Modules
Plethora comes with several other modules which allow interacting with the world
The neural interface
The neural interface can be put in your armour slot and interacted with like a computer. Modules and other peripherals mounted on it get full access to the player.
Laser
You can fire lasers
Controlling mobs
You can attach the neural interface to mobs too: and control their movement.
One simple request
Squid with frickin' laser beams attached to their heads!
