Adds a creature that will stalk you and progressively become more aggressive. Not exactly a dweller.

The Anomaly Anomaly (Release 2.0.0b30.1) targets 1.19.2 with Forge. The project page does not say whether this file belongs on the client, dedicated server, or both. All 1 required mods have matching files.

Install GeckoLib first. We found matching files for this game-version and loader setup.

About this project
What does The Anomaly add?

Warning! You need GeckoLib for the mod to work properly!
Official Discord Server made by MangoTree30!
This mod was made after the Mimicer, it is not a copy tho, and sorry for the confusion
2.0 Currently on BETA
The Anomaly is the new entity added by the mod, this entity seems to reside mostly in the caves, tormenting anyone who delves deep into them. Stay awake or it might evolve over time. For those who have played this mod before, the anomaly might have changed slightly it's behaviour.
The mod is meant for long playthroughs, you will not encounter the entity during the first days, make sure to make the most of it.
The mod is meant to be played without much more knowledge about the entity. I won't respond to most questions about the entity's behavior.
I also recommend checking the versions changelogs. You might find some important info about the mod, not too much tho.
Sounds were made by Mazellmi and SCP Containment Breach (Sorry! I had totally forgotten!)
Don't forget to use the lastest mod's version!

This mod hasn't been fully tested in multiplayer, feedback is appreciated!
