Increased levels of Spycraft increase your speed at Sabotaging enemy Turrets (stops them firing) and Cartostations (removes your icons from their map), and Stealing research and resources.

You can go invisible using Stealth if you have at least one star of Spycraft proficiency. Higher Spycraft, longer Stealth time.

The cartography station stores the team's view of the map. Return there from time to time to share where you've explored and to receive what others have explored.
