Get both base games, and a killer mini expansion for each!

What happens when both slashers stalk the same deck? This crossover booster lets each killer invade the other's game.
 
Drop the Psycho Killer — plus a new set of Cleavers, Machetes and Axes — into your Killer Queen base game. Use the weapons as a simple reskin, or shuffle them in as a mini-expansion: play as normal until someone draws the Psycho Killer, then everyone dumps their PK weapons straight into their Injury Pile.
 
Unleash the Killer Queen on your Psycho Killer base game, with five new weapons and all three Killer Queen cards re-cut for the PK format — Sudden Death, Terror Rising and Final Cut, each with a deadly new trigger.
 
Requires the Killer Queen and/or Psycho Killer base game to play.
