The only hard part about this level is the hostage rescue. On 00 agent, you must rescue all but one hostage. You start off in a boat with a silenced DK5. This is the only gun you should use on this level! Walk up the ramp, and head left. Keep going straight up the stairs. Open the door, and shoot the guy in the next hallway. Go collect his ammo, the open door next to you. You should see your first hostage. Don't take time to aim, just shoot the guy holding the hostage at gunpoint. Then, shoot the other guy in the room. Don't enter the room just yet! When you enter the room, walk along the wall with an open door in front. Carefully peek out and shoot the guy holding another hostage at gunpoint. Shoot him in the arm to kill him if you have to. Now, a few more guys should come running into the room. Shoot them, but be careful not to blow up the computers. Next, go back into the first hallway you walked through. Head towards the door you came in, but this time, take a left through an open passage. That passage should take you to a door. Open the door, and shoot the guy in the next hallway. Go in to the door in the left, and kill the guy with double phantoms. Open the next door, and shoot the guy there. This room should have some radio-like things in it. Pick up the body armor (in agent and secret agent only!) and open the door. Shoot the guy holding the hostage at gunpoint, then shoot the guy in front of you. Another guy should come running over. Shoot him as well. Be VERY careful not to hit any of the computers! After all three guys are dead, switch to the bomb diffuser via watch and press Z to diffuse the bomb (pressing B will cause the bomb to go off!). Now, there should be four doors on the back wall. Go in the middle-left door. Shoot the men there in the head, and then open the door in front of you. Walk back to where you saved the first hostage, but this time keep going straight. Open the door in front of you and walk down the stairs. You should see the helicopter. Switch to the tracker bug via watch and place it on the copper (you only have one!). Open the garage-like door, and then go up the small set of stairs and open the next door. 3 troops should have their backs to you. Walk up behind each one and plant a bullet in their heads. Open the next door, and shoot the next two guys. Walk down the steps. Two men should be at the bottom, so ice them. Next, open up the door and enter the engine room. There should be a man right next to you. 1 bullet will take care of him. There is another man standing across the way. A head shot will due him in. Aim down, and you'll see another man. Another head shot will due. Now, walk down the stairs, but stay against the wall. Lean out, and shoot the guy guarding a hostage. Shoot the other guy across the room, then go up the stairs on the other side of the room. You'll see two computers and a bomb on them. Diffuse them bomb, then go in the next door. You'll encounter 3 men, but they are no match for your DK5. Next, head down the hallway and open the door. Shoot the guy guarding the hostage. Go down the curving hallway, and you'll see a guy with his back to you with a hostage. Shoot him, and his counterpart, then go up the stairs in the next room. Go back to the copper, then take a left. Go through the next door, and keep following the hallway. It'll lead back to your boat. Another success!
