About this game

Starcom: Unknown Space overview

Starcom: Unknown Space is an action adventure RPG of space exploration, ship building and fast-paced tactical combat. Enter a vast open-world universe filled with alien factions vying for power, strange worlds to explore, mysteries to investigate, and a sinister enemy that threatens the galaxy with an ancient power.

Explore

Explore a fully-open world universe with over a hundred star systems filled with undiscovered planets, mysterious artifacts, lost derelicts, and strange phenomena. Over 230 anomalies to investigate, each uniquely illustrated and with their own story.

Build Your Starship

Transform your small scout ship into a powerful starship of your own design with an innovative shipbuilding system. Make a deep space explorer, a fast strike craft, or an armor-leaden battlecruiser. Experiment with different designs and share your blueprints with others.

Discover & Research

Every new scientific discovery grants Research Points allowing you to unlock new modules and enhancements with a deep technology research tree. Choose techs that favor your preferred gameplay style: Upgrade your plasma cannons or unlock long range missiles? Better armor or shields? Unlock crew specializations first or a larger hull?

Make Allies & Enemies

The galaxy is full of unique alien factions each with their own motives. Decide who you will trust, trade with, hire, or vaporize.

More Features:

  • 60 main story and side-quest missions to discover
  • Train your command crew to improve their skills and ship management bonuses
  • Smart autopilot to known locations, discover fast-travel gateways to distant systems, or venture into the unknown void
  • Alien factions will change their disposition and behavior depending on your actions
  • Collect, analyze, and trade over 100 different artifacts

    Hi, there are some hotfixes available on steam I suppose this is also true for the gog version. I would be happy to see this on here, because I experience a lot of crashes. Thanks.
