In Mission 6: Okhotsk, Russia Part 2, after talking with the Captain he will reveal that he has rigged the bombs to go off. Emile Dufraisne will tell 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 from the controller. When you select the wire the Captain will say that you now have three minutes. The rest of the bombs are located in the machine towers (two of them) and one is upstairs roughly opposite of 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.
