For those players who were eager enough to pre-order the Pioneer and Legend pack for the upcoming zombie survival MMOFPS, The War Z, will be glad to know alpha access has opened up today.

Currently the alpha is limited to 30% of the initial map, Colorado, with more to open up as testing moves forward. This version will also feature a slightly higher spawn rate for weaponry and attachments, plus the usual array of bugs in such testing conditions.

The War Z is an online, multiplayer, survival-simulation game set in an open world infested with zombies. Players are thrust into this post-apocalyptic world five-years after a viral outbreak that ravaged the human population and left, in its wake, a nightmare of epic proportion. Hordes of undead zombies roam the cities, and the few remaining human beings have devolved into a lawless, nomadic society where the sole objective is to survive at any cost.

Players must use skill and cunning in order to acquire food, weapons and other supplies necessary for survival. While navigating the vast landscape, they will discover cities teeming with the undead as well as other players that may or may not be friendly.

Players participating in the alpha test are also reminded that an NDA is in effect until November. Director Sergery has released a guide on what to expect in this alpha test, which you can read over here.
