overview
The parasite infection mod adds new mobs that will infect your world and evolve. These parasites will reproduce to further spread the infection. Killing some will make it worse because other parasites may be inside.
Parasites are split up by factions. Each faction gets more powerful and dangerous and will introduce more parasite types.
How it works
It all starts when small worms called infectors begin to spawn in your world. they don't do much but if they find a villager they will infect it. The infected are dangerous and will attack other villagers. If the infected dies it will explode into smaller parasites. These parasites will further spread the infection. The rest is for you to find out.
This makes players act fast and sneaky.
