As empires expand into space, they encounter mysterious alien artifacts and races uplifted to sentience eons ago. Meanwhile, Imperium factions provoke other worlds to ally and rebel as the galaxy drifts towards war. Can you build the most prosperous space empire in these challenging times? Expansion and Brinkmanship bundles 3 previously published expansions (The Gathering Storm, Rebel vs. Imperium, and The Brink of War) into a single product, now compatible with 2nd Edition Race for the Galaxy.
