"The enemies in Middle-Earth: Shadow of Mordor are special.
The angry, slimy, war-mongering orcs aren't just grunts the player kills to level up (although they certainly can be, if that's what the player wants). The enemies can be useful to the player. They can act as an intelligence resource. They can serve as minions. And, sometimes, they might even have a history with the player. No two orcs are the same, and no two players will have the same encounter with the same foes. The villains, as Shadow of Mordor's director of design Michael de Plater says, are personal."
