Your mission is to chart the long-abandoned Serpens Sector, a region of space reached through a wormhole near Earth. Each star system you visit brings you an encounter with something - aliens, ancient ruins, other humans and many dangers.
Example of the subtle background sounds in my game, Space Exploration: Serpens Sector. I've amplified the volume - in-game, this is much quieter. The effects you can hear in this example include ship sensor sounds, intentionally incomprehensible conversation snippets, asteroid showers and radiation spikes - and at the end, a SOS signal from a nearby star system.
