AlienMod

by mudkipboy7

AlienMod lets players travel from the overworld to a distant alien planet, reached through a Blue Planetary Key found in dungeon chests.

ForgeClient and serverAll rights reserved1.20.1 – 1.20.6

What it does

To reach the alien planet, a player must first locate a dungeon underground and search its rooms for chests. The chests at the bottom of the dungeon usually hold the Blue Planetary Key, the item needed to travel there. Once there, the planet offers animals, plants and mechanics that differ from the overworld.

The alien planet has its own sky and lighting. Its sun gives off a redder, darker light than the overworld, so the surface looks moodier and more visible in certain conditions. A companion planet sometimes eclipses the sun, and during those eclipses monsters can spawn. The planet also has lower gravity, letting the player jump about one and a half times higher than on the overworld.

AlienMod runs on Forge and is published for 1.20.1 – 1.20.6, with 1.20.1-3.1 for 1.20.1 as the latest file. It is client and server, so both the server and every player need it. The code is not open source and is released under All rights reserved.

Key features

  1. Alien planet travel

    A key item opens the way to a separate planet that sits apart from the overworld.

  2. Altered sky and lighting

    The planet has a redder, darker sun and different skies, which change how the surface looks.

  3. Companion planet eclipses

    Eclipses by a companion planet can make monsters spawn on the alien surface.

  4. Reduced gravity

    Lower gravity lets the player jump about one and a half times higher than in the overworld.
