Aetherium: RezX Core Book is an expansion for Aetherium for 2 players and 60 minutes per game. It was designed by Brian Niro and Christopher Tavonatti and its main mechanics are Area Movement, Dice Rolling, and Area Majority / Influence.
The RezX live on the Aetherial frontiers, once the colonial research and development arm of the mighty RexCon. After RexCon was decimated in the First Great Trade War, RezX survived only through the quirky luck of position beyond the reach of nearly every other Aetherite. Now RezX sits on a precipice. With no more corporate tether, should RezX push further into the quantum noise or return to the Aetherial mainland and reclaim its once-proud position? 48-page full color rulebook includes the compelling history of the RezX faction, 3 new Operations, description and rules for all 13 programs in the faction, as well as all faction specific rules. —description from the publisher

The catalogue lists Aetherium: RezX Core Book as an expansion for Aetherium.
