Also known as "Why did they make this game so sunflower and daisies complicated" is a game about sitting in your lair, committing nefarious acts and torturing agents.
It's very, very complicated, you can't control your minions directly, but the few people you can control can whistle, have heaps of minions crowd around them, and rip the island in-half.
An important thing is not to kill agents, while this may be the more enjoyable aspect and you don't feel like building 100 traps to stupefy them. If the agents don't see anything wrong and go back to base saying so, you get some unsuspicious reputation, so to speak.
Good game, nice and fills your time for a while, also, if you want to know more, Wikipedia is your friend.
Oh, and another thing, it's got an awesome soundtrack.
