Hammercraft40k
by Ardilos
Hammercraft40k brings the grimdark universe of Warhammer 40k into Minecraft with new creatures, characters, weapons, armor and materials for Forge 1.20.1.
What it does
The mod is a large community project created by Ardilos and a team of collaborators, including Commando315, who started it as a way to build a decent Warhammer mod after an earlier attempt fell through. Its content is split into factions. Creatures of a given faction attack and seek out enemies of other factions, so the factions fight each other across the world, and the mod is meant for players who want to take part in a fantasy roleplay setting.
Much of the design draws on Warhammer franchise games such as Boltgun, Darktide, Space Marine and Dawn of War. A neutral section covers monsters, animals and items tied to specific factions, including Necromunda monsters and Catachan creatures. The Imperial Guard has the most armors and guns, while Space Marines, Adepta Sororitas and Mechanicus content sits under the same faction. Hammercraft40k requires Geckolib and Pehkui, and Just Enough Items (JEI) is optional. It runs on client and server, so both the server and every player need it, and it is published for Forge 1.20.1 only, under the MIT License. The code is not open source.
