that #### train made me freak could not for the life of me figure it out...........but I finally did. You have to sneak around but get out the shot gun sneak behind every guard and knock the sucker on his head he falls to the ground but dont think he is dead hes KNOCKED OUT now get out your knife and knife him. Next got to get insinde the room at the top of the stairs to switch the train on. So get there I finished the game today. So this is not the last time you'll ask for help.........there is alot more like this. But think before you leap cause those guys are all over the place. When you get to the shop level you'll wanna scream.

HELP!!!!!

stuck at bit where I have just dropped down via hole in wall.

Killed both guards no probs BUT.....

Enter room with 2 guards & stairs at far end. As soon as I enter I get spotted & the Siren goes off.

Proberly really daft solution pending here

You have to take them out one after the other. They both have their backs to you. First knife the guy standing then the guy heading toward the stairs. You don't even have to be quiet; you can run right up to them. If you choose, you can knock them out by pistol whipping them (use the secondary fire key for your pistol) but then you must kill them with your knife otherwise they'll wake up and sound the alarm.

yep to that...I found I had to throw a knife at the head without fail, in order to keep the guy from gurgling...
