Nightmare Expansion Rules

Evolution Cards: The worst part of the Nightmare expansion? The zombies are...Evolving... After an event triggers an evolution card draw, a card or cards are drawn from this new deck.  These cards give benefits to zombie players. The event card drawn will indicate if these are drawn face up or face down and whether they persist in the absence of current player zombies or are discarded. Otherwise, apply them as indicated on the card at the time they are drawn.

Additional Event Cards: More things can happen...and in nightmarish fashion most of these are BAD events...prepare for your worst nightmare. Here we will have more general events, but also introduce cards that give players additional conditions to complete before being able to win the game, and card that trigger zombie player evolution. Some of these evolution cards are discarded if there are no zombie players, but some persist even if there are currently no zombie players, and take effect when there are. Each card will indicate whether it is persistent or not. Keep the event card(s) and evolution card(s) next to the player that drew them until they take effect. Otherwise, treat the new event cards the same way as original event cards.

Additional Blood Cards: More likelihood of infection? Extended infection countdown for a blood card already received?  Sounds fitting for a nightmare. A new type of blood card causes the player to take a new blood card upon reveal of the current card, extending the potential infection time.

New Cards: All new cards have a new card back. All recurring card types are marked by face design color or the biohazard icon for ease of removal from the basic game in case you want to play a more standard game. (For the faint-hearted.)

Player vs. Player Combat

Since killing zombies apparently wasn't enough, we introduce Player vs. Players combat. 

A human player can only engage another human player in combat under the following conditions:

• Both players must be on and stay on the same space. No "hit and runs."
• The event card(s) for all spaces have already been resolved.   
• The target has an unconfirmed status. (One or more unrevealed blood cards.) 
• Only one combat per target may be initiated per player each turn.

Combat follows the same order as player vs. zombie combat. First, players will have the option to shoot, then players will have the option to engage in melee combat. However, players are not zombies, so a bullet does not guarantee an instant kill, and the defending player can fire back at the same time.  Each player being shot at will draw a determination card. The targeted player draws first, then the aggressor if the defender has any bullets of their own and chooses to use them.  A draw of 8,9, or 10 will mean that the player dodges the bullet. Otherwise, the player dies.  If neither player has bullets, or no player is killed during the gunfire phase of combat, then melee combat can be joined.  The targeted player draws the first determination card(s) in melee combat. All players must choose any weapons they wish to use before determination cards are drawn for melee combat. 3 or more players must engage in melee combat to kill a player without a weapon, and all three must win over the defending player or he will survive. High draw wins the melee combat in normal fashion. If the defending player has and uses a weapon in melee combat, and defeats the aggressor(s), then the defeated aggressor(s) are killed.

If the targeted player dies they become a zombie on the same space they died on. If any aggressor of the combat dies, they become a zombie 11 spaces behind the current space (Not a typo, that is 1 more than the normal maximum movement) and take their zombie turn as normal.
