Designed to raid spy on enemy asteroids. Also essential in the defense of the player's asteroids against enemy spies.
To get spies, the player can:
- produce them at the Cyborg Factory
- complete quests
The number in the top panel shows the number of spies available on the asteroid. When the reserves are overfull, the number turns red and cyborgs begin to desert (first spies, then explorers, and finally, workers).
