From their announcement:
The Vortex: Core Rulebook contains rules for building Combatants, over 270 Abilities, Liabilities, Weapon Features and Flaws, dozens of pre-constructed Combatants, an amazing array of Scenarios, and a complete easy-to-play Campaign System that allows your miniatures to gain experience and grow as characters. Vortex is also perfectly suitable for single games and tournament events.
Set within the Infinite Continua, Vortex is what you make it. Players are free to write any sort of back-story for their Combatants and Companies. You can play with historical accuracy or pure flights of fancy. You can create your own universes or play using existing literary or cinematic fare. The story of Vortex is every story.
The Vortex: Basic Battlefield Rules are available as a free download. This quick-start version of Vortex contains everything needed to play the basic game.
