The anatomy of a standard mk.1 Bean.
They are simple beans, with a basic understanding of the world around them. All they know, is that they are hurled into an arena filled with weapons and ammo...and other beans.

They don`t know where they came from, any history or culture. There are some hints dotted around the maps, but most beans aren`t long for the world and they generally dont pass on any newfound knowledge to their peers. also, they`re only capable of simple communication. Grunts, oofs and the often used Ouch. There`s only so much they can say to each other when theyre throwing lead at high speeds towards each other.
