For The Greater Good is the third Mythos Pack in The Circle Undone cycle for Arkham Horror: The Card Game.

Following the events of The Wages of Sin, you are disturbed to learn that there have been even more strange sightings in Arkham and worse, several more people have disappeared. You need help. Your relationship with the Order of the Silver Twilight cannot continue to balance on the edge of a knife. You must decide whether you will place your trust in them or count them among your enemies, and this decision will shape your adventure moving forward, determining your ties to the Lodge and which areas of the manor you will have access to.

At first glance, several of the player cards featured in For the Greater Good may look  familiar. In The Secret Name, the Arkham Horror LCG broke the boundary between player factions by introducing player cards like that belonged to multiple classes. Now, as your investigators continue to gain experience from their research into Arkham’s secret history, you will have the chance to upgrade these cards into more powerful versions that fit into classic, single-class categories. Each version of these upgraded cards feature distinct art pieces and abilities that play into the core focuses of their classes, growing with your investigators as their search for answers continue.

This is not a standalone product. A copy of the Arkham Horror: The Card Game Core Set and The Circle Undone deluxe expansion are required to play.
