1) Find your spy (the way I showed you before)
2) Move that spy to the colony you want to place an agent
3) Click the colony ->actions ->plant agent
This will cost you 25e so much sure you have the energy (25e meaning 25 energy

Ignore all this if the guy you are trying to spy attack is a guy called GameOver
