I really love this game, it´s a sequel to Golden Eye but in my opinion Perfect Dark is much better! You play as Joanna Dark, special agent for Carrington Institute.
The game includes “second firing mode” for almost every weapon, which is really great. You also have to watch your step so you don´t fall down from high places, which makes the game a lot more realistic. Another great thing is that if you shoot the enemies in the hands, they drop their guns.
This game is really fantastic and one of my favorite first-person shooter games! :3
