This expansion for Airborne in your Pocket allows you to combine 2 different games: AIYP and D-Day Dice. How does it work? Easy: when you play D-Day Dice and your unit enters the bunker, you must play a mini-game of Airborne in your Pocket to see what happens inside! Also includes cards that can be added to either game: AIYP: 43 dice-based cards, including a new set of events, new scenarios and many items and Special Ops D-Day Dice - 12 Airborne-themed awards, items and Specialists. Do you dare find out what is inside the bunker? —description from the publisher
