At the beginning of the last mission, Sam will encounter a metal door that is opened using the switch to your left. Before opening the door, look through the windows ahead of you. When the guards show open the door. They won't see you, but they should investigate. As they go back into the corridor, shoot them with your pistol for two easy kills.
At the beginning of the last mission, you will encounter two guards in a large corridor. After taking these out (avoiding the camera to your right), make your way to the end of the corridor. At the end there should be a vent to your right. After crawling through the vent you should come across a set of stairs. Follow the path and climb the wall at the end. You should see a guard facing away from you and another guard mopping the floor. Take these out with your SC-20K and make your way to your next objective from here. This way helps because you skip several guards which means you save a bit of ammo.
In order to get a 100% rating on any mission, you must complete the level with the following statistics. It is unknown at this time if there is a reward for getting a 100% rating on every mission.
The best equipment to have online in any level is the smoke grenade, sticky camera, optical camo, and alarm snare.
If you trigger alarms, the guards will be more alert and wear helmets. When you have four alarms all secondary and opportunity objectives are cut, and the funny long dialogue is simplified. This is what happens when Otomo tries to commit seppuku. Fisher says "I think someone is taking himself a bit too seriously." Lambert then says "We can't afford to let him die, Fisher. Get in there and stabilize him. Fast!" The following occurs when you have four alarms. Lambert says "Otomo tried to commit seppuku. Get in there and stabilize him, fast." When you have four alarms in a level all the funny conversations are replaced by one person giving a monologue.
Moving faster in water
In any mission when you are in water, take your gun out. You will move faster.
Bathhouse: Finding the bombs
After going through the gate when chasing Shetland, the first bomb is directly to the left of the gate that you enter. Go left through a little crevice and you should see a red light flashing. Go to it and disarm it. When you do that, one of Shetland's gaurds will walk up the stairs. Kill him. To get to the second bomb, go up the stairs. Turn left then turn right and look straight ahead. You should see another red flashing light down below the walkway. Hop over the ledge of the railing and disarm the second bomb. When you are done disarming the bomb, jump on to the railing and pull yourself up. Two guards will be to your left, walking on the walkway. They will probably hear you; get ready to kill them. It is fairly difficult to kill them without losing a lot of life, or at least dying. After you kill them, go down the walkway to the back wall. About halfway you will see another red flashing light. Jump across the little gap and disarm it. A guard will come through the back door right when you disarm the bomb. Kill him, then go through the door and meet Shetland. You will then have to make a critical choice; note: pull the trigger. It would be a good idea to quicksave the game whenever you disarm and kill the guards.
When you are on your first mission, 'Lighthouse', you will need to make it through a small pathway with bats inside. Make it through here until you reach a bridge. Using thermal vision, you will be able to see two enemies at the opposite end of the bridge. Instead of going across the bridge, go to your left to find a ramp that goes underneath the bridge. Going through here will lead you to some ladders. Climb the ladder and you will make it further into the mission without encoutering any enemies that may cause trouble.
Alarms - Lighthouse
On this mission, there is a small camp set up for terroists. The camp is not permanent so there is no alarm system. This means you can go in as loud as you want without setting off any alarms.
On the first mission, there will be a man talking to a fellow terroist about how is family got killed in a storm. Wait for him to finish his story and the two men should walk into a puddle. Get out your shock attachment for the SC-20K and shoot at the puddle. This will kill both men in one shot.
If you move around with your gun drawn, the noise meter will not move. This is very useful when sneaking up on someone quickly.
Defeating ISDF guards
In any mission where you must deal with an ISDF guard, you cannot knock them out with gas. Try using a shotgun.
In order to do a better ledge grab, press A, then when the spy puts his legs up on the thing he is hanging from, press Forward while tapping A.
Have your sniper zoomed-in on the guard. When there is a fight, shoot, run, and catch Shetland. Then, end the mission.
Seoul: Destroying the tank
In the very last area of the second part of the mission, you can rescue the injured pilots as a bonus objective. However, instead of waiting for the lamp to flicker on and off to get past the tank safely, there is an easier way. Make sure you have a frag greanade (obtained elsewhere in the level). Go to the very top of the scaffolding and take out the frag grenade. Aim the grenade to go in the hatch of the tank. If done correctly, the grenade will explode in the tank, which will destroy it. You will no longer have to deal with tank gun.
Penthouse: Bouncing guard
On the ground floor after you have knocked out two guards (the one who is repairing the elevator and the other one that is talking to him), put one or more of the guards in the elevator with Sam. Sam must turn on his night vision and press the button tob go to the top floor. Watch the guard's body bounce around like popcorn.
Lighthouse: Alternate way to retrieve the radio data
During the mission you will have to overhear some data being said on a radio transmission by a guard. If you fail to do this, you can just find the data in a filing cabinet next to the radio.
Aquarius: Killer area
Go to the pirate room, then go to the left. Go to the little hallway to the Techroom. When you are on your way (if you are still in the hallway) look to one of the sides to find a little box area. Crouch into it. If someone presses the button on the outside, the area will be closed and you will not be able to get out. If you stay there too long, the area will fill up with water and you will die. The only way to stay alive is if someone presses the button again and the water drains out.
Bank: Invisible laser beam
To avoid detection by the invisible laser trip wire in the entrance of the vault, closely examine the entrance with your thermal goggles on. Then, use your OCP to disable the laser emitter and walk out of the vault. By doing this, you can leave without sounding the alarm.
Penthouse: Ubisoft references
In the introduction sequence for the mission, when you see a blimp, you can also see a Ubisoft logo on it.
North Korea: Ronald Reagan
This game was developed at about the same time that Ronald Reagen died. In the missile battery stage, a missile is launched at the USS Ronald Reagen. Grim tells you this and Sam says "You want me to win one for the Gipper?"
North Korea: Half-Life
In the missile battery stage, at some point Sam asks Grim if he could use a crowbar to open the console in the battery. She says "That's for geeky scientists". This is a reference at the Half-Life games where you play as a scientist with a crowbar.
I-SDF Base: Metal Gear Solid
When you get to the lower floors in the I-SDF base, interrogate a guard. Sam will ask him about his LTL (less-than-lethal) weapon. The guard will tell Sam that the ammunition is some kind of electric round. Sam asks where he can find some. To this the guard replies: "It's not like you can shake me, and make my ammo drop on the floor". This is a reference to the Metal Gear Solid games, in which you can do just that.
I-SDF Base: Splinter Cell
You can overhear a couple of guards talking in the main hall. One will say something about how guarding the place is just like guarding the CIA HQ; nobody would break in there. This is a reference to the original Splinter Cell, in which you must break into CIA headquarters.
Hokkaido: Bill Gates
There are two guards talking about their new vehicle. During the conversation, one says that it has a 640 gig MP3 player, "standard." The other replies that no one will ever need 640 gigs. This is a jab at a comment made by Bill Gates back in 1981 about no one ever needing more than 640 K of RAM.
Hokkaido: Splinter Cell
After you scan Milon Nedich's liscence plate and enter the building, you will overhear some guards talking about ninjas. One will be telling the other that he was stationed on an oil rig and that it was attacked by a ninja. This is a reference to the first Splinter Cell in which Sam is the ninja.
Displace: Prince Of Persia: Warrior Within
While infiltrating Displace International, Sam will encounter two guards talking about Prince Of Persia: Warrior Within. It is in the small cafe next to a laser filled hallway, past a keypad locked door. A second way to access the room is through a vent. However because Sam is inside the vent, the conversation becomes difficult to hear.
Bathhouse: Splinter Cell
You must go through the warm baths at one point in the level. There are two guards here. Interrogate one of them and he will tell you that Shetland's elite guards have thermal goggles. He will also add that they will not do much good in steam, because steam is not fog, as in an abbatoir. This is a reference to the original Splinter Cell game, in which Abbatoir is a level.
