Krex's Stranger Things

Step into the Upside Down

WARNING: This mod contains spoilers for Stranger Things. Please support the official show on Netflix!

Fan-made and not affiliated with Netflix or the creators of Stranger Things. Inspired by Prim's Stranger Things Mod, thank you Prim!

Welcome to Krex's Stranger Things!

Venture into the Upside Down and brave its horrors. Open gates, mirror your world into a dead, spore-filled twin dimension and survive what lives there.

Content

Step through a gate and see what's waiting on the other side.

The Upside Down is a dead twin of your world: no water, no flowers, bare trees, spores in the air and a storm that never stops. Red lightning crawls through the clouds, and only its own creatures live there.

Gates tear open in the world. Press against one to break the membrane (with Immersive Portals you can see through it and just walk in).

What lives there:

  • Demogorgons, Demodogs and Demobats
  • Dart, a little creature you can raise (and tame with nougat)
  • The Mind Flayer, a giant shadow that rises in the storm and watches you

Places to find:

  • Hawkins Lab, with the Gate hidden in the basement
  • The Nevada mine and Henry's stone

Plus a flashlight, a nail bat, a slingshot, a flamethrower, walkie-talkies, hazmat suits and more.

More coming soon.

Requirements

  • Minecraft 1.20.1, Fabric, Fabric API, GeckoLib
  • Optional: Immersive Portals, Sodium + Indium, Cloth Config

Credits

Thank you to Prim for the original Upside Down Mod, which inspired this one.
