So, the true ending hasn't been found in Roblox, piggy. So I've decided to organize a search. You can either post methods you've tried here, (Even if they don't work so that no one wastes their time) so just or comment them in our Studio: https://scratch.mit.edu/studios/26757694/projects/
I'll leave the list on the Studio (because it's quicker to edit)
I know we can do, it, even if it takes us days
If we can't find in in the next few days, I might buy us a private server, so that we can test their, so we aren't getting in the way of other players
I'll update this post if we ever find it, and tell you guys how to get it. Same for the studio
My roblox username is DR_Trove
What are you waiting for, GET SEEKING! (if you can, or searching, if you prefer that)

UPDATE: The true ending has been found!
How to get it:
Select Chapter 9 (city)
Select player and bot (so yah, it needs to be multiplayer
Complete the chapter but DON'T exit.
Go find one of the purple around the map and grab the ms. P. picture
Beat the chapter
Beat chapter 12
get the BAD ENDING
Boom.
