⬇ Download on CurseForge



The Cordyceps fungus has evolved to not only take over insects, but other living beings too. Our civilization is now slowly vanishing and being taken over by the infection.
We cannot stop it, the real question is: how long can you survive?
A world taken over.
You will coexist along the Fungal Infection, it has been evolving, and will keep doing so. It's only a matter of time until it becomes a real issue for you. You must prepare your defenses.

Guides to Survival.
Find the lost books written by a legendary survivor called Steve. These book-like questlines will guide you through defending your base and preparing for the worst.

Upgrading Defenses.
Start from primitive defenses such as spikes, evolving up to slingshots, cannons, and even turrets. Follow the Dragon Association and develop the ultimate bio-weapon against the infection.

Perfect for Co-Op & Low end PCs
This modpack is very lightweight and can run on pretty much a toaster. It's also perfect for Co-Op and doesn't require too much ram on the server to run well (6gb recommended for 4 players).
