The dead keep on giving with developer Hammerpoint Interactive announcing that their zombie themed survival MMO The War Z will be opening alpha access to those who have yet to taste the wind of Colorado.

For players who purchased the base pre-order of the game, access to the alpha will be available starting tomorrow, with guest passes also being available for use. For those wondering how to celebrate Halloween in The War Z, Hammerpoint has announced new content that will be available tomorrow, including new zombies and more of the map opening up.

With a current player base of more than 200,000 gamers, the time is now for remaining survivors that have yet to get their first taste of The War Z. The game is available for unrestricted access on October 31, 2012 and, to celebrate, developer Hammerpoint Interactive is introducing brand new content that will feature the following:

New Characters – new playable characters

New Zombies – new zombie models

New Playable Area – entirely new section of game world opened up, including new large cities – effectively doubling the current map size

Special Themed Items – players will have access to special, Halloween-themed items in the game marketplace

Adventurers of the zombie apocalypse will also be glad to know that starting tomorrow, the NDA that has been blanketed over testers will be lifted, meaning anyone can stream content and talk freely about the product without worry.

The War Z is currently in alpha development, with no release date announced yet.
