With that courier mission!...every time I attack they leave...what can I do?I've tried sneaking but that doesn't work either because the gaurds always finds me...PLEASE HELP!!!!
I assume you mean the 'Meet the Courier' mission.
I've beaten this game several times on varying difficulties so I'll lend you a hand, I love this challenging (sometimes frustrating) game! It makes you think and use your head, the smart man's game...
From the start grab all the stuff at the starting point, arm your pistol and crawl under the nearby dead truck. You should see a NKVD with his back to you, shoot him in the head then his buddy one block down with the sniper rifle. DO NOT approuch the next guy as one guy will emerge from the side street with a grenade and one hit can kill you. Turn LEFT and watch for the sniper on the balcony of the destroyed 2-story building, kill him.
Go back to where you killed the second guy, approach carefully...even toss a grenade into the alley, you do not want that guy to get a grenade off. Two or three more MG Ruskies will approach, kill them all.
Approach the redezvous point carefully, you should see a wrecked car. The courier's next to it...dead. You'll flip him over and find a map.
You'll receive a new goal: Head toward the square.
Let me know if you need anymore help, your welcome
