Arkham Horror LCG: Edge of the Earth (Investigator Expansion)

From Fantasy Flight Games:

In the far, uncharted reaches of Antarctica, unspeakable horrors dwell on the edge of shadows. They lurk, wait, and watch, and with them comes a secret so ancient and profound that it threatens to tear apart our very understanding of the planet we call home- if it doesn't tear apart reality itself first. Thus, our intrepid investigators must delve into the mysteries of the great southern ice sheets and, hopefully, uncover the truth before it is too late. 

In the Edge of the Earth Investigator Expansion, you'll find a treasure trove of player cards the likes of which you've never seen in Arkham history. With five investigators and around 250 cards to expand your deckbuilding options, you won't want to miss this opportunity to strengthen your player card content like never before.

This in not a standalone game, Arkham Horror: The Card Game core set is required to play!
