Overview
Welcome to Brainium, im sure you can guess what this mod aims to achieve so let me get to the details.
Brainium is an infection mod where these strange little brains will randomely appear around your world with the sole purpose of finding a suitable host. Its up to you to prevent this from happenening because when they find a host, a chain of events follows leading to mass infection spreading across your world.
Luckily at every stage there is always hope to stop the Brains, however should they reach the final stage your situation becomes much more... difficult.
Features
- World Infection (block corruption)
- Reversible Infection (block corruption reversal)
-Weapons and armor
-Mobs with unique AI for hive-like behavior
Mod Contents

These small creatures spawn randomely at night and seek out a host. They will pull in mobs into a ring where they will slowly drain the mobs to allow itself to grow.
Brain Master:
A well fed Brainium turns into this brain master, it fires lasers, destroys blocks, shoots fireballs, and more to protect the brain infection from being stopped.
Infection
Brainiums:
The Brain infection will slowly spread once a brainium can become a brain master and begin the infection. The only way to stop and reverse it is to destroy the brain master, the infection will automatically reverse itself afterwards returning your world mostly as it was.
Final Stage:
If the infection spreads for long enough it the brain master will center itself in the infected landscape and begin extracting iron from your world to reach its final form and almost guarantee the brainium infections protection.
Corruption Walker:
A new set of armor added to help fight against the brainiums. The primary feature is its defence mechanism. Upon being damaged flying crystal shards will appear to then home in on your attacker and deal damage.
Field Generator:
A new weapon where the player can pickup entities and throw them around. Similar to a gravity gun in gmod, and particularly useful is stopping mobs from trying to rush you.
End/Plans
Currently I am planning to complete the player infection feature allowing players to be automatically controlled to move. Most importantly after finishing the brain hive mind behavior fully I plan to add actual infected mob models for many vanilla mobs to bring the mod to life a bit more. Id like to keep the mod small as it was primarily a project I wanted to do for fun and I do have some more mod ideas in mind too.
If you have any suggestions or ideas feel free to leave a comment on the mod page or join the discord if you would like to chat about the mod.
