This is intended to be a spin-off of the living vehicles that have appeared in the Insane CafĂ roleplays.
I'm not sure of the plot yet.
However, I do have a twist. The vehicles are "living" but they have Human riders (much like horses). The vehicles have full control over their bodies and electronic equipment. However, they cannot reload, refuel or repair themselves as they no limbs.
I had planned that one player plays the rider, the other plays the vehicle.
I'm open to ideas.
