Stranger Things

by SwirlyOnYouTube

Stranger Things adds a Fabric mod for Minecraft 1.21.1 that brings the Upside Down and its creatures into a regular vanilla world.

FabricClient and serverAll rights reserved1.21.1

What it does

The mod opens as a normal survival world. The Upside Down does not open on its own; it is reached after an Awakening, which is triggered when a player attacks. Once the world awakens, Vecna chooses a victim, and rifts begin to tear open randomly near players, connecting the overworld to a mirrorworld version of it. Dirt and grass in that dimension carry unique textures, and Upside Down interference makes nearby torches and lanterns flicker. Gameplay centers on powers. Telekinesis lets a player lift entities, hold them in midair, and fling them away with a flick of the mouse, with a harder flick sending them farther.

Creatures and atmosphere come from the series: Nightmare Visions trigger at random during the day, and hallucination mobs, spider swarms and visions appear in the Upside Down. A sensory deprivation tank lets players encounter the Demogorgon, which lurks within everything once the dimension is alive. Players can also find a Walkman and use Kate Bush's Running Up Hill to fight back.

The mod is published for Fabric only, and it runs on both client and server, so the server and every player need it. Fabric API, Geckolib and Sodium are required, and Immersive Portals is optional. All rights reserved applies, and the code is not open source.

Key features

  1. Random Nightmare Visions

    Nightmare Visions trigger at random throughout the day, adding unexpected scenes to ordinary play.

  2. Telekinesis

    Players lift entities, hold them midair and fling them away, with a harder flick sending them farther.

  3. Rift Manipulation

    A Focus powers a three-second rift through walls or floors into the Upside Down, and using it again seals the tear.

  4. Upside Down dimension

    A mirrorworld version of the overworld with unique dirt and grass textures, reached through rifts that open after an Awakening.

  5. Hunger and health costs

    Using powers drains hunger, and pushing past starvation costs health, so every power has a physical price.

Questions

Does Stranger Things need Fabric API?

Yes. Fabric API is required, along with Geckolib and Sodium. Immersive Portals is optional.

It does not open on its own. An Awakening is triggered when a player attacks, after which rifts tear open randomly near players.
