Hot on the heels of the new base game comes Clank! Adventuring Party: Master Thief Edition. As ever, the popular Adventuring Party expansion offers unique characters playable in both Clank! and Clank! Catacombs -- plus, it expands both games for up to 6 players.

Those unique characters (and their different starting decks) are getting tweaked for better game balance.
