its a free to play MMO (KIND OF) Everyone is in the same server, its an old school online game. You can play it via browser or it has a standalone client you can download. Also the game starts you out as level 1 and there are daily missions as well as looting. At first you are in one outpost as there are several scattered through the map. Each one has harder zombies but better loot in return. You scavenge around the map doing quests killing bosses and looting buildings/areas. The outposts serve as a safe house where you can Buy/sell/trade items/ammo/meds/all kinds of stuff. You can also pick a class when you make your character, you can be for example a Chef, cook, banker, teacher, each one has differnt traits and it tells you what they can do. So theres alot to the game, just dont judge a book by its cover. once you start playing it and get used to it, it gets real in depth. There are stat points and differnt items require differnt stats in order to use them. Also certain weapons are good for certain things so you have to pick and choose what your going to be.
