Old S corp
by OLD S corp
Old S corp is a NeoForge magic and adventure mod that adds a set of weapons, from a buster sword to a bone dagger and an ocean anchor.
What it does
The mod adds 16 weapons that can be obtained in survival play, each with its own design. Among them are the Buster Sword, the Bone Dagger and the Ocean Anchor, and the weapon set is aimed at combat, including player-versus-player fights on servers.
Weapons are the main content, and the author describes the set as original and built around a clear theme rather than a list of recolored vanilla items. The mod is categorized as Magic, with Adventure and Equipment as secondary categories.
The mod runs for NeoForge on 1.21.1 only. Installation covers the server and each player's game. The latest file is 1.1.0 for 1.21.1, published 2026-01-06, and the code is under All rights reserved, so the mod is not open source.

How it compares
Extra Weapons is a NeoForge mod for 1.21.1 – 1.21.4, under the MIT License and not open source, and it is client and server. Unstoppable Weapons+ is a NeoForge mod for 1.21.1 – 1.21.9 that is server-side only, so players join without installing it. More Swords & Weapons targets only 26.1.2 and is client and server. Old S corp differs by covering 1.21.1 alone and by its bundle of 16 weapons with a single author.
