All I can say is... wow this is an awesome FPS i think it's the best one on the Wii.You will get sucked into this game.
The nostalgic feeling this game brings when playing the multiplayer is just "wow". I felt like the little kid who always used to go to his friends house to play goldeneye 007 on sundays. Ahhh memories, anyways the multiplayer is nice and fun, the cool customization options are awesome and i love the mods! Paintball, bouncy grenades, and that moving mod or whatever is my favorite combination!
The singleplayer campaign is pretty awesome too. I love the smartphone idea that was awesome, now i get to hack those annoying turrets that made my life a hell when i was a little kid. Anyways the stealth half of the game is fun, while some of the AI is to smart even on the easiest mode, like i'm behind a 10 foot tall and 5 foot long piece of concrete and the enemy is on the other side of it and shouted "ENEMY SIGHTED" and started (trying) to shoot through the concrete. Otherewise I highly reccomend this game.
