Tom Clancy's Splinter Cell Chaos Theory

If you move around with your gun drawn, the noise meter will not move. This is very useful when sneaking up on someone quickly.

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.

After you scan Milon Nedich's license 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.

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.

To take out lights silently, first OCP the light, then shoot it.

Hold L1 + L2 + R1 + R2 then press Square, Square, Square, Square, Square, Circle, Circle, Circle, Circle, Circle.
