Know the target before committing the fleet.
Improves probe stealth, report depth and your advantage against enemy counter-intelligence.
Espionage Technology makes each probe harder to intercept and compares directly against the defender's tech. More advantage means cleaner reports and fewer blind attacks.
Safer espionage, deeper reports, Espionage Probes, Science Ships and invasion intelligence gates.
🕵 More detailed spy reports, harder to detect probes.
Research time depends on the Research Laboratory level, the Intergalactic Research Network and the universe speed.
Each level multiplies the previous cost by ×2, so each further level gets steadily more expensive the further you push it.
