King of Tokyo: Halloween

King of Tokyo: Halloween is an expansion for King of Tokyo, themed around the holiday Halloween. It adds two new monsters and costume cards.

Description
King of Tokyo: Halloween adds costume cards, a new form of power card. As monsters dress up, they gain strong new powers but these cards can be stolen by another monster.

Halloween also adds two new monsters; Pumpkin Jack and Boogie Woogie. Evolution cards for these monsters are also included to be used with King of Tokyo: Power Up! . These monsters are a new species; Halloween.

The game also includes orange versions of the game dice. The original 2013 printing includes a promo card for King of New York, 55 Central Park West.

Variations
The first edition was released in 2013, for use with the first edition of King of Tokyo. This edition includes a promo card for King of New York, which had not been released at the time of printing. A variation on the first edition was released in 2014; while otherwise identical, this version does not include the promo card and the text on the back of the box is updated to reflect this.

The second edition was released in 2017. The contents are functionally identical to the 2014 printing, but have updated art.

Rules
Costume cards are shuffled and each player is given two at random; they choose one to start the game with, and all other costume cards are shuffled into the power card deck. When drawn, they can be purchased with energy as normal.

Costume cards are bought and kept permanently, similarly to keep cards. However, they count as a new type of card, separate to keep and discard cards. There is no limit to the number of costume cards one player can have. If a player rolls three or more claws, they can steal costume cards from monsters they damaged; to do this, they must pay the energy cost again. Multiple costume cards can be stolen at once, if the player has enough energy. The other effects of the attack are still carried out as usual.

Evolution cards are included to be used with King of Tokyo: Power Up. These feature gift evolutions, a new type of evolution card. When a player damages a monster, they can also use a gift evolution on them. This evolution stays in front of the damaged monster permanently. The owner is the monster listed on the card, and the card affects the player it is in front of.

Compatibility
The first edition of King of Tokyo: Halloween is intended for use with the first edition of King of Tokyo, and the second edition with the second edition. However, both versions of the expansion and the base game are similar enough that any permutation can be used. As King of Tokyo Dark is also similar to the base King of Tokyo, it can also be played with the expansion.

Evolution cards are included for use with King of Tokyo: Power Up!. As with the base game, the game and expansion are meant to match in version, but all versions are similar enough that a miss-match will not cause any game play issues. Both expansion can be used simultaneously, or the Halloween monsters can be used without the costume cards.

The promo card, 55 Central Park West, is for use with King of New York, and can not be used with King of Tokyo.
