Mustard Virus Addon is a highly popular Bedrock Edition addon that transforms the game into an intense zombie apocalypse survival experience. A deadly virus spreads, mutating zombies and mobs over time, forcing players to scavenge, craft advanced “Spartan” weapons, and fortify bases against increasingly aggressive hordes.
Features:
Weapons
- 18 tiers of “Spartan” weapons (e.g., Wooden, Netherite) across materials like Titanium, Platinum, and Electrum. Apocalypse-grade tools for combat.
Zombies & Mutations
- Normal zombies (day 1, evolve speed/damage).
- Crawlers (crawl under blocks).
- Armored (netherite gear, day 70+).
- TNT/Block Miner/Building/Teleporting Zombies (day 60-100+).
- Giant Mutations.
- Players turn into zombies on death (200+ skins).
- Nether: Piglins mutate too.
Events & Mechanics
- BloodMoon: Intense night event.
- Mob dismemberment.
- Hordes, survivors/bandits (drop ingots, wear chem suits).
- Boards/spikes/traps for bases (zombies break boards after day 40).
