RBI

I have personally decided that RBI stands for Really Bad Infection, but whatever, let's move on. You catch RBI by letting zombies hit you, please note it is completely random. It takes half a heart every 2 seconds (i think i will check it again as soon as i can). RBI can be cured by using an RBI cure Syringe.

A Whole List of Names we came up with:
