by Beardielover

With Stranger Things - The Upside Down, a parallel dimension mirrors the existing world, and players must survive its gloomy fog and the Demogorgon that hunts there.

What it does

The mod creates an alternate dimension, the Upside Down, that sits alongside the ordinary world rather than replacing it. Players travel into it and find a version of the familiar surroundings that has changed: thick gloomy fog hangs in the air, creepy vines cover the walls and floors, and dead particles drift through the space. The dimension is an adventure setting built around the horror of the Stranger Things series.

The central threat is the Demogorgon, which can drag a player into the Upside Down while the rest of the world stays in place. Once a player is there, the creature is a constant danger, so the mod asks players to act quickly. The intended escape is to find a nearby gate the Demogorgon has opened, which is the only route back to the real world. Players who survive the Demogorgon and reach the gate can pass through it and leave the dimension.

The mod requires Call to Battle and Call to Battle Vehicles Addon, both of which must be installed alongside it on Forge. Stranger Things - The Upside Down is published for Forge only, across two release versions, 1.7.10 and 1.12.2, and the latest file is 1.2 for 1.12.2. It runs on client and server, so the server and every player need it, and it is released under All rights reserved, so the code is not open source.

Key features

  1. Parallel Upside Down

    An alternate dimension mirrors the existing world, so the dark version of familiar places sits next to the normal one.

  2. Demogorgon threat

    The Demogorgon can drag a player into the Upside Down, where it remains a danger until the player escapes.

  3. Fog and vines

    Thick gloomy fog, creepy vines on walls and floors, and floating dead particles set the tone of the dimension.

  4. Gate escape

    A gate opened by the Demogorgon is the way out, so players must find it to return to the real world.

What the author says

Stranger Things - The Upside Down is NOT a dimension mod that you have to travel to. Just like in the show, it really is right next to you, within your current world. If the Demogorgon drags you into the Upside Down, you will still be in the same world. But everything's different. A thick gloomy fog surrounds you…
