Galactic Civilizations III: Retribution Expansion (AppID: 976210)

What started as a crusade has become a war of retribution.

Across the galaxy, ancient alien artifacts are being discovered, giving civilizations powerful new capabilities. Meanwhile, as civilizations try to carefully balance building an economy, funding an ever growing war machine, and engaging in diplomacy, the humans of Sol III have invented a game-changing new technology - Hypergates - which, when connected, allow for rapid transit across the galaxy.

With two new major civilizations and the concluding campaign to the Galactic Civilizations III backstory that serves this massive space 4X sandbox game, Retribution asks the question: How will you rule your galaxy?

Features

• Artifacts - Powerful items buried on planets across the galaxy will give your civilization instant-access to new abilities.
  
• Hypergates - Construct powerful gateways that, when linked, allow your fleets to travel even faster across hyperspace.
  
• New Major Civilizations - The Drath and the Korath are back! The manipulative Drath pull the strings across the galaxy while the Korath rely on extermination. Each has its own set of special abilities, bonuses, and ship parts.
