Exodus: General is an expansion which requires the base game Exodus: Proxima Centauri. The main component of the Generals expansion is the pack of 14 unique Ability cards, which add a special, once-per-game, special ability to each faction, adding an unknown factor to the game. These abilities are designed to influence the normal course of the game while still preserving the balance. The extra Centaurian Resistance cards are also part of the Generals expansion and they should be used together with the base game resistance cards. They provide more challenging Centaurian opponents and offer more important rewards.
