This page details pre-release information and/or media for Deltarune.
| To do:
- Add comparisons where appropriate.
- The version of the game shown in the 6th Anniversary livestream had some differences to the released versions of the game. These were all/mostly Easter eggs or jokes but may still be worth noting.
- Replace the images with higher-quality versions if possible.
- There's a new official status update on Deltarune! It has some new media from chapters 4 and 3.
|
Deltarune began as a small project by Toby Fox, which was worked on simultaneously with Undertale. That game ended up releasing first, leaving Deltarune to end up having to be both its own thing, along with a pseudo-sequel to Undertale. Despite this, work was being done for the game all throughout the development of Undertale from everything but the actual programming aspect. Development has since sped up, thanks to the addition of an entire team, something which would not have been possible during the development of Undertale.
Summarized Development Timeline
Before 2011
- Unknown; sometime while Toby Fox was in elementary school - Toby's eldest brother develops a RPG Maker game titled "New Genesis". The main character is named Ralse, which Toby would later take the name of and append an I to the end for the name of Ralsei in Deltarune. "New Genesis" is never finished.
2011
- Unknown - During a bout of illness, Toby Fox dreams about an ending to a game that doesn't exist. After waking up, he decides to make that game a reality.
2012
- March 29 - A seemingly regular Tumblr post by Kanotynes depicting a deck of playing cards inspires Toby to develop these designs into actual characters. This post would inspire the characters of Lancer, King, Clover, Rudinn, Hathy, and the other kings seen in the jail.
- April 26 - Early drafts of an unnamed project by Toby are made.
- December - Toby starts to learn about basic programming variables in RPG Maker 2000. He begins to develop an RPG, which would later become Undertale.
2013
- July 17 - Toby adds the final goal to the Undertale kickstarter. If $45000 is reached, he says he will start writing the script to "another game" after development of Undertale is finished. He adds "The "other" game... I can't tell you anything about it. Its very nature is shrouded in darkness. Ha ha ha.".
- August - Toby starts creating concept art of the characters, a month after the Kickstarter for Undertale ends.
2015
- September 15 - Undertale is fully released to the general public. Several references to "the dark" appear, indicating that Deltarune was in mind when creating Undertale.
- December 8 - In the comments to a Reddit post talking about Dreemurr.com, a fan site collecting works by the Undertale community, users discuss deltarune.com and an image called him.png, confirming that they existed by this point. While the post itself is deleted, a screencap survives, revealing that the reason why deltarune.com was discussed was because dreemurr.com originally used that domain before being asked by Toby to change it. Later, one of the commenters, frozenLake123, tweets at Toby asking if deltarune.com is official. They receive no reply.
- December 9 - The first snapshot of him.png appears on web.archive.org. The image, used for the site deltarune.com, appears to be completely black; however, when brightened, it reveals a passage of Wingdings text that translates to "THIS NEXT (space) EXPERIMENT (space) SEEMS (space) VERY (space) VERY (space) INTERESTING", quoting the text from the unused room_gaster in Undertale.
2016
- July 1 - The first complete snapshot of deltarune.com appears on web.archive.org. The website is completely black, except for a new version of him.png on the left. When brightened, the Wingdings passage reads "THREE HEROES APPEARED (space) AT WORLD'S EDGE". This is a direct quote from the Legend in Deltarune, indicating that the Legend (or at least this part) was finalized at this point.
- August 17 - deltarune.com is updated to again revise the Wingdings text in him.png, this time reading "THREE HEROES APPEARED (space) TO BANISH THE ANGELS HEAVEN". This too is a reference to the Legend in Deltarune.
2017
- July - Undertale is released for the PlayStation 4. An Undertale themed PlayStation 4 dynamic menu was release alongside it with a new music titled "Before The Story" plays in the background, which would later be used for the completed file select screen in Chapter 1 of Deltarune.

- September 17 - The Deltarune Chapter 1&2 demo is released. Gaster(?) briefly returns on Twitter a few minutes before the new demo releases. Toby also posts another status update of Deltarune, that mainly focuses on future planning. The soundtrack is released simultaneously with this chapter.
2022
- May 16 - Toby states that "the game development is going well" and that he's brought even more people on-board to assist with development, reinforcing his positivity about the game's direction.
- September 15 - Toby posts a status update confirming that no new releases are planned for the rest of the year, while also noting that development of Chapters 3-5 are progressing at a more efficient pace compared to 1 and 2.

- September 17-18 - Fangamer runs a 24-hour Spamton-themed sweepstakes to raise money in support of flooding victims in Pakistan. The site for the sweepstakes features a number of hidden pages attached to it that reveal a LOT of content and hints related to future chapters, including the characters Shadowguy, Elnina, and Lanino (though their names wouldn't be revealed until a couple years later).
2023
- April 1 - The spring issue of the Undertale/Deltarune newsletter is released, in it Toby provides an update to Chapter 3, stating that the main focus is finishing it and it will soon begin translation to Japanese. He also states in higher tier versions of the newsletter to avoid exploring the files and going into a room full of "four thousand little tree objects" and then writes that a brief segment involving cowboys teased in the sweepstakes "is in danger of being cancelled."
- June 30 - The summer issue of the Undertale/Deltarune newsletter is now out! Toby gives another progress update on Chapter 3 stating that the final overworld area is now being worked on. Toby mentions that he focused on "unusual gameplay elements" for the chapter. He ends off by saying that Chapter 4 will be a more "standard" chapter.
- September 14 - The autumn issue of the Undertale/Deltarune newsletter arrives, celebrating the eight anniversary of Undertale. Toby states that Chapter 3 is now "playable from beginning to end" and that the amount of stuff left to do is now considerably less than what's already been completed. Toby also reveals that a planned stealth section was scrapped from the chapter because "a mechanic which basically just makes you move slower isn't necessarily fun," providing fans with an MP3 file of the segment's theme (which consequently will go unused).
- October 31 - The Halloween issue of the Undertale/Deltarune newsletter arrives, celebrating the fifth anniversary of Deltarune's first chapter. Toby reveals that Chapter 3 is "pretty much content complete" and that development is now shifting focus to Chapter 4, with a new producer being hired to help the team out. Toby also states that the next release will consist only of Chapters 3 and 4, with Chapter 5 being held off until a later date; in light of this, he also states that future newsletters will avoid information on the state of development unless development is close enough to completion or something amusing occurs. To commemorate five years since the release of Chapter 1, Toby conducts an interview with the Chapter 2 development team, revealing various early sprites and test animations.
2024
- February 13 - The Valentine's Day issue of the Undertale/Deltarune newsletter is released. Toby reveals that the Japanese localization of Chapter 3 is currently in the works, and that it will be followed by final porting and bugfixing. The primary focus for the developers at the moment is Chapter 4, which is being developed with an internal deadline in mind; some minor work is also being done on Chapter 5. Toby credits the anonymous producer with helping improve the team's efficiency and expresses confidence in the amount of work that'll be done in 2024. As part of the newsletter, Toby also conducts an interview with concept artist Gigi DG, revealing previously unseen concept art from Chapter 2 and upcoming chapters.
- May 16 - The Spring issue of the Undertale/Deltarune newsletter is released. Toby states that "Chapter 4 development is going better than ever" thanks to the producer and an expanded development team. Chapter 4 is mostly finished, with only a handful of cutscenes, maps, and iterations of an unspecified "gimmick" (in the vein of Chapter 2's spinning teacups) left to work on, plus additional polish for enemy attacks and boss fights. However, Toby states that "the release is still quite far" due to the need to anticipate possible "surprise factors."
- July 12 - Toby would make a thread on Twitter, sharing in a tweet that a couple of his friends had been able to play through Chapter 4. Toby notes that they enjoyed it.
- July 30 - In the Summer issue of the Undertale/Deltarune newsletter, Toby states that their team's goal is to simultaneously release Chapters 3&4 on PC and Console in both English and Japanese, which will take a considerable amount of time to do. As part of the newsletter, Toby includes a link to an overview about the "release quests," featuring snippets of English and Japanese text from Chapters 3&4; these excerpts reveal the names of Elnina, Lanino, and Shadowguy, who were previously shown off in the hidden content in the Spamton Sweepstakes. Said release quests involve public testing for the "game_change" function (which allows for multiple games to be launched in GameMaker), completing the English PC version of Chapter 4, general bugtesting prior to release and many other factors. Toby encourages the reader to keep an eye on the UNDERTALE Twitter account for more updates regarding the new function. He also mentions that a few people are starting map drafts and bullet patterns on Chapter 5.
- September 15 - The Fall issue of the Undertale/Deltarune newsletter is released, celebrating the 9th anniversary of Undertale. Toby reveals that the main content in Chapters 3&4 is all finished. What remains are the following tasks: finishing the Japanese localization (Chapter 3's is mostly complete, with 8-4 now checking the game to see if all the text displays properly, while preliminary work has just started on Chapter 4), finishing bugtesting, and testing the "game_change" function (which is currently on hold until the GameMaker team can step in to assist them). Toby also provides links to two pages detailing previously unreleased concept art and scrapped music.
- October 31 - In a tweet celebrating Deltarune's 6th anniversary, Toby says that Chapters 3 and 4 will "100% come out in 2025". He also adds that the specific time is still relying on localization and console porting.
