Cyber puns!

Well I started on Old World Blues, and it is rather silly!

The Courier gets teleported to a old scientific research base in the middle of what's known as "the big empty", and the place is run by 5 brain in floating robot bodies with 3 monitors for faces. Upon arrival the courier's heart, spine, and brain are roved, the last one disappearing some how. Now the courier has to help the 5 brains in order to recover their own and take down the evil 6th brain.

Turns out the place is actually called Big MT, but the first ones who escaped read MT not as "mountain" but phonetically as em-tee, hence "big empty". A Piers Anthony level pun. The brains have very weird personalities, one can't talk, one always shouts, one is filled with cold war paranoia, one is an incompetent robotics expert, and one has a fetish for organic movement.
