THIS IS THE LEGACY VERSION OF THE MAP. If you want the best experience, please download our most recent upload linked above. This is just for those who either have an older device that can only run 1.21.11, or curious to see the legacy version of our map.

Cochlea is a fully vanilla Minecraft (single-player/multi-player) liminal spaces map. In the game, you are an expendable, located at prison site [​REDACTED]. All you currently know is that you'll be sent into the backrooms to find out what happened to the other scientists and expendables after they lost radio contact upon venturing into the backrooms.

This game takes about 3 hours to complete, and has 12 unique levels that you can explore; involving dialogue, lore, entities, jukeboxes, and lots of easter eggs. The project was a joint effort between PooPooPunisher and McChunky, taking 350 hours combined to complete (and 13,154 command block interactions).

The latest version you can play this game is Minecraft version 1.21.11, because of the recent /gamerule syntax changes and blocks. This game has absolutely 0 mods. We hope you enjoy our project that we worked very hard on, go explore and try to survive expendables! :D

You're actually supposed to walk down the main hall and take a right once you pass the cafeteria. We're putting in a direction text for when you enter the map. Thanks for your input, this has made our game better to navigate! The update will be out soon



Update: We've posted the new version of this game, you can re-download it to play again
