BloodInfection999
by ShadowClan
BloodInfection999 turns a world corrupted by a blood infection, where once-peaceful creatures become carriers that spread the infection through contact.
What it does
Players explore a world where a blood infection has spread through its animals and villagers, and every infected creature threatens survival. Infection spreads through contact and through infected blocks, which slowly corrupt nearby terrain and turn it into dangerous zones. The spread speed is configurable.
Infected versions of chickens, pigs, sheep, cows, villagers and bunnies each use their own combat style, from fast charging poultry to evasive bunnies. After a infected creature kills five victims, it changes into a more dangerous Phase 2 form, and certain Phase 2 forms turn into fixed spawners that summon infected mobs at intervals.
The mod requires Geckolib, and Mod Menu is optional. The server and every player need the mod installed. Files are published for Fabric and Forge, with the latest Fabric file for 1.21.11 and the latest Forge file for 1.20.6. The mod is All rights reserved and is not open source.
