Destruction! Awesome bacteria colonies in your world! You can play with them, let them eat the hole world!
Or just parts of it! You can also make new genetically changed Bacteria colonies which don't just eat blocks!

The big world of Bacteria is opened for you! Play with them! Let them spread! Kill them!

HOW TO:
Beginning:
Search some sponges in rivers, lakes or in the ocean, or craft them if you don't want to search! Then craft some Must, place it under water, and let it grow. The Must grows only if water's above them, example in the Video! If the Must is grown(lighter green), you can harvest it! If the must is not fully grown, it will just drop the Must block. If it is grown you get some Bunch of Bacteria. Then craft some bacteria colonies!

Bacteria:
Bacteria can be "tamed" to eat a special type of block like dirt, stone, water, lava, etc. You just have to place a bacterium colony, place all types of blocks you want it to eat directly above it (grass and dirt are the same, you don't have to place both) and finally power it by redstone or just place a redstone torch/block next to it! You will see it spread! (All spreading Bacteria blocks are of one colony!)

Replacer:
Will automatically set the block type below as food and will replace it with the block type above!
To start, just power it with redstone!

Jammer (item):
The Jammer item is a remote control which sends a jamming signal to ALL bacteria colonies in the world!

Jammer (block):
You can place a Jammer wherever you want the bacteria to stop. If the Bacteria reaches it, all Bacteria blocks of that colony will die! (Other colonies will continue to spread)

Bacterium Splash Potion:
Throw the splash potion and the bacteria will infect the block it hits.

Isolation (Bricks by default):
Build a rectangle/square/circle/whatever horizontally on the ground and place bacteria in the middle! they won't eat below it so they won't grow out of the area you defined!

The world has been hit by a new and presently unknown infection which has wiped out most of the world's population. You are one of the few who have survived and now you must search this new wasteland in order to fight for your life against what is left of the indigenous population, now infected with the disease. Go solo or team up with friends and take on the world as you choose your path in this brutal and chilling landscape using whatever means you stumble upon to survive.

DiseaseCraft is a mod that adds 8 new diseases that alter the player's movement and everyday life. These can be achieved by simply hugging a rat, eating raw meat, or exploring long distances. Create/Trade medication, which can help you or harm you. Try to survive and thrive as disease and plague sneak towards you at every corner!

This mod tries to guilt players about the helpless creatures that they’ve killed by leaving a solemn reminder floating around their heads. These reminders may eventually fade away over time… or they may stay forever. Spooky.
