Inside The Bunker - D-Day Says

Inside the Bunker simulates the bunker conquest of any D-Day Dice battle map using the inside locations of Paratroopers in your pocket. Or, if you prefer, it allows you to play a game of Paratroopers in your pocket as if it were the climax of a game of D-Day Dice. You will need components from both games in order to enjoy all of the content in this expansion (although it does contain components that can be added to both games independently).
