Vortium is a collectible card game in an alien science fiction Universe. You are one of the Eternal, immortal and powerful beings that influence entire civilizations, and use them in their struggle with other Eternal to decide the fate of the Universe. You will open vortex in space, and through them you'll bring beings, devices, relics, ships, or use the energy to play actions, changing the course of the battle. Choose your allies between Shyr (reptilian fighters), Atlantis (aquatic humanoids), Meraq (gray geneticists), Al-Tuban (draconian conquerors), Tzabekh (humanoids) or the mysterious Nishtya.
You build two decks from your collection of cards: One of 50 cards, containing beings, devices, relics, ships, and actions from different civilizations, and another with 15 nexus cards, which you will use to open and enlarge vortex to different civilizations that will allow you to play the other cards.
Summon from their homeworlds different beings, enhance them with devices, or have them to pilot spaceships. Use relics from the Eternal to change the battlefield. You can attack your opponent's vortex with your beings and ships, trying to close them. Shut down all your opponent's vortex and you'll win the game!
