To conduct espionage and counterintelligence effectively in Civilization VII, it is essential to grasp the mechanics of these systems, recognize how to initiate actions, and implement strategies to protect your civilization from enemy spies. Below is a detailed guide on both approaches:

Conducting Espionage Effectively

1. Unlocking Espionage Actions:
– Research Requirements: Prioritize particular technologies and civics within your Technology and Civics Trees that unlock espionage options. Additionally, some advanced options become available through the Attribute Tree, which you can access by interacting with your leader profile.
– Focus on Outputs: Ensure a robust output in scientific and cultural research. A strong foundation will enable you to unlock sophisticated espionage techniques as you progress in the game.

2. Initiating Espionage:
– Establish Diplomatic Relations: You cannot engage in espionage against a civilization unless diplomatic relations have been established.
– Accessing Espionage Actions:
– Click on the target civilization’s leader portrait, located in the upper right of your screen.
– In the Diplomacy Menu, scroll to find the available espionage actions.
– Choose your desired action, and note that each comes with an Influence cost per turn, which is clearly displayed.
– Duration of Effects: Each espionage action remains active for a specific number of turns, providing covert benefits during that timeframe.

3. Types of Espionage Missions:
– Missions Available: Actions can range from stealing technology to sabotaging developments, and gathering intelligence on enemy activities.
– Reward Levels: Two tiers of rewards are available—Secret (base effect) and Top Secret (which may include bonus units or other significant advantages). Beware, however, that if your espionage actions are uncovered, you will face relationship penalties and loss of Influence.
– Influence Management: Since the success of your espionage is tied to your Influence resource, losing this resource can cancel ongoing missions, leading to potential vulnerabilities.

Conducting Counterintelligence Effectively

1. Unlocking Counter Spy Technology:
– Research Counter Spy: Locate and research the relevant technology in the Civics Tree to enable counterespionage actions that can protect your civilization from enemy spies.

2. Counter Spy Diplomatic Action:
– Initiating Counter Intelligence: Use the Diplomatic Counter Spy action strategically against civilizations suspected of espionage activities against you. This action will lessen the effectiveness of their espionage efforts, extend the time required for their missions to complete, and increase the likelihood they will be detected.

3. Limitations and Prioritization:
– Instance Limitations: You can maintain only one active counter spy initiative at a time, which may present challenges if multiple adversaries are attempting to spy on you. Therefore, it is crucial to prioritize counterintelligence against the most threatening civilizations.

4. Detecting Enemy Espionage:
– Watch for sudden drops in your Influence or unexpected relationship penalties, as these may indicate that enemy espionage actions are taking place.
– Regularly track the espionage actions against you in the diplomacy menus to facilitate prompt and effective responses.

Summary Table

| Aspect | How to Execute | Notes |
|———————-|——————————————————————————-|———————————————————|
| Initiating Espionage | Research tech/civics, establish diplomacy with target, choose espionage action | Costs Influence per turn, benefits are covert for set turns |
| Espionage Rewards | Secret and Top Secret rewards; includes tech theft and unit bonuses | Risks penalties and Influence loss if revealed |
| Counterintelligence | Research Counter Spy tech, use Diplomatic Counter Spy action | One active instance; slows enemy’s operations |
| Managing Influence | Closely monitor Influence; running out cancels missions | Sudden drops often signal enemy counteractions |

By judiciously balancing your Influence resources, advancing your research to unlock various espionage and counter-espionage options, and selectively targeting or protecting against rival civilizations, you can harness the power of espionage and counterintelligence to gain a decisive edge in Civilization VII.
