Altered (discontinued)
by Axolotl1
Altered adds a new dimension for NeoForge on 1.21.4 that looks like the overworld but feels wrong, with scattered anomalies and portals that lead to it.
What it does
Players who enter the dimension are warned that it is much easier to get in than to get out. Its terrain resembles the overworld, yet nearly everything looks and feels off, and some things appear that should not yet exist. Traces of someone who vanished long ago can be found through depleted machines. Altered works through an unstable crystal that bends the space around it, and a portal generator must be supplied with that crystal before it can open a gateway into another reality. The mod runs on client and server, so both the server and every player need it, and it targets NeoForge for 1.21.4 only, with the latest file dated 2025-07-31 on the beta channel.
