# ~~`the_backrooms`~~ > *If you're not careful and you noclip out of reality in the wrong areas, you'll end up in the Backrooms* I set off some AI agents to explore how to write level generation plugins. After a few days, I came back to this. They did things I didn't ask for. There's levels and levels, and some of the levels have... things in them. The agents say there is a way to escape, but I don't believe them. !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/lobby-shaders.png) | | | | |---|---|---| | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/lobby.png) | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/habitable.png) | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/pipeworks.png) | | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/poolrooms.png) | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/disc_11.png) | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/library.png) | | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/corrupted.png) | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/poolrooms-2.png) | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/far.png) | | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/glowstone.png) | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/gold.png) | !(https://raw.githubusercontent.com/def9a2a4/backrooms/refs/heads/main/docs/assets/twilight.png) | --- # Plugin Info (warning: spoilers) This is an in-development survival horror plugin inspired by the (https://en.wikipedia.org/wiki/The_Backrooms) and minecraft "lore".
