KeyForge Adventures (sometimes stylized as Keyforge: Adventure) are a co-operative method of playing KeyForge, initially announced by Fantasy Flight Games on March 11, 2021:
Fantasy Flight Games is proud to announce that cooperative play is coming to KeyForge in two free-to-play adventures that expand upon the themes and mechanics found in Dark Tidings.
Both of these new adventures, Rise of the Keyraken and Abyssal Conspiracy, replace the opponent with an automated deck that each player must draw from when their opponent would normally take a turn. The cards in this deck contain actions that are performed against the players, creatures for the players to fight, and artifacts that the players must avoid or overcome. In this way, any KeyForge deck can be used when playing against either adventure. However, because each adventure has a unique victory (and loss) condition, players may find the decks that are most effective at winning in this new game mode are not the same as the ones that are that effective in standard KeyForge play.

After defeating the Keyraken, the Archons find that the danger has not yet abated, for their ship is crippled by a mysterious saboteur who escapes before justice can be served! In the second adventure, you must navigate a grid of nine locations as you descend into the ocean’s depths to uncover the conspiracy and find the tool you will need to put an end to its villainy. Exploring the ocean’s depths is a dangerous and uncertain undertaking, and whatever force is attempting to foil the Archons is not waiting around to be stopped.
