Our take on Infinite Space III: Sea of Stars

The description presents a galaxy-spanning adventure, but each run is framed as short enough for one sitting. Its replay value comes from randomly generated worlds and changing encounters rather than one fixed sequence.

What is Infinite Space III: Sea of Stars?

Explore a randomly generated galaxy in a starship roguelike built around sessions that fit into a single sitting.

Travel between stars, visit planets, and encounter alien life, artifacts and threats. Find technology to add systems and weapons to a chosen starship, then recruit allies and mercenaries to expand a flotilla. Encounters with alien groups can lead to trade or combat. The setting begins in the Glory star system, where the Terran colony of Hope has discovered faster-than-light travel. Each playthrough creates a different game world, with varied items, alien groups and special encounters. The game continues the Infinite Space series, following Strange Adventures in Infinite Space and Weird Worlds: Return to Infinite Space.
