🧟 Lost Hope: Zombie Apocalypse Survival (Multiplayer Modpack)

Version: 1.20.1
Focus: Multiplayer | Survival | Hardcore | Apocalypse

Step into the ruins of a forgotten world 

where cities lie in decay, resources are scarce, and the dead never sleep. Lost Hope is a brutal zombie apocalypse survival modpack, built around multiplayer cooperation (or betrayal), immersive survival mechanics, and terrifying undead.

🔥 Core Mods:

  • Lost Cities – Explore vast, abandoned urban landscapes filled with loot, danger, and dark secrets.

  • Tough As Nails – Survival just got real. Battle against thirst, body temperature, and unforgiving environments.

  • Zombie Awareness – The dead can hear your every move. Light, sound, and blood attract smarter, faster, and more persistent zombies.

🧱 Key Features:

  • 🧟‍♂️ Advanced Zombie AI: They're faster. They're smarter. They're organized. Hordes will track you for miles.

  • 🏙️ Urban Survival: Scavenge high-risk, high-reward locations in collapsed buildings, subway tunnels, and infected streets.

  • 🌡️ Hardcore Environment: 

  • Manage body heat, thirst, and exhaustion. Seasons and weather matter.

  • 🔧 Weapon Crafting: Arm yourself with everything from bats to shotguns. Defense is survival.

  • 🧰 Base Fortification: Reinforce structures, place traps, and build strongholds to survive nightly hordes.

  • 🤝 Multiplayer Oriented: Perfectly balanced for co-op survival, PvP skirmishes, or roleplay.

  • 📜 Optional Quests & Goals: Community challenges and world events keep things interesting long-term.

✅ Recommended Specs:

  • 4–6GB RAM allocated

  • Built-in performance optimization (e.g. Sodium)

  • Includes voice chat mod for team immersion

The cities are dead. The world is colder. The undead are hunting. Can you and your friends survive the fall of civilization?
