the game my roommate got is legal. the guy just didn't know any better, got the game from the back and sold it.
the name of the night map is Nelson Bay. Very cool, it's pretty dark but it becomes lighter if you look through a scope. Not sure about looking down the sights though.
One thing I think was a stupid decision was the unlocks for the medic class. Right away, you don't have access to anything as a medic except you gun. You need to level up to unlock the medkits and level up again to unlock the revive paddles. Without the ability to heal/revive, what's the point of being a medic?
