About these games

Sins of a Solar Empire: Rebellion

Sins of a Solar Empire: Rebellion is a stand-alone expansion in which you command a space-faring empire, blending the depth of the 4X genre with real-time strategy. The war has split the sides into loyalists and rebels within the Trader Emergency Coalition, the Advent Unity and the Vasari Empire, and playing as either unlocks new technologies, ships and play styles for each race. Titan-class warships and new capital ships with upgraded abilities join the fleets alongside nimble corvettes built to harass the enemy. The game also brings updated graphics, particle effects and lighting.

Sins of a Solar Empire: Trinity

Sins of a Solar Empire: Trinity casts you as the leader of a civilization caught in a galactic war, where the survival of your entire species depends on your decisions. The game merges the empire management and exploration of the 4X genre with the fast tactical pace of real-time strategy, and you switch between the roles of emperor and fleet commander with the game’s strategic zoom. Diplomacy, alliances, trade and hiring pirates, who grow stronger over time and can turn against you, help shape rivalries, while starbases and minefields protect your worlds.

Star Ruler

Star Ruler is a strategy game in which you command a vast interstellar empire and protect your species from total extinction. The galaxy is procedurally generated and three-dimensional, and you can optionally flatten it. Combat is intricate, and anything from individual ship components to the stars themselves can become a target. Besides researching weapons, engines and shields, you can negotiate with other empires, create and destroy worlds, and play against up to ten opponents online or over LAN.

Dawn of Andromeda

Dawn of Andromeda is a pausable, real-time 4X space strategy game. Players build their own empire, colonize new planets, interact with other factions and characters, research technologies and assemble fleets. The galaxy is filled with diverse factions, outlaws, merchants, pirate clans and mercenaries, as well as anomalies, black holes, ancient artefacts and ruins. Governors of colonies and council members can be appointed and levelled up, which reduces the need for detailed micromanagement.

Distant Worlds: Universe

Distant Worlds: Universe is a vast 4X space strategy game played in real time and pausable at any moment, offering turn-based depth with simple, easy controls. Its living galaxies hold other empires, independent alien colonies, traders, pirates and space monsters, and you can explore star systems, asteroid fields, supernovae, galactic storms and black holes. You can play through a storyline, with victory conditions, or in an open-ended sandbox, either as a standard empire or as a pirate faction. Universe is a collector’s edition bundling all previous releases, a new storyline and expanded modding support.

Star Trek: Infinite

Star Trek: Infinite is a grand strategy game in which you lead one of four major factions: the United Federation of Planets, Klingon Empire, Romulan Star Empire, or Cardassian Union. As the leader, you make the key decisions for your faction, and your choices determine how well you reach your goals. Diplomacy, espionage, warfare, or a combination of these can all lead to victory. Characters such as Picard, Janeway, Sisko, Data, Gowron, Makbar, or Garak can be recruited, and the game is built on core systems from Stellaris.
