Counter-espionage is destroying enemy Espionage Probes that are trying to spy on your planet. Your chance for counter espionage is determined by:

  • Difference between both players' espionage technologies.
  • Number of Ships on the spied planet (More Ships => Higher %)
  • Number of Probes sent to spy on planet (More probes sent => Higher %)
  • Random factor added in

Destroying an enemy's Espionage Probes by Counterespionage does not stop the probes sending their information. The information will still reach your enemy even though their probes were destroyed.

The formula used by o-tools is:

2E-O*S*F*0,25% Where E is your enemy's espionage level, O yours, S your probe quantity and F its fleet size
