we’ve already alluded to, in Returnal your builds are largely shaped by what you find during a run. SAROS gives you more agency outside of runs, losing Returnal’s knack of forcing you to adapt on the fly. What you get instead is the ability to shape and refine your build over time, to pursue your own playstyle and make your survivability hinge on intentional decisions rather than reactive ones.
Difficulty Curve
The way each title delivers difficulty also appears to differ. Returnal throws you in at the deep end, demanding you lean into its specific challenge, oftentimes learning through repeated failure. SAROS’ difficulty appears to scale more gradually, where challenge grows in tandem with your progression, upgrades, and builds, creating smoother onboarding without sacrificing depth.
Combat Readability
Despite frequent bouts of desperation and chaos, Returnal’s combat is built on clarity. Enemy patterns, as bewildering and balletic as they often are, are designed to be readable. Incoming projectiles are visually distinct, and your survival often comes down to skill and instinct. SAROS, by comparison, appears to increase your cognitive load, layering more variables into each encounter – we touched upon the various bullet-types Carcosa’s monsters will spray at your in our other “15 Things To Know” features, but what we didn’t say is this: in SAROS, it isn’t just about you executing quick reactions through movement anymore, but, now, you’re forced to make rapid decisions under enemy fire.
Combat Rhythm
This added complexity feeds into a wider shift in combat rhythm. To survive, Returnal often required a mix of caution and precision. SAROS, instead, brings a more aggressive ethos, where taking risks in battle can lead to greater rewards. This is another fundamental change between the two games, altering the rhythm of combat encounters entirely.
Spatial Awareness
If combat rhythm has shifted, you can bet movement and positioning will also play out differently. Returnal places heavy emphasis on verticality, where you’re constantly navigating upwards, downwards, and across arenas. SAROS, from what we’ve seen, appears more focused on lateral movement and spatial awareness. There’s still opportunities to extract positional advantages through elevation, but overall SAROS seems more grounded, changing how you’ll read and control spaces during combat encounters.
Encounter Framing
Tweaks in your spatial awareness aren’t just a by-product of more lateral level design, but encounters on the whole seem to be framed differently too. Where Returnal often throws sudden ambushes and reactive combat scenarios at you, SAROS – again, from what we’ve seen so far – seems to favour more structured fights. The result: you’ll enter encounters with a greater sense of anticipation, meaning higher chance you’ll be able to execute those on-your-feet decisions that we mentioned earlier through deliberation.
Narrative Delivery
We’ve already highlighted in our SAROS coverage elsewhere how the two titles narratively differ, but their tone and delivery diverge significantly too. Selene’s experience in Returnal is solitary and introspective, exploring themes of memory, guilt, and repetition. SAROS introduces a more interpersonal dynamic, where psychological strain, and environmental instability shape a more outward-facing narrative that is delivered, in part, during Arjun’s time back at The Passage.
Replayability
Replayability is another area where the two titles differ in approach. Returnal’s consistent repetition encourages you to refine your skills through consistent and familiar loops. SAROS, instead, introduces an emphasis on variation, pushing you to experiment with different builds, strategies, loadouts, and approaches across runs, facilitated further by the ability to teleport directly into already completed biomes.
Design Intent
Through Returnal’s announcement and subsequent launch, it became clear that despite switching to third-person perspectives, the game was an extension of Housemarque’s arcade roots – tight, punishing, skill-driven, bullet hell action. SAROS brings the next logical step, building on Returnal’s foundation with broader systems and more flexible design. It positions itself as an evolution of Returnal itself, exuding the studio’s DNA in a grander, more realised experience.
