Bulwark: Traitor's Crossing

From publisher description: Heroic Co-operative Deck-Building! What better location to defend than a muddy mess of a riverbank near a strategically-important bridge? After all, without the inconvenience of stout walls, gates and so forth, you can see all of the enemy arrows on their way to you. Unless, for some reason, you think that might be a bad thing... More Options Traitor's Crossing is a location with plenty of defender cards, meaning you can build a successful deck with relatively few hero cards.
