Hi! So, I had no clue how few maps there are of the game "changed". And the few that do exist are either half-finished or/and abandoned, so why not make one myself?

I started it alone, then with the slight help of a handful of people, including C0_des (I recommend checking their map out), we had finished it.

Huge thanks to MercurialRainInPastels for helping me port it to 1.20.1!!!

Updates may come whenever I feel like working on the map, such as actually doing lore bits. Perhaps a ruin version of the map.

(Please do not reupload this map anywhere.)
(If you use this map anywhere, please credit me. I put in so much effort into making this.)




Necessary Mods (1.18.2/1.20.1):
  • Changed
  • Changed addon plus
  • Immersive engineering

Optional but personally recommended: Changed armor and weapons (For roleplay and so on.)



Shader used:
  • Complimentary reimagined
  • low brightness recommended

Final update? : by BreadKenyer 07/16/2026 3:08:37 pmJuly 16 @ 7:08 pm UTC

Finally finished this map. Was it fun? Yeah, sort of. Will I probably update it in the future? possibly.

Until then, have fun!

It would be cool to have a version of the map where it takes place after the riot.
Could include pillows for the dark latex too

Nice map

Love the aquatic area and the claustrophobic hallways/chambers. Good job!

I dont exactly know how to do that, sorry. Maybe just try to open it in 1.20.1 with the same mods?

unfortunately, the mods have changed too much. I'd have to rebuild the whole facility if I port it to 1.20.1. Sorry.
