7. You can just make it to the left of the fire, or you can simply jump over the railing - your choice.

19. Slide open this painting and use the computer inside to find Blaustein's black box and complete the objective. You'll also receive a data stick with the access code to the back door: 091772.

20. Turn around and enter the code 091772 into the keypad to exit through the back door.

33. Gurgenidze's dead drop is through this secret passage. A box of ammunition is in the dark corner directly ahead. (Thanks, Elliot!)

34. Use the computer to get the police station access code - 5929. Note the medical kit on the wall to the right. Another is on the left wall.

48. Using your optic cable on the next room reveals a guard - best to leave him alone.

49. Interrogate this guy with the very cool Space Invaders T-shirt. Hide the body behind the shelving in the previous room. Return and grab the medical kit from behind the curtain.

53. Listen to their conversation, "Next window, please," T'iblisi-style.

54. Sneak behind the vertical blinds, then past the civilian and out this door on the right. Or you can just kill them both -- you'll find a medkit and a computer in the guard's station.

55. You'll find this room at the top of the stairs. If you are quiet, you can knock out each guard and the other will not notice. You'll find computers behind doors 1 & 4. Door 2 has a dead interogee, and door 3 is your destination - the video surveillance room.

56. Quietly enter the video surveillance room and knock out the guard. Grab his satchel for a data stick. Use the computer to update your objectives.
