Enter the Lab of Evil with Kinfire Delve Callous' Lab!

You are Seekers, sent to confront the malevolent creature known as Callous. In Kinfire Delve: Callous' Lab, a tactical and cooperative card game, you will fight your way through the Well deck filled with challenges to reach Callous, the Master of the Well, and face him in an epic final battle.
Ready for unpredictable dangers and a constant struggle, your survival depends on teamwork. All players share a single health pool—if it reaches zero, you are all defeated!
You can only play skill cards from your hand if they match the color of the challenge card. If you fail to defeat a challenge immediately, you can add some progress, but beware of the penalties! Provide help to other Seekers by playing cards as boosts, even when it's not your turn. But be cautious—running out of cards will earn you negative "Exhaustion cards."
The player cards from this game can be used as alternate character skins in the Kinfire Chronicles Night's Fall board game!

How deep will you delve into the abyss to banish the evil spirit?

The game is designed for 1-2 players, but it can easily be expanded to 4 players by adding decks from other Kinfire Delve sets.
