Exodus: Edge of Extinction is the first expansion of Exodus: Proxima Centauri (revised edition). The original Exodus: Proxima Centauri was a distinguishable entry among other 4X games of the new wave, leaving its unique mark on the gaming world. With a game play focused on high-octane conflict fueled by raging war and cutthroat politics, it also introduced players to a rich science fiction setting, with its own back story and its own secrets. Exodus: Edge of Extinction expands both the gaming and the narrative aspect of Exodus: Proxima Centauri into an even more epic space strategy empire building game. Exodus: Edge of Extinction represents the next chapter of an immersive story in which the remnants of humanity go to war against each other over a system they believe to be Proxima Centauri. Each player leads one of six unique factions with their own histories, strengths, unique special abilities and a set of new, exclusive technologies. Exodus: Edge of Extinction also brings larger fleets, custom action cards and completely new mechanisms like the Combat Cards, adding a whole new layer to the spectrum of strategies already available in the base game.
