On the Underground: Obstruction Promo

A new promo for both On The Underground games.

Setup: Before setting up the game, randomly draw three destination cards and place an obstruction tile in each of the stations they show. Shuffle those cards back into the deck.

Gameplay: A player must pay 2 branch tiles to connect a line to a station with an obstruction tile. That player then scores three points and removes the obstruction tile from the game.
