In general, Buildings cannot be bribed. However, if an enemy building is caught in your territory, such as via border expansion or military buildings in the radius of your recently assimilated city, they can be bribed. This also applies to enemy buildings under construction in your territory; you can then choose to complete them or cancel them for a refund of the unused resources.
When a Spy is ordered to bribe an enemy unit, she will approach the target unit and coins will appear around the spy. Most units can be bribed from a distance, but Generals and Artillery Weapons require the Spy to stand right next to the target. If the action is successfully completed, the target unit permanently becomes a unit of the Spy's nation. If the action is aborted or the target is killed before the Spy could complete her action, she is refunded 1000 craft.
It is possible to convert units even if this exceeds the bribing player's Population Limit. Converted units do count against that player's population cap.
- Bribed units usually draw enemy fire immediately after converting and often are killed. This makes bribing basically also suitable for distraction while your units can either retreat or find other ways to work around enemies.
- A large number of spies can greatly weaken an enemy army.
- Take spies with your army. Having them bribe enemy units in the heat of battle not only weakens the enemy army and strengthens yours, but also ensures the spies' survivability because the enemy will be focusing on your military units. To counter the enemy from doing this, take a Scout or two with your army to detect the spies and Counterintelligence them.
- Try to bribe units with a higher importance, such as Generals and Artillery Weapons. This can also be used as an defensive action against early enemy raids.
