Spies

[Enraged]

what building makes spies? I noticed when I dropped dens,, that I started losing spies.

Are spies a necessity?

[Slasher]

they are if you want to be doing a spy/whatever its called now strat or if you don't want to be hit with spies. They can also be uses to get other peoples statuses so its just similar to any other troop really

Even if you aren't doing a spy strat...its a good ideas to have some for protection.

I typically have about 10% of my buildings as Dens.

Dens make spies, and they are important to have. Without spies you will never be able to attack people in different areas (Europe, North Africa, Middle East) you can't cast shields to protect you from enemy spies, and you can never scan anyone else (not terribly important).

Dens will make spies as long as you have fewer than 100 spies per den, and you will lose spies if you have more than 175 per den.

Once you get a good amount of loyalty, you'll only need a maximum of one spy and one den to raise defenses and prepare expeditions.

Like in Civ...If I catch someone trying to put spies in my empire. I just nuke them. I try to aim for 3-4 global warmings in one turn.
