Sea of Stars continues the Infinite Space series of games that defined the genre of short-form space roguelikes in Strange Adventures in Infinite Space (2001) and Weird Worlds: Return to Infinite Space (2005). It compresses a galaxy-spanning starship adventure into the space of a single sitting, but as the game world is randomly generated each time you play, you will keep coming back for more. There is enough variety in items, aliens and special encounters that you will always discover something new - no two sessions play the same.

Sea of Stars begins in the Glory star system, in an area of space known as the Purple Void for its colorful nebular clouds. The long-isolated Terran colony of Hope has discovered the secret of faster-than-light travel, and an age of interstellar adventure has begun. Choose your starship and blast off into the Infinite Space in search of fame and fortune! Travel from star to star, explore planets and discover strange lifeforms and artifacts left behind by ancient empires. Find technology to upgrade your ship and gain allies to grow your flotilla. Encounter bizarre and delightful alien races, trade with them or blow them up - the decision is yours. And sometimes, you will face an existential threat to all life in the sector, and get to save the world.
