It places players in the aftermath of a large scale zombie outbreak and tasks them with simply surviving. Scavenging takes a large role in the game as ammunition, guns, vehicles, and food are all scarce as would be expected. The player is left to decide how to progress in the game, be it to become a raider, to rescue other survivors, or to simply scavenge what you can find as a lone wolf. The story missions can be taken as often or as little as the player desires, similar to other open-world games.
