Stage name
working title
Named in the public announcement Still open
The news is travelling under a stage name. The project is called RS4, and that string is a working title which may not be the name on the eventual client. A working title is how a game is discussed before the trademark, the logo lockup, and the store listing are finished. Here the numeral is already public, because the concept film ends on a flaming metal 4.
On 5 October 2026 the fourth MMO was still described as as-yet-unnamed. Headlines from the same weekend prefer RuneScape 4. Both can be true at once. The familiar numbered title is what people reached for, while the final name was left unset. The four labels stay apart so a headline is not mistaken for a rename.
The stage name
RS4 is the label on the project itself, paired with a plain warning that the label is not necessarily the final name. That warning matters more than the abbreviation. A search for a finished logo, a launcher, or a locked trademark will not find a finished identity, only a numeral that is already being said out loud.
Use the stage name when you talk about the project shown at RuneFest. Do not treat it as a patch name inside RuneScape or Old School RuneScape. It is not a world event, not a league, and not a Dragonwilds season. It points at a separate game that is still years from a login screen. Until a different title is published, RS4 is the accurate way to refer to the project.
Say RS4 when you mean the October 2026 project, and wait for a later title before you paint a wordmark on a guild banner or a launcher icon. The flaming 4 can stand in for the letters. The letters themselves are still provisional.
Fourth generation
The project is the fourth generation RuneScape game, the fourth MMO in the franchise. That count is about the line of games, not about a ruleset version number inside any one of them. RuneScape, Old School RuneScape, and RuneScape: Dragonwilds are the three experiences already live. The new one is the fourth, and it is early.
Fourth generation does not tell you which engine features, which account system, or which combat rules carry over. The production fact attached to the new project is that it is a RuneScape MMORPG built in Unreal Engine. No engine version is named. The generation label is a place in the franchise, useful when someone asks whether this is a mode inside a game they already pay for.
The fourth slot explains the numeral on the end card, and it explains why people already reached for a numbered title before any letters were locked. Four games in the family, one of them new, is the count. It is not a combat version, not a client version, and not a season number inside Dragonwilds.
Headlines and the recap
RuneScape 4 was already the public spelling on 3 October 2026 and on 4 October 2026. No official name was settled on those days. Players were already using RuneScape 4 for the same early project, while the title itself was still free to change.
On Monday, 5 October 2026, the fourth MMO was still as-yet-unnamed. If a conversation mixes the headline spelling with that Monday status, keep them as two layers. RuneScape 4 is the name people reached for. The final name has not been locked. Each label names a different job: working title, franchise slot, common spelling, or a final name that is still open.
RS4 is the working title. Fourth generation is the franchise slot. RuneScape 4 is the common spelling. As-yet-unnamed is the final name, still open. Using the common spelling in conversation is fine. Painting it on as the finished logo is not, until the letters are actually locked.
| Label | Where | Status |
|---|---|---|
| RS4 | The project | Working title |
| Fourth generation | The franchise | Fourth MMO |
| RuneScape 4 | Common spelling | Not locked |
| As-yet-unnamed | Final name | Still open |
The flaming numeral
Whatever the letters end up spelling, the reveal's picture is a 4 on fire. The concept film holds on that end card, and the share image uses the same flaming metal numeral. It is the one mark you can point at without arguing about the spelling. It also explains why the working title is a number rather than a place name or a saga title.
The end card is not a gameplay interface. There is no health bar, no ability tray, and no login button on it. It is a title card for a film called a first glimpse. The still here is that closing frame, at one minute eighteen. The share artwork is a separate picture of the same fire, so the two are not the same file stacked twice.
When you describe the card to someone who has not watched, say flaming metal and a single 4, not a crest, a finished wordmark, or a button that starts a download. The digit matches the fourth game in the franchise and the working title RS4. It does not spell the final name.
Store search
A shop search for the working title RS4 does not find a RuneScape product. That fits a game which is still a few years away and which does not name platforms. There is no store capsule, no release date, and no system requirements, because the product is not listed. Steam in particular has no RS4 page.
A missing shop page is not a cancellation. The project was on stage at RuneFest and in public the same week, dated 5 October 2026. Read the empty shelf as a boundary. Interest is collected by Jagex's own form, not by a shop button. When a platform list exists, it will be new information. Until then the shelf is empty. What is public is the RuneFest reveal: the working title, the film, the setting, and the form.
Until a shop listing exists, the interest form is the only public action, and even that action does not name a platform or a price. Register interest takes an email and a consent choice. It does not take a payment, and it does not install a client. The working title can be spoken. It cannot yet be bought.
