Invitation
Sign up now
Named in the public announcement Still open
Players can sign up now and register interest, so the game can be built with them. That is the early line: the project is still a few years away, and the news is public now because players are wanted in while it is built. Register interest opens Jagex's page, where the form lives.
The form is Jagex's. It asks for an email, a consent choice covering analytics and personalised advertising, and a button labelled Register interest. The address is entered there, once. What you receive afterwards, and when a test might start, has not been set.
The official ask
Sign up now is the verb, and it is not buried. It is paired with the reason: the game is meant to be built with you. The ask is public in the same week as the first glimpse, which is unusual for a game that is still years from a client, and the timing is explained instead of pretending the client is close. You are being invited into a mailing relationship, not a download.
Build it with you is aspiration plus a form. It matches the principle of community driven development without adding a vote. Registering does not put you on a design committee. It tells Jagex you want to hear more, under the consent text shown with the form. A poll, a forum rank, or a beta contract are not what the button does. The button does the thing printed on it.
The verb is sign up, the reason is the early invitation, and the object of the verb is an email relationship rather than a client. RS4 is still a few years from a login. The form does not change that distance. It only records that you want to be included while the distance is still long.
Email and consent
The form takes an email address. Beside it, Jagex asks for consent related to analytics and personalised advertising. Read that wording at the moment you tick it, because that wording is the one that binds. A paraphrase can turn a checkbox softer or harder than it is. The practical shape is simple: an address, and a permission about how Jagex may contact and measure.
Type the address on Jagex's form, at play.runescape.com/4. A copy of the form on a fan site would be a place for the address to go somewhere Jagex did not ask it to go. The link opens that page in a new tab. If the labels change later, the live form changes with them. Today the fields match the October 2026 form: email, consent, Register interest.
Read the consent on Jagex's page at the moment you tick it. The permission covers analytics and personalised advertising. It is not a payment approval, not a beta contract, and not a transfer of an existing RuneScape character. If you do not want the address on file, you can watch the film and the setting notes without sending it.
No promised reward
Nothing has been promised after you register. There is no list of letters, no cadence, and no statement that a test will open for people on the list first. There is also no statement that you receive nothing. The gap is the fact. Anyone selling a guaranteed alpha key in exchange for a signup is not describing the form.
The open play-date sits right next to this gap. When you can actually play remains too early, even for people who sign up. A few years away still applies to the list. Much more next year, about the world, the game, the team, and how to get involved, is the nearest promise of further news. It is a promise to players in general, not a reward tier for the form. Sign up if you want Jagex to have the address. Do not sign up as if it were a purchase.
No promised letter, no promised key, no promised test: the form is a way to be known, not a shop. No price is attached, because membership itself has not been set. An email is not a bond, not a subscription, and not a pre-order.
Build it with you
Build it with you is the emotional half of the early reveal, and it is easy to overread. It says the studio wants players in the conversation while the game is early enough to be shaped. It connects to co-development learned on RuneScape and Old School RuneScape, and to the named principle of community driven development. It does not name a channel beyond the form.
While the channel is only an email, the involvement you can actually take is narrow. You can give the address or not. You can watch the concept film, read the three principles, and keep the open questions in view, and you can wait for the next-year telling. That is a real role. It is not a job on the separate RS4 team, and it is not a vote that binds the dedicated teams still working on the other three games. The phrase is an open door. The door currently leads to a form.
An open door that leads to a form is still an open door, and it is not yet a workshop with seats and votes. The separate RS4 team is a staffing fact. The form does not hire you onto it. The three living games keep their own people either way.
Where the form lives
The form sits with the working title, the setting, the five commitments, and the teaser, all at play.runescape.com/4. The signup is not on a separate campaign site. Look at the page you land on. You should see RS4, Ashenfall, and the Register interest action. If a link in a chat points somewhere else, it is not this form.
The form does not replace the unanswered list. Platforms, accounts, membership, progression, combat, skills, and a playable date stay open whether or not your email is on file. The invitation and the limits were published together. Keeping them together is how you stay oriented while the game is still a few years from a login and the studio has asked, already, to build it with you.
play.runescape.com/4 is the address of both the news and the form. The button label is Register interest. The fields are an email and a consent line. That is the whole public action, and it still does not name a platform, a price, or a test date.
