I don't have idea why have they rated it so bad....
Well, I bought it and I was quiet surprised. The game was awesome!!"
The Sniper: Citing from the game: "My name is William Hawkins, I am a sniper, one of the best." You can slow down time to shot better, throw knives at germans or simply do a stealth kill with a knife.
The Spy: Citing from the game: What he says, goes." He is the captain of the strike force. You can take enemy uniform and travel with it without being spotted by the enemy forces. The higher ranking uniform you have, the harder they discover you. The uniform with the biggest ranking is the gestapo uniform, only other gestapos can spot you if they take a longer and closer look. The Spy can also stealth kill with a wire (probably fiber), and he can throw coins to distract enemies so you can pass by somewhere without being interrupted.
The Green Beret: Citing form the game: "He is the muscle, but not stupid muscle like, clever one." His main weapon is Thompson, and that says it all. He is more the heavy shooting type, not a stealth guy but he is still awesome. There has to be someone to bring the adrenaline up :)
"We are the Strike Force, the enemy fear us, and so they should."
