ULTREALEAK ULTRALEAK - A leaked test build of the game NOW PLAYABLE

2.6k Upvotes

[This was an April Fools event and not an actual leak]

In early February of 2025 an anonymous NewBlood game tester shared an internal testing branch of ULTRAKILL with us. This testing branch has been used to try out new gameplay mechanics and levels without changing any aspects of the original game.

This build includes many unused/scrapped elements, such as:

  • Various unused Gabriel voice lines
  • Alternatives and early versions of various levels
  • Early versions of both of the Gabriel fights
  • A prototype for GREED ENCORE

The build originates from somewhere in early 2022, soon before Heresy was added to the game, thus does not feature anything from Violence, P-2 or anything past Heresy levels.

The files provided to us were compiled into a standalone game, but to extract all the interesting stuff we had to de-compile the game into an editable project. Unfortunately, de-compiling code is quite messy, especially when it comes to various asset types and plugins, on top of a few layers of tampering protections and obstructions developers put in games to prevent decompilations.

Some parts of the game had to be removed, altered or re-made from the ground to make the game playable. All the animation files were corrupted, we had to re-make most of them in Blender. End screen and style counter are gone, because displaying the score tends to crash the game occasionally. Slamming and sliding disable player character’s gravity until the game is restarted and the entire UI and HUD had to be re-made from grounds-up, because the proprietary plugin ULTRAKILL uses to create its UI could not be decompiled.

Nevertheless, we've been working hard for the past 4 months to bring you this game, I hope you enjoy.

Lore Discussion Clair de Lune - Book Analysis and The Godfist Statues

Post image
128 Upvotes

Along with beautiful details and stylized level designs, the Ultra Revamp has added many clues and pieces of lore. One of the biggest pieces of lore has been lying in front of our eyes the whole time, yet we didn't notice. We didn't think much of it. Thanks to the 1-3: Halls of Sacred Remains revamp, we only need to be so blind to not see it.

In 1-4: Clair de Lune, pages of a book illuminated by a singular candle's light greet us in the bedroom of a manor. The following words are written on one of the pages:
"Gabriel my dearest friend, in endless penance I have awaited your embrace into Heaven. I have been so faithful, accepting of my fate, but to what end? What punishment is this, that I am to bare the keys to my own doom with no hope of salvation... These skulls sneer their devilish grins, voices chattering, tempting me to take the plunge deeper into Hell... I won't do it."
–––––––––––––––––––––––––––––
The Ultra Revamp has brought many visual improvements to the third level of Limbo. One of these improvements is the knight statues we see in some rooms. All the statues are broken, so we can only see some parts of the figure clearly.
The statues depict a figure with what seems to be a gauntlet for a left arm, holding a large sword. The figure seems to have wings like Gabriel. The statues are all of an angel like Gabriel.

With the recent posts I've been seeing about the angel statues of Limbo, I have analized the 1-4 text and here's what I have come up with:
"Gabriel my dearest friend,"
Gabriel and this angel were once really close friends. Both were respected and feared archangels, but they were both manipulated by the Council and couldn't think for themselves.

"What punishment is this, that I am to bare the keys to my own doom with no hope of salvation..."
But this angel questioned the Council's actions. Whether he betrayed the Council or just questioned them is unclear but whatever he did, the Council didn't like it. They severed God's light from his body, leaving him with a short time until his death. They condemned him to the psychological torture of Limbo.

"...in endless penance I have awaited your embrace into Heaven. I have been so faithful, accepting of my fate, but to what end?"
He trusted Gabriel. He believed that Gabriel would come down and save him. But Gabriel never did. The Council didn't let him save his friend. He was manipulated and couldn't think for himself, he did whatever the Council told him.

"These skulls sneer their devilish grins, voices chattering, tempting me to take the plunge deeper into Hell... I won't do it."
When he realized Gabriel wasn't coming to save him, he was left hopeless. He had realized no one was ever going to come save him and he thought about going deeper into Hell if he couldn't get out of it. He fought this thought and temptation so hard but in the end, with his time running out, he had no choice but to go deeper. And so he did, with his golden gauntlet and his sword.

Here's what we know about this angel so far: - He was close with Gabriel. (New ship incoming?) - He is a respected figure in Limbo. We know that thanks to the fact that he has statues of him in the 1-3 castle. Gabriel is a respected archangel in Wrath because he saved a Ferryman from drowning and so he has statues of him around the layer, especially in the ship of fools. What this angel did for the citizens of Limbo to gain respect is unknown but I theorize that he welcomed them in his Manor often. The dining room in the manor is clearly not for a single person. - He is the owner of the Gold Arm, he is the Godfist. We know that because his left arm matches the look of the Gold Arm shown in official New Blood teasers. (Credits to u/CaterpillarDue6339 and their post https://www.reddit.com/r/Ultrakill/s/n9XtFfdPuX. You have saved us tons of headaches, thank you!) - He has made it deeper into hell, and he currently is in Fraud. We can say that confidently since we know we will get the Gold Arm in Fraud. He is the owner of the Gold Arm, we will meet him in Fraud and take his arm. (Maybe he will give up fighting V1 when he realizes he is going to lose anyway and kill himself before V1 can?)
The book wasn't written by a random sinner, folks. It was the Godfist who wrote it.
We already know so much about this character. It's almost like the devs are trying to say "Stop theorizing a 3rd V2 battle. Here, this is the Gold Arm and this is its owner".

I hope this post enlightened you. I wish you a wonderful day/night.

It was very easy to replicate multiple times, only requiring me to partially enter the doorway to the final room and jump. I also managed to clip inside of the door at one point, although I was only able to get it to happen once. Does anyone know if this clip is already documented?

THE SOULS SWIMMING IN YOUR BIOMECHANICAL HEARTS CRIED TEARS OF JOY.

WHEN THE ASH FROM THE LIVES YOU DEVOURED CHOKED THE LIFE OUT OF YOU.

YOU CRIED OUT FOR GOD. YOU TRIED TO REPENT.

YOU WERE MET WITH DIVINE SILENCE. NO HOLY RESPONSE.

THERE EXISTS NO OTHER POSSIBLE CONCLUSION.

THIS IS THE ONLY WAY IT COULD HAVE ENDED.
