Espionage

Observe an enemy planet without fighting. The precision of the information depends on your Espionage technology compared to the defender's.

Espionage

The espionage mission allows you to observe an enemy planet and extract information from it. The quantity and precision of the information revealed depends exclusively on the difference between your Espionage technology level and the defender's. No other factor (buildings, defenses, fleet size) plays a role.

Calculating the espionage difference

The difference determines the precision level for each information category. The higher it is, the more accurate the collected data.

Difference = Attacker Espionage − Defender Espionage
  • Attacker Espionage — attacker's Espionage technology level
  • Defender Espionage — defender's Espionage technology level
  • A difference ≤ −5 results in a completely empty espionage report: no information is revealed.

What do ranges mean?

When information is not exact, a range [min, max] is displayed: the actual value lies somewhere within that interval. The smaller the range, the more reliable the estimate. The size of the interval also depends on the defender's score: a stronger opponent gives larger ranges in absolute terms.
