My Idea is this, you spend one day of the game in your home, doing everyday things like going to work, partying, whatever, then you hear a report on the news that there has been an outbreak, a zombie outbreak, everybody starts panicking and makes an attempt to evacuate the town, your first choice is whether or not to leave, and subsequently, who to go with, chances are most will choose to stay, slowly but surely attempting to zombie proof their house,the next few day you will see and hear nothing, simply going out and collecting supplies, occasionally encountering other survivors, then on the third day a car will drive through town and break down close to your house, if you choose to investigate, you will find an old man and a young sexy lady, already bringing ideas to the players head, and as the days pass you all head out and search for supplies together, until they come, hundreds of zombies moving through the town, if you're unlucky enough to be outside you will have to run and hide, resisting the temptation of shooting, thye do not leave though, and start swarming around a building down the street, hearing gunfire you see that there are people in that house, In the end the main idea is to get oput of the country (E:G Boats or planes) or to eliminate every zombie in the country (ooh big choice) and the main area of the game will be avoiding zombies, gathering supplies, and then hauling ass when the zombies find you, then subsequently finding another stronghold, and if they are manned, either killing all of the occupants or befriending them, your main problem will be friendly fire...(E:G being mistaken for the wlaking dead) and having to leave teammates behind when they get bitten or if you run out of resources. One possible scenario is a millitary base, fully manned and operational, but upon entering they demand that you give them all of your weapons to preserve order, infected get in and you are forced to start from scratch with no weapons or vehicles except what you can grab on your way out.
