<P> While the game includes wildlife that can be hunted for food or will hunt the player, the main hazard are zombies, which are affected by the game's day / night cycle - during the day they are relatively slow - moving and easy targets that can only detect the player at relatively close ranges, but at night they become feral, which makes them move much faster and thus greatly increases their threat . As the in - game days progress, tougher and more aggressive variants begin to appear . Stealth and distraction can be used to avoid unnecessary conflict, while carrying foods that have a smell (such as raw meat) will attract zombies . They are also drawn to areas of human (i.e. player) activity, and will relentlessly attack anything that impedes their movement until they are killed or the obstacle is destroyed - this includes player fortifications . Should they detect the player, zombies will apply the same single - minded pursuit until the player is either dead, or leaves the immediate area . </P> <P> The game's title is a reference to an important event that occurs every seventh day of in - game time, whereby hordes of zombies attack the player's current location en masse - unless sufficient preparation has been made and defences constructed, the player will quickly be overwhelmed . </P> <P> Multiplayer is available through player - hosted servers and enables multiple players to interact and communicate with each other on a single world . Interactions can be cooperative or hostile depending on the used server options . Players can run their own servers or use a hosting provider . Single player worlds have local area network support, allowing players to join worlds on locally interconnected computers without a server setup . Players are also able to provide Wide Area Network support via single player worlds . 7 Days to Die servers can run on both consoles, Windows and Linux . There are two supported game modes for multiplayer: Survival (both randomly generated and standard) and Creative . </P> <P> The Windows alpha version of the game was released on August 16, 2013, for people who pre-ordered the game on either Kickstarter or PayPal . As of August 11, 2013, development of the game is ongoing with a Kickstarter campaign ending on August 15 . The estimated release date was May 2014 for Microsoft Windows; Macintosh and Linux versions were planned for later in the year . </P>
