[Mojo]

DLC is coming out which allows playing after the main quest. No idea how they'll work it into the story, probably some cop out where you wake up on a hospital bed recovering from radiation sickness or something.

Spoilers:

That would be pure magic, as you turn into a puddle of goo when you turn on the machine in the end... As seen in one of the clips in the ending, where Lyons is watching you through the glass...
