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

2.7k 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.

Ik this sounds random and probably wrong, but I have this very strong feeling that the prophecy might be somewhat correct. It’s either im completely wrong and need to reread the whole lore, or I actually predict it

At last, I'll post it here. Inspired from u/Sela_Chopper 's work with that dying V1 in V's arms,and took the opportunity to based it over an epic classical painting, Ivan the Terrible and his son, after getting a comment about it before.
