Rules Update 11:00 AM EST September 15

Rule clarification: #Weapon rule may only be used on one zombie at a time. #Weapon tweets with more than one zombie included in the tweet are invalid and wasted.

New rules:


Each zombie may earn one additional #zapbite between now and the end of the game.  Refer to last night’s rule release for #zapbite mechanics.  A #zapbite is permanent and a zapbitten zombie is not vulnerable to an #antidote.


A HUMAN can earn one vial of #antidote for the remainder of the game by posting a substantive video of at least one minute (language for “substantive” blog posts below applies to videos as well). An #antidote my only be used on one active zombie, and turns that zombie back to human for the remainder of the game — essentially making that zombie a superhuman who has no more vulnerability to #bites (of any kind). An antidote will not work on a zombie who was turned with a #zapbite. Using an #antidote makes a human vulnerable for a full five minutes and cannot be used in combination with #picsafe. It cannot be used from within a #safezone. Tweet must include #TvsZ, #antidote, a link to the video (which must be publicly hosted somewhere where everyone can see it), and the name of only one zombie. Each specific human may only use #antidote once from now until the end of the game (essentially works like #zapbite).


A ZOMBIE may earn five minutes of unlimited biting by posting a substantive video of at least one minute (language for “substantive” blog posts below applies to videos as well). During that time, the zombie may #bite as many humans as he/she wishes, but may only #bite each human once. #Weapons will not work on a zombie who is rampaging. During a #rampage a zombie can still use #zapbite. Because a zombie may continue to use #rampage throughout the game, each video must be a substantive and creative addition to the game — not just a continuation of the previous #rampage videos. Tweet must include #TvsZ, #rampage, and a link to the video (which must be publicly hosted somewhere where everyone can see it).

Rules Update 11:00PM September 14

Sorry for the late release tonight everyone! We have a few tweaks and some brand new rules we think you’ll like!

First, we’re giving all humans the technology to make their #safezones impenetrable for the full hour they are active.  What this means for zombies is that the #overrun game action is dead.

And now for the new rules:


A ZOMBIE may earn a #zapbite by composing a substantive blog post that includes a picture or video (see language defining “substantive” below). A #zapbite is an indefensible bite. When used against a vulnerable human, that player immediately becomes a zombie — no #dodge or #swipe may save him/her. A #zapbite may not be used against a human in a safezone, and if it used against a human who is not vulnerable, it is wasted. A zombie may only earn one #zapbite between this rule release and the next rule release (at 10am EST Sunday morning). A #zapbite tweet must include the #TvsZ hashtag, a link to the blog post, #zapbite, and the @name of the targeted human.


HUMANS can take a picture of a weapon (be creative — hit the zombie with a book, stab the zombie with an icicle, drown the zombie in a cup of coffee), attach the photo to a tweet and stun the zombie with the #weapon. The picture must be taken with your own camera, not something swiped off the internet, and it should be taken specifically for the game. Your text should include a creative way of using some random item as a weapon. A #weapon will prevent a zombie from biting anyone for 30 minutes. Tweet should include the #TvsZ hashtag, the @name of the targeted zombie, the picture, and the action tag #weapon. A HUMAN may use a #weapon every 30 minutes (similar to a zombie’s usage of #bite). #Weapons may be used from within or outside of a #safezone.

Rule clarification: #Weapon rule may only be used on one zombie at a time. #Weapon tweets with more than one zombie included in the tweet are invalid and wasted.


Definition of “substantive”

For the remainder of the game a blog post may only be counted as “substantive” if it is of substantial length (we are refusing to define this to keep anyone from bean-counting) that also does at least one of the following things: advances the narrative of the game, reflects on the actions of the game so far, reflects on the lessons learned during the game (digital, communal, or otherwise), OR collects and reflects on some of the player’s favorite moments of the game (with links, embedded tweets, etc.). Remember the spirit of the game here:  a substantive blog post earns us something in the game; we should have to work for it. Additionally, blog posts can be playful, but should do so without being offensive or aggressive.

Rule disputes

In order to highlight the communal nature of the game, any player with a dispute about a particular rule should open up a thread on the G+ Twitter vs. Zombies Community asking for a group ruling. He/she should then post to Twitter with a brief description of the dispute and a link to the dispute post (which can be isolated by clicking on the timestamp of the post and copy/pasting that URL in a tweet). All members of the game are permitted to weigh in on this by replying to the G+ post, and because this action happens outside of Twitter, humans and zombies can thresh it out together. Game admins will issue a ruling on the matter ONLY if, after 10 minutes, players cannot come to a consensus. In the spirit of the game, clearly tweeting a link to a dispute post will not make a human vulnerable to being bitten.

Rules Update 10:00 AM EST September 14


A HUMAN player can create 1 hour of protection by writing a substantive narrative blog post that includes at least one visual element (picture or video) about the game and tweeting a link to it. The HUMAN player can pull other HUMAN players into the #safezone by including their names in the original #safezone tweet. The #safezone action tweet must include: #safezone, #TvsZ, a link to the blogpost, and the names of the human players included in the #safezone. Once in the #safezone, those HUMANS can tweet with immunity for exactly one hour. If a #safezone is #overrun, all humans in the #safezone are vulnerable to attack, whether they have tweeted or not in the last five minutes.


A ZOMBIE player can #overrun a human safezone by publishing a blog post that substantively responds to a particular human #safezone blog post and that includes at least one visual element (picture or video) . Once an #overrun action tag is used, all humans inside that #safezone are vulnerable to being bitten by any zombie whether they have tweeted in the last five minutes or not. The #overrun tweet must include #overrun, the link to the blog post, and the link to the blog post that was acting as a #safezone, along with narrative content. An #overrun tag does not serve as a #bite.


A ZOMBIE can #purgebite a human player, whether active or not, if that player has not tweeted 10 times in the first 24 hours of the game. ZOMBIE players must verify for themselves that the HUMAN they are targeting has tweeted less than ten times since the beginning of the game and then can attack with an action tweet including #TvsZ, their Twitter handle, and the action tag #purgebite.  If the target does not defend him/herself or is not defended in the following five minutes, the zombie may change the human’s status in the game scoreboard to zombie.

Rules Update 10:00 PM EST September 13


A HUMAN player who wants to comment in the game without risking infection needs to attach an original photo to the tweet along with #picsafe and #TvsZ. The photo should add to the narrative of the game. If your tweet has a photo attached and the #picsafe, #TvsZ hashtags, zombies may not bite you for that tweet. Other tweets will still leave you vulnerable. Humans may not post consecutive #picsafe tweets. You may recharge your ability to use a #picsafe tweet by making a regular tweet.


A ZOMBIE player may earn an  #extrabite by composing a tweet with an original, relevant photo OR short video (for example, Vine) that adds to the narrative of the game. The tweet should include #TvsZ, #extrabite, text about the significance of the photo, and the @name of the victim.  A zombie may only use one #extrabite per thirty minutes.
