Defeating Emile
Make sure you have a flash and a frag grenade and full life. There are a lifebox near the door outside of Emile on the right wall. Go outside to Emile and an intermission sequence begins. When it is done, on your left may be a laser beam. Wait for it to go off. When the laser goes off and Emile is done shooting (he will begin again), roll to the next chair or bench. Wait until he is finished shooting again. Continue doing this and go up for the fence/rail. Jump onto it. Go down from it and you now must take Emile out. Walk away for one or two seconds, and make sure you can drop the flash grenade near Emile. Shortly after it is dropped, put your frag grenade in the same place. Emile will not see you drop it and will be defeated. Then, read the computer and defuse the bomb. Note: Take your time.

Okhotsk, Russia Part 2: Bomb defusing
In Mission 6: Okhotsk, Russia Part 2, after the talk with the Captain he reveals that he has rigged the bombs to go off. Emile Dufraisne tells you that they are in the machine room. Look for a crawl space near you. Go through it and down the ladder. Once you are in the machine room, disrupt the light near to the ladder with your OPC and the camera that you will find nearby. Then, go to the first bomb (you will recognize them by a green light) on the same level as you are on. You can defuse them by cutting the wires in a particular order. The wire you have selected for cutting will be highlighted in green You will know which wire to cut by a short vibration in the controller. When you select the wire the Captain will tell you now have three minutes. The rest of the bombs are located on the machine towers (two of them) and one is upstairs roughly opposite the first bomb. Note: There are three guards in the room. It is recommended to quick save the game before attempting to defuse your first bomb so that you have an idea of how it is done.
