Bomb defusing in Okhotsk, Russia Part 2
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.

Defeating Emile
Make sure you have a flash and frag grenade and full life. There is a lifebox near the door outside of where Emile is on the right wall. Go outside to Emile and an intermission sequence will begin. Once it has finished, 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 then 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.

JBA HQ Part 2: Enrica ends mission
On the "JBA HQ Part 2" mission there are a certain number of optional objectives, one of which is to gather information from Emile's safe. If you do this successfully you must leave his office. The only ways out of his office are through the door (risky as you have a better chance of getting caught) or out into the courtyard. The issue with the courtyard is that there is only one way to get back into the headquarters, through Enrica's window. Before you enter the room, check the map. Notice that Enrica is in her lab working on the other end of the complex. However as soon as you choose to enter her room through the bathroom window, she will instantly appear in the doorway and attempt to scold Fisher. Fisher then proceeds to make a move on her and she lets him off with a warning "Next time, bring flowers", ending the mission.
Kinshasa: Extended level
At the end of the ninth mission, Kinshasa, when you have a sniper to shoot Hamza Hishima do not shoot him. If you do you will complete the mission. If you do not, the crane you are on will fall down. Then Emile will yell at Sam for missing Hishima. Sam angrily turns off his radio and the level in now extended for several minutes.
Mario logo
