    About

    The Backrooms Ultimate Edition brings explorable Backrooms environments to Minecraft, drawing its levels, entrances, and exits from the Backrooms Wiki. It includes Level 0, Level 0.2, and Levels 1 through 6, with locations such as the Tutorial Level, Remodeled Mess, Habitable Zone, Pipe Dreams, Electrical Station, Abandoned Office, Terror Hotel, and Lights Out. In Survival mode, players can enter the Backrooms by getting stuck in sand or gravel, and the /tplevel command provides a way to teleport between levels. The mod currently has no custom mobs or entities, so exploration focuses on the environments themselves.

    Security

    Not checked yet

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12 to 1.12.2.

    Its author does not let other sites download its files from CurseForge, so we cannot check them.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · Not checked yet
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      1 latest file. It is not for a recent Minecraft version, so the answer above is about it. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases

    Privacy

    We have not read its code yet

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12 to 1.12.2.

    What it sends is not known yet.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · Code not read yet
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      None yet. See each file in Releases

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its description and code history and found none.

    We have not read its changelogs, files, images and sounds yet.

    AI in the game: not checked yet

    We have not read its code for AI yet.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
