Commandos 3: Пункт назначения - Берлин! чит-файл №1

Clearing out the sewers in Berlin
When you find yourself in the Berlin sewers after the cut scene in which you
meet the Spy, you can easily overcome each room of the sewer and clear it out by
simply using punches, knifing and running into a room, being spotted and then
running out, and taking cover behind your fellow commandos, who are of course,
waiting on guard move with their guns pulled out, aimed at the door. When the
Nazis burst in, your men nail them, and you can clear all the sewers out doing
this. With a couple of the Nazis, it's even easier to simply come out behind
them, knife them and drag their body back through the door.

Sniper vs. Sniper
I completed this level first of all by literally taking out everyone a man at a
time, and boy was it hard going! Then my brother tried it, and discovered that
when you've sniped one nazi from the Russian embassy (be careful, pop out of the
wrong window and the elite sniper will kill you!), and cleared out the Nazi
riflemen around the fountain by sniping them from the unoccupied yard area
(behind the wall, above the little dugouts the Russians soldiers mostly start
in), you can crawl down, take their stuff and then as you move down towards the
highest tower (it's a church building), the elite nazi sniper should move his
position and make a run for it; he tends to respond to your movements to keep
you covered so you can't snipe him but he can snipe you. As he runs, you can
actually quite safely change direction, bolt the other way and snipe him as he's
running - ending this part of the mission early! Whew!
