The following info is from facepunch as its hard to explain it all in my words
FIRST OF ALL — YOU WILL DIE
You’re trapped in a quarantined city with a million zombies. There is no escape. There is no cure. The end is coming, so get used to it.
Project Zomboid is about the choices you make, and how you choose to live your last days on Earth. As a hero who goes out in a moment of heroic self-sacrifice to save a defenseless family? Or a callous coward who saves his own skin and leaves his companions for dead?
It’s these choices, and the story you weave in your adventure. That is what Project Zomboid is all about. Not saving the world with some pie in the sky cure, or flying away in a helicopter where everything will probably be okay. This is the apocalypse.
MIND AND BODY
You can sustain injuries to any part of your body, from a broken leg to a concussion. These will need to be bandaged, set, cauterized or otherwise dealt with to keep you going. Illness and disease is also a real possibility, so better bury those corpses in the garden or set light to them before you catch something, because the hospital’s a long way away!
But it’s not just physical injuries that you can be inflicted with. The zombie apocalypse is hard to deal with, and it’s easy to sink into depression, or worse. You must try and keep your morales high, your stress down, and take some time for the little things to keep you and your companions sane. A hot shower, a cooked meal or a bit of music will go a long way.
If people are at the end of their rope, they may become withdrawn, fight, cry, or even stick a gun in their mouth and pull the trigger (which makes a lot of noise!). Paranoia can fool the senses and outright insanity isn’t easy to come back from. Cigarettes, alcohol and drugs can keep the darkness at bay, but rely on them too much and you may get addicted.
THE WORLD
As Project Zomboid develops, we will be adding new areas to the world, so that eventually you will have a huge city and surrounding suburbs and countryside to explore. Any building can be used as a safehouse, and any building can be looted for equipment to help you survive. You can hunt out weapons at the local gun shop, anti-biotics at the pharmacy, and food at the local market. But at a pinch raiding people’s fridges, sheds and medicine cabinets will keep you going.
THE STORY
Right now, the outside world knows nothing about the zombie threat. The government has quarantined the city, and cut off all communication with the outside world. The news is rife with speculation about the events that are occurring in the city borders. Soon they will know, and wish they didn’t. The quarantine can’t hold forever, and just outside the exclusion zone lies the still operational local power plant. Once that goes, batteries and canned food will be worth more than their weight in gold.
As you play Project Zomboid, the longer you survive, the game-world changes around you as the apocalypse develops. You can keep up on current events by turning on a radio, and those events will affect your situation as time progresses. You may even be able to influence them.
