Zombie Expansion
by XxCreeperxX
Zombie Expansion adds a large set of zombie variants, weapons, blocks and dimensions to NeoForge, with a progression built around them.
What it does
Zombie Expansion brings many kinds of zombies into the game, along with four dimensions, 19 weapons and a large block set. Several structures hold lore and factions, and the progression ties them together. Some encounters summon a boss, and some zombies can adapt to boats, so trap-based tactics are harder to rely on.
A server running it needs every connecting player to have it too. Builds exist for NeoForge only, across the 1.21.1 and 1.21.4 game versions, with 1.3 for 1.21.4 as the latest file. The mod is not open source and is licensed under All rights reserved. JEI is recommended for looking up the custom recipes, and a minimap is a common aid for finding mobs in the wider world.
Key features
Many zombie types
A range of zombie variants with different behavior, some of them stronger than the standard undead and able to adapt to boats.
Undead sword line
Six tiers of the Undead Sword, each a step up in damage, with the early tiers crafted from super zombie flesh and sticks.
Fire weapons
The Fire Sword sets targets alight on hit, and the Inferno Sword fires fire charges rapidly on right click for fire damage.
Smelted flesh food
Rotten flesh can be smelted into burnt flesh, a food with lower hunger cost and better saturation than the unburnt version.
