Bacterium

by RemyEliot

Bacterium lets players handle dangerous bacterial samples in a lab-themed Fabric mod, with items that carry risks if mishandled.

FabricClient and serverCustom license1.21.11

What it does

Bacterium adds bacteria items that players can collect and work with, and the author describes the samples as dangerous enough to destroy the world. The mod is built around a chemistry-lab theme, with scientist-style gameplay that skips a long academic path. Installation needs Fabric API, and the mod runs on Fabric for 1.21.11 only, as a Client and server mod, so the server and every player need it.

Several item types are tied to the sample theme, including blue and red bacteria, a welcome crew group, and a penalty that triggers when a sample is dropped on the ground. Sample items also show color-coded tooltips. The mod is released under a custom license and is not open source, though its source code and issue tracker are public.

Key features

  1. Blue and red bacteria

    Two bacteria types are added as sample items, each with its own in-game description and handling.

  2. Butterfinger penalty

    Dropping a sample on the ground triggers a penalty, meant to discourage carelessly handling the items.

  3. Color-coded tooltips

    Sample items show tooltips colored by their bacteria type, so their hazard level is visible at a glance.

  4. Welcome crew

    A welcome crew group is included as part of the mod's lab-themed content.
