Undead Armies

by itsjeff

Undead Armies makes undead mobs cooperate, so groups of them can work together to destroy a player or another entity such as an iron golem.

What it does

Undead mobs in the mod coordinate with one another and with other entities to reach a chosen target, which gives the groups a more deliberate approach than default undead behavior. Undead mobs can also help destroy targets alongside other mobs in the world.

The mod runs on the server, so players join without installing it. It is open source under the GNU General Public License v3.0 only, and files cover 1.21 – 1.21.5, with 1.6.0 for 1.21.5 as the latest NeoForge build. Source code, an issue tracker and a wiki are linked from the project.

Key features

  1. Cooperating undead groups

    Undead mobs coordinate their movement so that several of them can pursue the same target together.

  2. Targets beyond the player

    Undead groups can also go after other entities, such as iron golems, not only the player.

  3. Ramming and trampling

    Some undead attack by ramming and trampling their targets, a behavior the author renamed and is still reworking.

  4. Stacking and block breaking

    Mobs can stack on one another and break blocks in their path, with their progress stored on the server.

What the author says

Have you ever felt the undead mobs in minecraft were lacking intelligence? This mod fixes that! this mod enables undead mobs to work together to destroy a player or any other entity [such as iron golems]. Undead mobs can also do other things that help them destroy their targets.
