When The World Decays.

When The World Decays is a brutal survival horror modpack built around Scape and Run: Parasites, throwing you into a world that is actively being consumed by a hostile, evolving infection. Cities lie in ruins, civilization has collapsed, and something far worse than zombies now roams the land.

The parasites don’t just exist — they adapt.
The longer you survive, the smarter and more dangerous they become.

🧬 What Awaits You

• A decaying world filled with abandoned structures, ruined cities, and remnants of humanity

• Parasites that evolve and learn, punishing careless players

• Beacon events that summon powerful infestations and bosses

• Scarce resources that force hard survival decisions

• Exploration that feels dangerous, tense, and unrewarding if you’re unprepared

There are no safe biomes.
No peaceful nights.
No guaranteed progression.

⚔️ Survival Is Earned

You’ll need to:

• Fortify your base or stay mobile

• Choose when to fight — and when to run

• Manage fear, hunger, and limited supplies

• Prepare for escalating difficulty as the world reacts to your presence

This modpack is designed to feel oppressive, unforgiving, and alive. The parasites spread, the environment decays, and the world pushes back harder the longer you exist in it.

🩸 No Cure. No Mercy.

There is no victory screen.
There is no endgame paradise.

Only survival — for as long as you can manage it.

The only question left is simple:

What will you do when the world decays?
