Superflat Plus
Superflat Plus gives players a flat world with an added layer of structures, lucky blocks and mob spawning, and it is aimed at Forge players on the Minecraft versions in the 1.20.1 – 1.20.6 range.
What it does
The mod adds two new world types built on the superflat layout. A superflat world is a flat terrain that can carry structures, adjusted density and lucky block generation, and the author notes that it supports structures spawning in the superflat world, lucky blocks in both superflat and normal flat worlds, and nether and end mobs spawning in the superflat world. One of the new world types is an Air Life world, which is listed as being in beta and still under development.
The server and every player need the mod installed. Files are published for Forge only, across six game versions: 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5 and 1.20.6, with 1.0 for 1.20.6 as the latest file from 2026-04-12. The mod is released under All rights reserved and is not open source.
