SCP: Shadow Base
by cyz00549
SCP: Shadow Base is a NeoForge decoration mod for 1.21.1 that adds facility-themed blocks and items to Minecraft.
What it does
The mod's content draws on the SCP Foundation setting and on similar projects such as SCP: Containment Breach. Its blocks and items are built around a base-style facility look, which gives builders a set of pieces for constructing a secured complex inside a world.
The mod is published for NeoForge only, with a single game version, 1.21.1. Its files are a development and testing build, and the author states that work on 1.21.1 is progressing slowly. The mod runs on client and server, so the server and every player need it, and it is released under All rights reserved, so it is not open source. Pairing it with other mods is said to add to the experience.
