The new expansion pack adds two new factions to the game, The Moles and The Crows. The Moles are an ancient kingdom that has ascended to the surface with large amounts of Warriors to put on the map. Conversely, The Crows are espionage masters that score points with hand manipulation tactics. It also adds two new maps, the Mountain Pass and the Lakeside, along with specific rules for each map.

This expansion, in conjunction with the base game, supports two to six players, ages 14 and up, and plays in 90 to 120 minutes.

Leder Games also announced Fort and previewed it for ICv2 (see "Build the Coolest 'Fort' On The Block").
