Yes—but “solo” and “offline” are separate questions. Grounded, Subnautica and Conan Exiles support playing alone, while Fallout 76 lets you quest solo but requires online play. Your choice depends on whether you need a game that works without an internet connection, want optional co-op, or are comfortable with an always-online world.
Solo play is not the same as offline play
A survival RPG can offer a complete one-player experience and still require an internet connection. “Solo” describes how many people are playing; “offline” describes whether the game can function without connecting to its online service.

- Solo: You can play without another human in your session. The game may still connect to the internet.
- Offline: The game does not require an internet connection for the relevant mode. This is the stricter requirement.
- Optional online: You can play alone, but co-op or competitive features are available when you connect.
- Online required: Even a solo quest or private-feeling session needs an internet connection.
That distinction is why Fallout 76 belongs in a different category from the other three games. It provides solo questing, but its PlayStation listing explicitly says “Online play required.”

Grounded: solo-friendly with optional online co-op
Grounded supports one-player play and is designed to work as a survival adventure whether you are alone or joining friends. PlayStation describes the choice directly: “Explore a vast garden environment alone, or with the aid of up to three friends in online multiplayer.” That means a session can contain up to four online players in total.
What solo players get
You can begin and progress through the backyard experience without inviting anyone else. The one-player option is useful if you prefer to gather resources, build and explore at your own pace, or if your friends are not available. Because online multiplayer is optional, the game meets the practical “can I play alone?” test.
What changes when you go online
Online play expands the session to a small group rather than changing the basic choice between solo and multiplayer. Grounded also lists Shared Worlds, a feature that lets a group continue a shared backyard instead of limiting progress to the original host’s active session. To use online multiplayer, PlayStation Plus is required.
Does Grounded work without Wi-Fi?
The listing’s optional-online wording makes Grounded a candidate for solo sessions, but “optional online” should not be treated as a guarantee that every service, update or account function works without a connection. If no-internet play is essential, verify the current regional listing and test the installed version before relying on it for travel or an outage.
Subnautica: the clearest one-player and offline-oriented choice
Subnautica is presented on PlayStation as a one-player survival adventure. The cited page lists no multiplayer mode and no online multiplayer requirement, giving it the strongest offline fit among these four games.
Four ways to play
The PS5 listing identifies four modes, each aimed at a different balance of pressure and freedom:
- Survival: the standard survival approach, combining exploration with the game’s survival systems.
- Freedom: a less demanding variant for players who want the world and exploration without the full survival burden.
- Hardcore: the most punishing option, intended for players who accept a high-consequence challenge.
- Creative: a freer building and experimentation mode.
These modes make Subnautica easier to tailor to a solo player’s preferred pace. Someone looking for a demanding survival loop can choose Survival or Hardcore; someone primarily interested in discovering the setting and constructing can choose Freedom or Creative.
Why it is the best offline fit here
Unlike a game whose listing says online play is required, Subnautica’s cited description is explicitly single-player and does not state an online multiplayer requirement. That is the clearest evidence in this group for a player who wants to be alone and avoid an online session. The absence of a listed requirement is still worth rechecking against the current regional store page, especially after a platform or service update.
Conan Exiles: the broadest multiplayer range
Conan Exiles explicitly supports “full single-player, co-op, or persistent online multiplayer.” It therefore covers the widest range of play styles in this comparison: a private solo game, a cooperative session, or a larger ongoing online world.
Playing entirely alone
“Full single-player” is stronger wording than merely saying that solo questing is possible. It identifies a complete solo mode rather than a multiplayer game that happens to let you avoid other players. If your main requirement is to play alone while retaining a substantial survival experience, Conan Exiles meets that requirement.
Co-op and persistent worlds
When connected, Conan Exiles supports co-op and persistent online multiplayer. The current PlayStation listing gives a maximum of up to 40 online players. That capacity is much larger than Grounded’s four-player limit and allows a server-style experience for groups that want an ongoing shared world.

PlayStation Plus is required for online play. You do not need that subscription for the game’s supported single-player mode, but you do need it when you move to online co-op or a persistent online session.
Fallout 76: solo questing, but never offline
Fallout 76 is the important exception for anyone searching specifically for an offline PS5 survival RPG. You can approach its quests alone, but the PlayStation Store listing states “Online play required.” Solo activity therefore describes your play style, not the game’s connection requirement.
Rank #2
- Explore a vibrant, living city by foot, squad car and helicopter
- Respond to sandbox crimes ranging from parking violations to gang shootouts
- Engage in intense vehicle chases through destructible environments
- Go solo or call-in backup with an in-depth support system
- Investigate the gangs who rule the city and the dark conspiracies keeping them in control
What “solo” means in Fallout 76
You can quest without forming a group and treat the game as a personal progression route. That can satisfy a player who wants to avoid coordinating with friends or competing for objectives. It does not satisfy a player who needs the console to remain disconnected from the internet.
Online world size and PlayStation Plus
The listing supports up to 24 online players. Because online play is mandatory, PlayStation Plus is required for the online service. The subscription requirement is not an optional add-on in the way it is for a game with a separate offline or single-player mode.

Which game fits your requirement?
If you need the strongest offline candidate
Start with Subnautica. Its cited PlayStation description is single-player, lists no multiplayer mode and gives no online multiplayer requirement. Its four modes also let you choose between traditional survival, reduced pressure, high difficulty and creative freedom.
If you want to play alone now and invite friends later
Grounded is built around one-player play with optional online multiplayer for up to four players. Conan Exiles offers the same basic flexibility but scales much further online, with co-op and persistent multiplayer for up to 40 players on the listing.
If solo story-style questing matters more than being offline
Fallout 76 allows solo questing, but you must accept an online connection and a PlayStation Plus requirement. It is suitable for an online-only player who wants to progress independently, not for an offline player.
If you want a persistent shared world
Conan Exiles is the clearest match among these options because its listing explicitly includes persistent online multiplayer. Grounded’s Shared Worlds feature is a smaller-group alternative, while Fallout 76 provides an online world with up to 24 players but does not offer an offline mode.
How PlayStation Plus fits into the decision
PlayStation Plus matters when you use online multiplayer, not simply because a game appears on PS5. The practical rules for these titles are:
- Grounded: PlayStation Plus is required for online multiplayer; solo play is available without choosing the online mode.
- Subnautica: no online multiplayer requirement is listed, so there is no listed multiplayer subscription requirement.
- Conan Exiles: PlayStation Plus is required for online co-op and persistent multiplayer; full single-player is supported separately.
- Fallout 76: online play is required, and PlayStation Plus is required for that online play.
Subscription policies can be revised, and requirements may differ by region or edition. Treat the current store page as the final check before purchasing a subscription.
How to verify offline and multiplayer support before you buy
- Open the current PS5 or PlayStation Store listing for the exact edition. Do not rely only on a trailer, an old box description or a third-party summary.
- Find the player-count and online-play statements. Look for wording such as “one player,” “up to four online players” or “online play required.”
- Separate the two checks. A one-player label answers whether you can play alone; it does not automatically answer whether the game works without an internet connection.
- Check the PlayStation Plus line. Confirm whether the requirement applies only to online multiplayer or to the game’s entire operating model.
- Confirm the region and edition. Store pages and online-service requirements can change, and the listing for one edition or region may not match another.
- Test before depending on offline access. Install the game, launch the intended mode and verify it while disconnected if playing without internet access is important. Keep the listing’s current wording as your reference if the service changes later.
Common mistakes when choosing a “solo” survival RPG
Mistaking a solo route for an offline mode
Fallout 76 demonstrates this mistake exactly: solo questing exists, but online play is required. Always look for a separate offline or single-player statement.
Assuming optional multiplayer means every feature is offline
Grounded and Conan Exiles make online play optional at the game level, yet online-only features such as shared worlds, co-op and persistent servers still need a connection and, where stated, PlayStation Plus. Decide whether you need the base solo mode or a specific online feature.

A four-player limit is appropriate for a small co-op group, while Conan Exiles’ listed limit of 40 supports a much larger persistent community. Fallout 76’s listed limit of 24 sits between those models but remains online-only.
Ignoring mode selection
Subnautica’s Survival, Freedom, Hardcore and Creative modes offer materially different experiences. Choose the mode before judging whether the game’s survival pressure suits you; the one-player format alone does not describe the whole experience.
Bottom line by requirement
| Your requirement | Best match from this group | Reason |
|---|---|---|
| Play without another player and with the strongest offline case | Subnautica | Single-player presentation, no listed multiplayer mode and no listed online requirement |
| Solo play with optional small-group online co-op | Grounded | One-player support, optional online multiplayer and up to four players |
| Solo, co-op or a large persistent online world | Conan Exiles | Full single-player plus co-op and up to 40 online players on the listing |
| Solo questing in an online-only world | Fallout 76 | Solo questing is available, but online play is required and up to 24 players are supported |
For a strict no-internet requirement, begin with Subnautica and verify the current regional listing. For flexible solo play with the option to connect later, Grounded and Conan Exiles are the clearer choices. Choose Fallout 76 only if an always-online connection is acceptable.
