The wasteland doesnt forgive. Scavenger convoys roam the dust, armed factions gun each other down over scrap, and something under your skin is starting to change. Pick your class, watch the horde-portals crack open, and pray the supply plane finds you before the parasites do.
📋 Full Description
Wasteland Decay is a hardcore survival modpack built around three main threats: parasites, radiation and scarcity
🦠 Redesigned Parasite Evolution
Parasites evolve every single day. From Day 0 to Day 100, the danger slowly grows. It starts easy, but later it becomes brutally hard
🌀 Horde System via Portals
Dangerous portals open across the wasteland. Regular hordes of monsters will spill out of them
🏰 Tower Defense
If you survive the early days, you get the tools to fight back. Build turrets, set deadly traps, and craft reinforced blocks. Follow the full in-game guidebook to design your shelter
🚚 Living Wasteland - NPCs & Factions
• Survivor Traders: Small traders spawn all over the map. They are just trying to live in this dead world • Three-Way War: Armed factions spawn dynamically. They hate parasites, but they can also turn on each other—and on you. The wasteland is a warzone with or without you
✈️ Vehicles via Create Aeronautics
Cars, trucks, helicopters, and planes are woven directly into wasteland generation using Create Aeronautics. Significant work went into making every vehicle survival-friendly, featuring fully functional refueling mechanics and a realistic road network
🎯 4 Specialized Kit Starts
Choose your role from day one - Commando, Engineer, Paramedic, or Support. Each with its own gear and playstyle (yes, the class lineup should feel familiar to fans of a certain co-op horde shooters)
🗺️ Custom Wasteland Generation
An entirely distinct world generation from vanilla overworld - structures, terrain, and biomes hand-picked and tuned specifically for the wasteland setting.
📦 Supply Drop System
Call in air support with supply crates: Ammo, Medkit, Weapon, and Common crates, each drawing you out into the open to secure the drop.
🌡️ Survival Systems
Thirst, hunger, diet, cold, and a classic hardcore-realism death/respawn loop stack on top of extreme heat and radiation zones - every resource matters, every trip outside is a risk.
