Stranger Things

This mod introduces the Upside Down dimension and new enemies, bringing a new layer of tension to exploration and survival.

The Upside Down

Description

Access

Players can enter the Upside Down through portals that appear with the Demogorgon’s arrival.

Environment

Crossing over dramatically alters the world:

  • A blue mist affects the atmosphere.
  • Spores are floating in the air.
  • All lights instantly shut off, including inside the ship.
  • The ship becomes fully disabled (no interactions or functionality).

Outside the Dungeon

  • A red thunderstorm rages permanently (functions like Stormy).
  • Trees are lifeless.
  • Bats are flitting above the ship.

Hazards

Bat Hordes:

  • Hordes of bats roam the Upside Down.
  • Coming into contact with them strike fear into the players.

Vines:

  • Organic vines spread across the environment.
  • Coming into contact with them reveal the player's location.

Audio

  • Players inside the Upside Down can hear players in the normal world at reduced volume.
  • Players in the normal world cannot hear anyone inside the Upside Down.

Visibility Rules

Players, monsters, items and configurable game objects are only visible if the player is in the same dimension.

  • What exists in one world may be invisible in the other
  • …until you cross over.

Scraps

New Stranger Things-related scraps can be found in the Upside Down:

  • Steve's Bat
  • Jonathan's Camera
  • Fairy Lights
  • Eddie's Guitar
  • Starcourt Sign
  • Waffles Box
  • Old Walkie-Talkie

Light Interaction

  • When a player in the Upside Down gets close to a dungeon light or a flashlight, the light starts flickering.
  • This can be used as a communication tool between players in different dimensions.

Antenna System

  • By default, walkie-talkie communication from the Upside Down is disabled.
  • Antennas can be purchased from the shop.
  • Antennas can only be placed in the normal world.
  • Players located in the Upside Down can only hear and speak through walkie-talkies if they are close to an antenna.
  • Players in the normal world do not need to be near an antenna to communicate.
  • Antennas have a battery that can be recharged in the ship.
  • Antennas can be used as melee weapons, but any strong impact destroys them.
  • Antennas deal 3 damage.

Mirrored Items

  • Copies of items that spawned at the start of the day also appear in the Upside Down.
  • When picking up a mirrored item, particles appear around it.
  • These particles become more intense as the player gets closer to its counterpart in the normal world.
  • Particle colors indicate distance:
  • Blue = very far
  • Purple = medium distance
  • Red = very close
  • Once close enough, the Upside Down player can target the normal-world item, but only if it is currently carried by another player.
  • When the target becomes valid, the normal-world item’s aura becomes visible.
  • Using the mirrored item consumes it and multiplies the value of the normal-world item by 3.

Vecna

Description

Vecna is the main enemy, he is a more narrative enemy and appears in several forms (only the first one is currently in the game).

Part 1 - Henry Creel

Description

A powerful telekinetic enemy that relentlessly hunts players in the normal world, using the environment itself as a weapon.

  • Spawns indoors and in the normal world only.
  • Cannot enter the Upside Down in this form.
  • Moves slowly, but compensates with devastating telekinetic abilities.
  • If players get too close, Henry can perform moderate melee attacks.

Telekinetic Attacks

Indoor

  • Henry can telekinetically lift 3 small pebbles from around the targeted player.
  • This ability does not require direct line of sight.
  • The pebbles are launched one

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Dependencies

Install these first, or the mod will not work:
