4. DayZ

Are you ready for a zombie mmo?

DayZ is one of the first MMO style zombie games on the market. It is still in Early Access on Steam though so if you want to support it, head over there and sign up.

The zombie apocalypse has struck and you are one of the few survivors. You can choose to team up with other players or simply fly solo in order to survive. Weapons can be found or crafted, and later customized with unique mods that fit you the best.

The reason this game is so addicting is because of the online multiplayer nature of the game. You don’t know if you’re going to get killed by a zombie or your next door neighbor.
