Great single player and fun multiplayer....
Single player is fun and you get to discover lots of different and interesting stuff about the game. Also by using a knife in single player or multiplayer you can assassinate anyone you want. And you can carry four weapons at a time. You can also carry two weapons in both hands.
Graphics aren't so bad they're okay. I would say 8/10. But overall it's a fun FPS with a different type of gameplay.
