The Data Core Expansion Pack includes 8 new Alien Tech cards to be used with the Alien Frontiers base game.

Included in Alien Frontiers Edition X but also made available as a stand alone expansion.

The expansion comes with a rules card and eight new alien technologies cards, two copies of four unique alien technologies. When playing with just the base game the rules recommend mixing only one copy of each alien technology into the alien technology deck. When playing with an alien technology deck larger than that included with the base game, whether from expansions or promos, then the rules recommend including both copies of each of the four alien technology cards.
