This is my second apocalypse that I'm playing within the current install. The last one I failed because I accidentally cheated before medical was unlocked (litter box). I've done this before and am using the same print-out of the rules I had six years ago (environmentally friendly simming). There's not much else to say, so go ahead and start reading:
(1) The Whitehalls
(2) Gloria & Simon
(3) Melody & Natalia
(4) Melody & co.
(5) Judith and Siblings
(6) The End
