Description
Fast Zombies Extended
Survive 100 days of escalating zombie horror. Build. Craft. Fight. Die. Repeat.

Welcome to the Apocalypse
Fast Zombies Extended is a comprehensive zombie survival experience built for Minecraft 1.12.2. Every night, the undead grow stronger, learning to dig through your walls, build bridges to reach you, and rain from the sky in waves. Armed with modern firearms, advanced machinery, and fortified defenses, you and your friends must survive 100 brutal days culminating in an epic final battle.
What Makes This Different?
🧟 Evolving Zombie Intelligence
Zombies aren't just faster or stronger; they gain entirely new abilities as time passes. What starts as a standard survival challenge becomes a desperate war of attrition.
Days 0–2: Peaceful start, no spawns
Days 3–34: Standard survival, build your empire
Day 35: Zombies learn to dig through walls
Day 50: Digging speed increases
Day 60: Full-speed destruction
Day 70: Zombies build pillars to climb
Day 80: Haste + 10% carry TNT
Day 90: Haste II + 25% carry TNT
Day 99: Final Invasion + Apocalypse Lord boss
Day 100: Victory
🎮 Multiple Map Templates Included
Choose your battlefield. The modpack ships with several pre-configured world templates, each offering a completely different survival experience. Whether you want urban warfare, island isolation, or classic survival, there's a map for you.

🔫 Modern Combat
Guns aren't optional; they're survival. The modpack is built around Modern Warfare Cubed, giving you access to pistols, rifles, shotguns, LMGs, and rocket launchers. Set up ammo production lines, craft magazines, and never run dry when the horde arrives.
🏭 Deep Tech Tree
Progress through Mekanism for advanced alloys, energy storage, and reinforced materials. Master Immersive Engineering for industrial-scale ammo production and automated defenses. Your technology is your lifeline.
🏰 Base Defense
Build smarter, not harder. SecurityCraft provides reinforced blocks, alarms, sentry turrets, mines, and laser grids. But be warned, the best materials require genuine tech progression. No cheap invincibility.
🌙 Atmospheric Horror
Blood Moons bring maximum spawn rates and zero light protection. Enhanced visuals, hardcore darkness, and dynamic fog make every night feel like a horror movie.
🩸 Final Boss
Day 99 brings the Apocalypse Lord, a custom boss with scaling HP, block-breaking aura, lightning powers, and relentless pursuit. Defeat it to win the modpack.
Tips for New Survivors
- Days 3-34: Focus on technology. Guns, machines, power.
- Day 35+: Your walls are no longer safe. Upgrade everything.
- Day 70+: Ceilings are mandatory. They will climb.
- Day 99: Focus fire the boss. Killing it ends everything instantly.
- Play with friends. Solo survival past day 70 is extremely difficult.
- Hard difficulty recommended for the full experience.
