Rio Grande Games has announced the next expansion for the original deck building game, Dominion, will be released this October, Dominion: Hinterlands. The description from Rio Grande is humorous and provides almost no information about the expansion at all. What we do know is that the new expansion will add 26 new Kingdom cards to Dominion, including 20 Actions, 3 Treasures, 3 Victory cards, and 3 Reactions. The central theme is cards that do something immediately when you buy them or gain them.
