"Something is coming… something hungry for blood."
Bring The Upside Down and it's inhabitants directly into your Minecraft world. This mod delivers an atmospheric experience built around the lore and creatures from the show Stranger Things.
The Awakening
The Upside Down doesn't open on its own. The world starts as regular vanilla Minecraft. But when you interact with the sensory deprivation tank and encounter the Demogorgon lurking within, everything changes.
Attacking it triggers The Awakening. From that moment on, the Upside Down is alive.
Creatures from the Upside Down
| Creature | Description |
|---|---|
| Demogorgon | The apex predator of the Upside Down. Highly intelligent, incredibly aggressive. |
| Demodog | Pack hunters. They coordinate attacks and grow increasingly dangerous in numbers. |
| Demobat | Swarming aerial threats that spawn in hordes. |
| Vecna | The big bad. Haunts cursed players; stalking them, appearing and vanishing, getting deeper into your mind before it's too late... |
Vecna's Curse
Once the world awakens, Vecna may choose a victim.
- Nightmare Visions trigger randomly throughout the day - hallucination mobs, spider swarms, visions of the Upside Down, and more.
The only way out? Find your music. Use the Walkman and Kate Bush's Running Up That Hill to fight back.
Eleven's Powers
Wield the power of the most powerful girl in the world:
- Telekinesis — Levitate entities, hold them suspended in the air, then fling or blast them away with a flick of your mouse. The harder the flick, the farther they fly.
- Rift Manipulation — Focus your powers for 3 seconds to tear open a Rift to the Upside Down through any wall or floor. Focus again to seal it.
- Power Mode — Toggle enhanced power for extreme throws
- Cost — Using your powers drains hunger. Push past starvation and it costs you health.
The Upside Down Dimension
A mirrorworld version of the Overworld.
- Upside Down Dirt & Grass with unique textures.
- Rifts randomly tear open near players after The Awakening, connecting your world to the Upside Down
- Flickering lights - Upside Down interference causes nearby torches and lanterns to flicker
- Existing worlds can be synchronized with a one-time world scan when you first install the mod
Items
- Music Disc: Running Up That Hill (Kate Bush) - Your salvation against Vecna's curse. Plays in a Jukebox.
