House of Tenefyr is a dungeon-delving, fully cooperative deck-building game where you must outfit yourself with gear, head into the dark tunnels, and work together to slay monsters and defeat the boss at the end (hopefully, anyway). The Second Curse is a new expansion that fully doubles the options available to you when making your deck and setting up the dungeon. A new reprint of the game as well as the new expansion are up on Kickstarter now.
From the campaign:
Heroes of Tenefyr is a fully cooperative deck-building game for 1-4 players with push your luck elements. It's very easy to teach in less than 5 minutes, but winning can be quite a challenge.
Heroes of Tenefyr: The Second Curse is an expansion with new heroes, new bosses, new enemies and rewards. Adding the expansion doubles the amount of content and variety.
The campaign's more than 3x funded with 13 days left to go.
