Baldi's Basics The Ultra Decompile

A Baldi's Basics Mod, the original game here.

What is this decompile?

This decompile is a place with a lot of content built into the classic version of Baldi's Basics. It's like playing classic but with all of the new content around (remaining its classic style).

WHERE CAN YOU PLAY IT? Every main desktop platform and even Android! Heck, you can even play in your browser!

What kinds of content are inside?

• A second or third floor. An elevator system.

• Adjustments you can make to spice things up.

• MULTIPLAYER! Competitive (playing as Baldi) and Cooperative (beating Baldi with other players).

• Carryovers from other Baldi's Basics games (BIRTHDAY BASH!, Camping Field Trips, etc.)

• Fresh new modes (Hide & Seek with Baldi and Multiplayer).

• Play between two schoolhouses (Classic and Grand Opening).

• 7 Unique items.

• 10 endings (Classic and Grand Opening).

• Unique and improved mechanics.

• And a lot more!

Feel free to learn more. There's a bunch of content waiting for you in this mod.

DISCLAIMER: This decompile has tons of features that separate itself from Plus. It's never intended to be the original game. Although it does have Plus items and characters, it's built through Classic with legal functions, and no core features are implemented. If there's any concern or anything not allowed in this decompile, please reach out and I'll comply.

Download Source Code

This mod is now officially open-sourced! You can download the source code of Baldi's Basics The Ultra Decompile here. Read this post for info.

Is this the end of the mod?

Well, technically yes. This mod has been in development for five years, and a lot has changed throughout time. Due to my demotivation, it's best to leave this game in its current state. Remember, the source code is available above if you want to continue yourself. Don't worry, you can still download the mod and chat with the community.

As of now, I still plan to update the Grand Opening schoolhouse. However, there won't be anything new until like 2026, when I'll get motivated to finish that again.

Want to see old versions?

Here's an archive of every version that I (or the community) had saved.

All the way from V1.0 to V3.0.4 (Windows & Android). Some versions were skipped as I didn't have the files. Do not worry about V1.4's crashing issue, as that has been resolved.
