Once upon a time… the world ended. No one knew where they came from or what they wanted, but they took everything. They called themselves the World Order Liberation Force or W.O.L.F. We fought back as best we could… The survivors now live in three hidden undergroundc ities, each run by a resistance leader, ex-cops colloquially known as “The Three Pigs.” Now we fight to survive… We fight for our happily ever after.
