No matter what happens to your pack, the game continues:
Survive Alone
Calamity has befallen you. You're once again a lone wolf who must survive against the odds. You probably want to find a new mate from the dispersal and pack wolves here or on another map...but you can remain solo for as long as you like.
If your wolf is female and already pregnant, you'll need to survive on behalf of that litter of pups. You may want to find a new mate to help raise them.
As a lone wolf, you can try to avoid hostile packs by wandering within the border zones, but you may want to claim a few territory hexes for some security.
Survive With Mate
If all your pups and packmates are gone, leaving only you and your mate, then maintain your territory, keep hunting together, and look forward to next year's pups.
Survive With Family
If all of your pups of the year die, life still goes on with your older offspring. Without a mate, you won’t have a litter of pups this year. Try again next year!
