In the game, the player has to collect supplies in forests, mines and different special locations to build houses and make weapons/tools. At the same time, players need to satisfy their hunger and thirst. Sometimes there will even be body cleanliness, internal urgency and coldness appear. Players can fight with zombies or hostile survivors and attack hostile players' bases to get different rewards. Players can also raise puppies as their companions, protect themselves and go to inaccessible places.

The game is set in 2027, when a flu outbreak occurs. The pandemic wiped out most of the world's population and turned them into zombies. Although the player has antibodies to the virus, he needs to beware of the zombies and other hostile survivors who can still do harm.
