About Ace of Spades: Call of the Zombie, from BoardGameGeek:
Legend says that Jack would go into the saloon every night in search of a little entertainment and something to wet his whistle. One day, he walked in on his old friend who owned the saloon in the process of watering down the whisky. This betrayal was so unforgivable that Jack killed the man on the spot, drowning him in a filthy watering hole.
But his rage was not quenched, and he vowed to master dark magic so he could bring the bartender back to life and kill him anew every night until his thirst for vengeance was satisfied. He has been at it for 723 nights, and he ain't gotten tired of it yet. The moral of the story: never water down the customer's whisky! Anyway, his wicked powers have led to his being proclaimed the Hellbilly Zombie Master, with his very own army of zombies ready to do his bidding. You are the only one who can put him and his putrefied horde of living dead in the grave.
The first expansion for Ace of Spades includes 15 new zombie enemy cards with 4 versions of the Hellbilly zombie master. In this expansion, the Enemies work slightly differently from how they do in the base game. When play them, cards in your Hand combinations will be "captured". This means that 1 (or 2) of the cards that damaged the Enemy will be linked to that particular guy and can never be used again. Enemies are zombies, so they never die. If you survive long enough, you will face a horde of undead.
