Baldi's Basics The Ultra Decompile
SOURCE CODE FOR BBTUD IS NOW AVAILABLE!

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).
It's playable on all main platforms 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.
Is this the end of the mod?
Well, yes. Since I don't plan to make any more updates, this mod has become its final state. Don't worry, this isn't really the end. You can still download the mod itself, and chat with the community.
As of now, I still plan to update the Grand Opening schoolhouse. Therefore, it hasn't reached its end yet.
Can I submit suggestions?
Since the V3 update, I won't be adding anything else therefore I will not be taking any suggestions. NO SUGGESTIONS!
However, I plan in the future to add content to the new schoolhouse.
CAN YOU ADD-
NO. The answer will always be no. There will not be any 0.7 Plus stuff or anything else you suggest. Stop asking!
Want to see old versions?
See old versions from here, all the way up to V3.0.1 (no crashing): UPDATED!

Because it's complicated to implement.

Sorry for exposing the correct answer for the hard question
I care less lol
nice
hey swa i wanted to report a issue when ever i come back i lose all my data even null mode with cheats how do i fix it or somthing
That seems like a IndexedDB browser error, meaning that your data is just never saved because your browser or device just don't support that. I'm unaware how to fix, so please don't ask me.
you cant
In the previous version there was a regret button, but now it's gone even though I've never pressed it. You know the one in the principal's office
Oh yeah. That's because it felt very unnecessary. Especially if you don't know what the button does, it'll ruin your run and decrease your enjoyment.
man i wish i could play multiplayer but it says "your device may not support our servers" i also finished the game got the achievements i dont know what to do
is anyone there at mutiplayer?
360471
hey swa is open logs only of android or other devices
F8 if you're on computer.
Why did you delete your other replies?
i felt it was just too rude
i wanted to tell you i post your game in my youtube channel
Noobpro1513
i am on computer but chromebook i cant open logs
Have you banned access to the old versions on Google Drive?
i dont think so look at old versions
Why would I do that?
8/7 notebook Bug
That's intentional. It's to make NULL mode easier by making all notebook rooms available.
to make null mode easy i did it in hard does that me a baldi basic player?
emag eht yortsed
Challenge yourself = you considered yourself be one
in grand opening
hey seenwonderalex you said second floor 2 is in wip just saying not asking you to update
I did, but it'll probably be a long time because I'm busy with other projects.
its fine
I mean will you do update
a new update??
???
ok its probably my device or smth idk
hi swa seenwonderalex i have a question is multiplayer available on saudi arabia or windows 8.1?
I don't know if it's supported on Windows 8.1.
I listed all available regions in multiplayer, so if it's not in the list, do auto. However, finding people on public games should be USA east.
i tried aking him for windows 7 ultimate
Wait, looks like it's supported for you
Question for SWA, do you have any plans to cook more games like this?
Hey seendwonderalex i wanted to say is that when im doing the null boss fight there is no items to thorw at he was at the last shot whats wrong with it
Check the dark hallway.
why didnt i think of that thanks!
bro couldnt play i tried playing at 3am but i had ti wait for 4am
Just open logs and type scene load Starter
what is this commented out bossfight script im seeing in the source code?
Evilverse Event
Developing a mod for 5+ years gets tiring is all I'll say.
oh oka
btw I reposted the same commant again on actsent and deleted it because I saw your commant so yeah
yo alex,
is it okay if i remaster the mod?
Yeah.
Coolio
I DID IT I DID I BEAT NULL
then crashed
bro I was fighting null I needed one more hit but I lost then I have to start all over buts it alright I can try again never give up
Keep in mind you can save in NULL Style before the fight.
ok
I know that i cant write suggests but then... Can you in future add server lists. This wil be more simple to find games for my friends and other peoples. I realy like this game, i feel that you worked hard on this. Hi from all my 4 friends, well done dude
Thanks.
Hey seenwonderalex I wanted to ask you if we can play baldi ultra decompile in windows 7
No idea if this version of Unity supports that but you could check.
Hi SeenWonderAlex 🙂
Can you update it even if hard
If not can you please tell me the codes in the game
sup
he said he wont update it no more
Oh ok
I have Been waiting for someone to join for long I'm going to stop
Make sure to always play on USA East if looking for someone.
That's the default for everyone that joins a public game.
thanks
This mod is so much fun, it even looks like baldi's basics plus
