Search for whether you can play Marathon solo and you get a wall of confident yes-and-no answers, most of them written by people who queue with a full crew and have never actually dropped in alone. The lazy take is that there is a solo mode and you are fine, which is technically true and completely misleading, and if you play the way I do, alone and by choice, the distinction is the whole ballgame. In Marathon, solo does not mean what it means in the games you and I usually live in, because it does not mean a campaign, an offline mode, or a commandable AI squad, and it means you queue without teammates into the same shared extraction map as other human players. You are against other lone scavengers, or against three-stacks who absolutely will third-party you, and the map throws AI enemies and hazards at everyone, while the real threat, the thing that ends your run, is another person. That is the honest framing, and Bungie does not hide it, since the Steam page literally pitches scavenging alone or with a crew as a choice, rather than as a separate PvE game you can wall yourself inside.
The release, and the launch that never happened
Marathon released on 5 March 2026 for PS5, Xbox Series X/S, and PC, with full crossplay and cross-save, and on Steam it is £34.99 standard and £49.99 deluxe as of mid-2026. If that date surprises you, that is because the launch you might remember, the September 2025 one, never happened, after the April 2025 reveal and closed alpha got hammered, Bungie pulled the cord and delayed indefinitely in June 2025, and the March 2026 version is the recovery build. I went through that whole arc in Marathon’s rough ride and the PvE pivot and the longer Bungie extraction recovery breakdown, so I will not re-litigate it here, though it matters, because the question of whether there is solo PvE is exactly the pressure that reshaped this game, and I would rather you buy the recovery build with that history attached.
Vault Breaker, and the catch that comes with it
As of mid-2026 Bungie has announced Marathon’s first true PvE-only mode, Vault Breaker, landing on 21 July as part of the Season 2 Nightfall mid-season update, and this is the one that actually answers the solo player’s prayer, sort of, with the limit sitting in the small print rather than the headline. It drops you into the Cryo Archive map and sends you through a roguelite chain of increasingly nasty vaults packed with AI, toward a final vault and whatever is waiting inside, and crucially you can run it solo, as a duo, or in a trio, with no rival humans in the room. The catch, and it is a big one, is that Bungie is framing it as an experimental, limited test, not a permanent pillar of the game, while standard loot does not extract and only a new currency called Vault Data comes home with you. So it is a low-risk PvE sandbox bolted onto a PvP game, rather than a conversion of the game into the solo loop a lot of us meant when we typed the question.
If you want a tense looter where the danger is other people and you fancy testing your nerve alone, Marathon will give you that, and Vault Breaker in July is worth a look as a no-PvP breather between the queues that actually define the game. If you came here wanting an open-world PvE extraction loop you can grind solo for hundreds of hours, which is the thing most of us actually mean by a solo game, Marathon is not built for that, and a limited summer event does not change the shape of the base loop. The base loop is PvP and is staying PvP, Season 3 lands on 22 September, and the headline changes are about the early-game experience rather than a PvE overhaul.
Where I would send a solo player instead
The obvious comparison is the other extraction shooter solo players keep circling, and I put them head to head in Arc Raiders vs Marathon, where Arc Raiders is the more PvE-forgiving of the two and probably the better fit if human opponents are a dealbreaker for you. Beyond that, the Solo Play Index is where I keep the games that genuinely respect playing alone, and if you are on the fence about spending the £35, run it through should I buy it before the price does the deciding. Yes, you can play Marathon solo, but as of mid-2026 that means solo PvP in a shared extraction map, rather than a single-player PvE game you can disappear into. The Vault Breaker mode on 21 July is the closest thing to real solo PvE, and it is an experimental test with no loot extraction, not the core game, so buy it for the PvP tension and not for a solo campaign that the store page is not selling. More tactical-shooter and extraction breakdowns live over in the intel index, which is where I would go once the yes has been properly qualified and the wallet is still closed.
FAQ
Can you play Marathon solo?
Yes, you can queue alone, but it is solo PvP rather than single-player, because you drop into the same shared map as other human scavengers, either other solo players or three-person crews, and they are the main threat. There is no offline mode and no AI squad to command, and as of mid-2026 the only PvE-only option is the experimental Vault Breaker mode arriving 21 July, which is solo-playable and still not the campaign people mean when they search this.
Is Marathon a PvE or PvP game?
It is fundamentally a PvP extraction shooter, so you loot, fight AI enemies and environmental hazards, and try to extract, while rival human players stay the core danger. Bungie has added PvE elements in the form of AI enemies, and a dedicated PvE-only test mode called Vault Breaker, but the base loop is built around player-versus-player extraction and the studio has not pretended otherwise.
When did Marathon release and how much does it cost?
Marathon launched on 5 March 2026 on PS5, Xbox Series X/S, and PC through Steam, and on Steam it is £34.99 for the Standard Edition and £49.99 for the Deluxe Edition as of mid-2026. It supports full crossplay and cross-save across all three platforms, so the box you buy it on is less of a cage than the price, which is the part I would check before the queue time.
What is Vault Breaker in Marathon?
Vault Breaker is Marathon's first true PvE-only mode, launching July 21, 2026 as part of the Season 2 mid-season update, set in the Cryo Archive map and playable solo, as a duo, or in a trio. You work through a roguelite chain of increasingly tough vaults of AI enemies toward a final vault, and it is framed as an experimental, limited test rather than a permanent pillar, while standard loot does not extract and only a new currency called Vault Data carries out.
Is there crossplay and cross-save in Marathon?
Yes, as of mid-2026 Marathon supports full cross-platform play and cross-save across PS5, Xbox Series X/S, and PC, so your progression follows you between platforms. That part is settled even while the solo question is not, which is why I separate the account features from the thing that actually ends a run.

Marathon Season 2, Nightfall, is a fair reason to jump back in after the 2 June start, with a new Night Marsh zone, a Sentinel shell, two weapons and The Cradle, and the Season 1 wipe means the old stash is gone on purpose. It is a solid PvP-first season whose problem was Sony's sales expectations rather than the gunplay, so I would go in for the tension and not for a quiet AI evening.27 Jun 2026Read
