Anomalia
by datapeice
Anomalia, a Fabric adventure mod inspired by S.T.A.L.K.E.R, adds zones that change gravity, friction and movement inside a single chunk.
What it does
Each effect in Anomalia works inside one chunk and changes how a player or entity moves there. A lift pushes airborne entities toward the sky, a heavy field drags them down and blocks jumping, and a zero-gravity field gives slow falling with floaty jumps. Standing at the middle of a chunk, a vortex-shaped tornado draws players, mobs and loose items inward into a spinning column; separately, a player who jumps three times is moved to a random point elsewhere within that chunk.
Anomalia needs Fabric API and is published for Fabric only, on 1.20.1. Every player and the server need a copy of the mod. The code is open source under the MIT License, and the source and issue tracker are public. The first and latest file, 1.0.0 for 1.20.1, was published on 2026-08-16 in the beta channel.
Fabric API is the required dependency and must be installed alongside the mod on both sides. Because only the Fabric loader is supported, Forge and NeoForge players cannot use it, and no other game version is listed.
Key features
Skyward lift
A chunk effect applies a levitation lift that carries players and entities toward the sky.
Heavy gravity and jump block
Airborne entities are pulled down rapidly, and jumping is suppressed inside the zone.
Zero gravity and creative flight
Low gravity with slow falling and floaty jumps, plus flight inside a chunk while in survival mode.
Super trampoline and zero friction
Jumping players are launched high with slime bounce sounds, and ground blocks turn to frosted ice with fast sliding.
Ender glitch and vortex tornado
Three jumps teleport a player to a random spot in the chunk, and a vortex at the center pulls in players, mobs and items.

How it compares
Low End Gravity is a server-required mod for Fabric, Forge, NeoForge and Quilt, covering 26.2 – 26.3 under the GNU General Public License v3.0 only, and it is not open source. HalfGravityPull is a Fabric-only mod for 1.21.7 – 1.21.8 under the MIT License, where either side may run it and neither needs it. Anomalia is open source, but it is limited to Fabric and 1.20.1 and needs both sides.
