here is a sample...
QUICK WALKTHROUGH
=================
• When the guard enters your cell, kick his sorry ass for his imprudence.
• Leave and crawl over to the small office area. Using the cigarettes,
distract and punch both the guards in here. Collect your pistol from the
box then go into the corridor again.
• Open the other cell door to meet your team again. Now head out of the back
door and eliminate the enemies in this cluster of rooms. Collect all your
guns back then head down the ladder.
• Clear out the long corridors of the sewers using all the methods of ambush,
sneaking up, distraction and so on. At the first ladder you will meet your
comrade the Spy. Make sure that as you explore the sewers you don't climb
any of the ladders to avoid detection above ground. Also, don't be too slow,
as you are under a time limit.
• Send your men back to the ladder where you first met the spy. Send the Green
Beret out first to silently kill the patrolling guard above the manhole
then enter the house and dispose of the soldier. Send the others out to
join him, one by one.
• Now set about emptying the house. It shouldn't prove too hard, with ambushes
and stealth on your side. Don't forget to take one officer uniform for the
Spy.
• Exit the front way and kill the two Gestapo guys. Send the Green Beret
underground again (the same manhole you came out of) and surface
opposite the central building where you saw the troops assemble in the
cut scene. Carefully kill and drag the patrolling SS Agent behind the walls
of the podium and, while avoiding the patrols, incapacitate both enemies
standing opposite the entrance to the house. Now return indoors.
• With the Spy, head out of the back entrance disguised as an officer. Avoid
the eyes of all Gestapo and other officers, and go to the work site in the
south west corner of the map. When you get the opportunity, as the officer
here is looking the other way, take the bomb from the box and return home.
• Get the Sapper to place the bomb in the middle of the staircase room
(which leads outside to the front garden) then hide in the little space
under the stairs. With the others, clear out any bodies and get behind the
door leading into the room from the back. Cover the door with your best guns.
• By now General O'Donnell's escort will have arrived. The first few guards
will check the room where your men await to gun them down. As soon as the man
himself enters the main room (you'll know because the Sapper is hiding there)
detonate the bomb to kill him and nearby guards. The time limit is over.
• With the disguised spy, leave the back way and head for the German car on the
east side of the map. Stealthily kill any guards on the roof of the building
next to it.
• Send your other men to take out all everyone in your way as silently as
possible then put everyone in the car. Phew! It's over.
enjoy.
