About Interstellar Espionage Inc.

Become a spy master and manage a systems-wide interstellar agent business. Manipulate a corporate network by stealing and selling data and technology to become the richest operative in the galaxy.

  • 3 different characters with versatile strategy affecting attributes

  • A vast corporate network that develops according to your operations and data sales

    • Bankruptcies, liquidations and stolen bases

  • Retaliations from corporations against your operations

    • Agents destroyed, vendettas issued and operations blocked

  • Dozens of technologies to steal and develop

  • Randomly generated universe where each run is unique

Focus your tactics and strategy with your character choice. Spymasters develop relationships easy with corporate CEOs with betrayals causing a quick fallout. Cryptographers are more powerful in combined operations, while crackers work from the shadows, receiving less bonuses but also less penalties from corporate actions.

Explore a randomly generated universe with your trusted probe. Find planets, asteroids and space stations. Expand your empire by building relays, operations hubs and admin centers.

Launch operations from your hubs, target planets and their corporations to steal their data. Target corporations with multiple agents to maximize your success.

Sell the stolen data to the highest bidder - or keep the data to yourself to keep a corporation from gaining too much influence.

See your data go to good use as you change the corporate landscape by strategic sale of information.

Find and steal technology, develop it and put the technology to good use - spying!

Make enough money to earn your retirement on a private planet - or end up failing and bumming it on a cheap asteroid with your space dog.
