Tower Defense Mod
Tower Defense Mod turns a Minecraft Java arena into a two-team match where each side builds towers, walls and spawners to break the other's Nexus.
What it does
Two teams face off in an arena. Each team defends its Nexus by placing towers and walls and sending mobs against the enemy. Spells can be cast during the match, and the first team whose Nexus is destroyed loses the game. The mod supports multiplayer PvP, a solo mode against an AI opponent with economic bonuses, and a single-player test mode for trying builds.
The mod is a Fabric mod for Minecraft 1.21.4 only, with the latest file 1.8.0 for 1.21.4 released 2026-03-26. Installation covers the server and each player's game. The code is not open source and is covered by All rights reserved, though the source code is publicly available.
Key features
Ten tower types
Towers range from basic arrow towers to chain lightning towers and towers that deal area explosion damage.
Ten mob spawners
Spawners produce several kinds of hostile and support mobs to push into the enemy arena.
Income generators
Three generators pay passive gold over time, giving each team money to spend on towers, walls and spawners.
Five spells
Fireball, Freeze, Heal, Nexus and Lightning spells can be cast during a match to damage, slow or support.
Wall blocks
Wool, oak and cobblestone walls form four-block pillars, and the fireball-resistant walls stop incoming fire.
