# Civ 6 spies: how to use them effectively

> Civ 6 spy guide: unlock spies with Diplomatic Service, siphon funds, steal tech boosts, keep a counterspy at home and promote agents through missions.

In Civilization VI, spies pay off most when you match missions to district targets: siphon funds from rival Commercial Hubs, steal tech boosts from Campuses, and sabotage production in Industrial Zones. Keep at least one spy at home on counterspy duty in your most valuable district, and level your spies up through successful missions so harder operations become possible.

## Getting spies

Spies unlock with the **Diplomatic Service** civic, and later civics and some buildings raise how many you can have. A new spy travels to a city and then must be assigned to a district for each mission.

## Best offensive missions

- **Siphon Funds** (Commercial Hub): steady gold, good for early agents.
- **Steal Tech Boost** (Campus): gives a free eureka, strong for science play.
- **Great Work Heist** (Theater Square): steal art for a culture game.
- **Sabotage Production** (Industrial Zone): slows wonders and units.
- **Recruit Partisans** (Neighborhood): spawns rebels in enemy territory.
- **Disrupt Rocketry** (Spaceport): stops a rival's science victory.

## Tips for success

1. **Pick weak targets:** cities without strong defenses and far from enemy spies have better odds.
2. **Choose escape routes** carefully and mind the level of enemy counterspies.
3. **Promote smartly:** promotions improve particular missions, escape chances or travel.
4. **Defend:** a counterspy in your main Campus or Spaceport can catch enemy agents.
5. **Use diplomacy:** captured spies can be traded back through deals.

## FAQ

**Can you execute spies in Civ 6?**

**What happens if my spy is caught?**
It is captured or killed, and the target civilization may become angrier with you.

**How do I increase spy success in Civ 6?**
Use higher-level spies with promotions that match the mission, target cities with no enemy counterspy, and avoid the hardest missions until your agent has leveled up.

**Which civ is best for spies?**
France under Catherine de Medici (Black Queen): she gets an extra spy and her spies start with a free promotion.

**Can you spy on friends in multiplayer?**
Yes. Human players can be targeted like any other civilization, and they can catch your spies with counterspies.

**Are spies worth it in Civ 6?**
Yes, especially for stealing tech boosts and stopping a rival's science victory late in the game.
