Plot

Infinite Space contains themes from the novel Childhood's End by Arthur C.
 Clarke.[8] The plot is divided into two main storylines; both are centered around Yuri,
 a starship captain-in-training, and take place ten years apart.
The game is set tens of thousands of years in the future,
 when humankind has spread across several galaxies. While faster-than-light travel using
 "inflaton inverter" engines is the standard for all spaceships,
 ancient constructs called Void Gates are necessary to travel wider
distances that would still take years to cross. Ruined, inactive Void Gates
 called Dead Gates can also be found, but are seen as nothing more than scientific curiosities.
 Infinite Space focuses on Yuri's quest to discover the ultimate purpose of the Epitaphs,
artifacts scattered throughout the universe.
