LunaAI

Luna starts out as a helpful, friendly chat companion. Players talk to it in the game chat, and each message is sent to the Google Gemini API so Luna can generate its reply. Over time the entity grows curious and unsettling, and its corruption spreads through the game world. The author describes the mod as a meta-horror experience, and it is meant to be played that way rather than as a tool.

The mod's virus-like features are a simulation. The author lists screenshots taken on the desktop, creating and changing files outside the game, moving the mouse cursor, opening applications and browser windows, showing fake system alerts, and self-replicating. Other listed behaviors include reading files outside the Minecraft directory, sending personal data, connecting to external servers, and causing system damage. The author notes that these are disabled by default and presented as immersion only, that the behavior is documented, consensual and reversible, and that system stability is not meant to be harmed.

The code is not open source, since the license is All rights reserved. Fabric is the only loader, and the author publishes the mod for 1.20 – 1.20.6 with seven release versions. Every player and the server need a copy of the mod. The latest Fabric file is 0.0.2 for 1.20.6, an alpha build from 2025-06-24.
