Zpoc is a single-player sim game of moral exploration in an apocalyptic survival situation. You are not just one person trying to make it in the end times, but you lead a colony of people to either flourish or perish.
How will you survive? Zpoc includes the classic survival objectives such as building a shelter, finding food sources, gathering resources, and fending off enemies. But this is all just a base for the bigger question -- how far will you go to survive?
If you have barely enough food for the members of your colony and a random solo survivor asks to join, do you recruit them and figure it out, or do you turn them away to what will almost certainly be their doom?
Do you reward your dog’s loyalty by protecting it from zombies, or do you sacrifice it to a zombie horde in order to distract them, perhaps giving your people a few extra seconds to escape?
A member of your colony drinks too much, eats too much and doesn’t work as hard as the others. You could confine them, but then they’re using up resources and contributing nothing. You could invoke corporeal punishment - but are you leading that kind of society? You could send them away, but exile is almost certain death when just outside your barriers an unsleeping horde of the undead waits to devour anything living.
Every choice you make, every colonist your recruit, your relationships with other groups of survivors, and even the way you build your base will determine who leaves, who joins, who lives, and who dies. The culture you create affects all of its members, and each of the members in turn affects that culture. Each person you see in the game has thoughts, emotions, skills, and desires, and every action the colony takes will shape those feelings - and ultimately your society as a whole.
All of your units will have personal relationships with each other as well as with rogue units and members of other colonies. While good relationships will lead to enhanced teamwork and mood boosts, bad relationships can lead to name-calling, fighting, and even murder. These unscripted rivalries and friendships are the core of Zpoc’s emergent storytelling, and will give it infinite replay value. The best of friends may be torn apart (literally or figuratively) in a zombie hoard, but the worst of enemies may learn to respect each other if they have each others’ backs on the battlefield.
It’s up to you to determine right from wrong, but watch out for those who might disagree.
