From the publisher, Fantasy Flight Games:
The Masters of the Void are at war. Tearing through the fabric of the universe, they are summoning their minions and strongholds from across the planes to do battle and help them dominate the center of existence itself: the Vortex. For the one who controls the Vortex controls the universe.
In Maelstrom, you play a Master of the Void, fighting your opponents for control of the Vortex. Build your army of minions and strongholds, summon them to the battle, and unleash them against your opponents’ forces. The Expansion Pack gives you more minions and strongholds to control and help you gain control of the universe.
The Maelstrom Expansion Pack is designed to supplement and expand Maelstrom. The Maelstrom Expansion Pack contains 15 assorted flats containing 45 tiles not available in the Maelstrom set. Maelstrom is playable in 30-90 minutes.
