Scouting allows you to gather information about player cities and their defending troops, available resources and technology bonuses. You can also scout mines to find out how many enemy troops are gathering resources on a tile. Tap on a chosen tile and select the Scout button to send out your Scout Drone.

Scout marches require a march queue like troop marches but travel at higher speed.

The amount of information you get in your scout report depends on the Levels of your Spy, Intel and Recon. These levels can be increased by building Improvements in the Scientific District.
