About this Mod

Mod Features

"It’s a plane out of phase, a world of monsters. It is right next to you and you don’t even see it." -Scott Clarke

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, creepy vines cover the walls and floors, dead particles float around.

Act quickly, because once you are in the Upside Down, the demogorgon is coming. And if it catches you, there is little chance of escape.

Shooting the Demogorgon

Your only hope is to find the nearby "gate" that the Demogorgon opened to get into your world. If you find it, you can pass through it to escape the Upside Down.
