Elder Sign: Gates to Arkham Expansion

Four new Ancient Ones threaten humanity and eight new investigators join the quest for elder signs. Investigators can also now acquire skills that give them lasting advantages. Memberships in either the brutal Sheldon Gang or the mysterious Silver Twilight Lodge help investigators complete tasks and grant them added rewards. It will take all the skills, resources, strength, and sanity you can muster to prevent the Ancient Ones from awakening – and to stay alive in the rough streets of Arkham.

This is just an Expansion! You need the core game "Elder Sign" to play with it.
