It's title suggests the obvious, Perfect.
This game started it all, In-Depth FPS, vast amounts of weapons, seconday and tertiary weapon fire modes, intense Multiplayer, Bots, Giving commands to teamates, character customisation, 12 players all on a Nintendo 64.
It is the bible of shooters
worship this game and you will never design a bad game
Perfect dark is the APEX of shooters, nothing compares to its greatness, i have yet to see a game to rival it.
Play the game for yourself if you want to know what its all about, the problem with going back to a great game after all these years is that framerate issues and oldness just makes it seem lame.
If you were there when this game was released you will know that it kicked goldeneye square in the balls.
it was just that good.
