Tom Clancy's Splinter Cell Chaos Theory

The bonus objectives in the Lighthouse are weapons crates Fisher can identify using electromagnetic vision.

The empty jail cell past the cave with the diesel generator.
The tunnel right before Morgenthal's torture chamber, with a diesel generator.
Past Morgenthal's torture chamber, there are two tents outside; one of the tents has a box.
Below the wooden walkway leading to the laptop referred in Grim's transmission. This small outside area has two guards talking about Lacerda's whereabouts that leads to the cancellation of the Eliminate Lacerda objective.
The small room next to the cannons on the rampart.

The bonus objectives in the computer geek's penthouse are six thermographic cameras that need to be tapped. Note that Fisher cannot hide from these cameras since they can see in the dark. Use nightvision to detect their cone of vision or fry their systems temporarily using the DCP.

Past the half contructed area and the PC with the architectural plans is a small flat rooftop with stairs leading into the rest of the penthouse. Redding will contact Fisher about the cameras here, so the camera in question is rather obvious.

In a portico (small yard on the roof) under a trellis (wood beams overhead). This is past the guard listening to some bad rock music in a guest room.

In a hallway leading to a busted lift. This hallway is adjacent to the living room and camera #4.
In the living room. The tapestries literally shows Fisher the path to take.

Bedroom on the second floor.

Inside the greenhouse on the second floor.

The bonus objectives in the bank are eight PCs Fisher needs to hack into to place fake e-mails. Shutdown the PCs you check to keep track of the ones you've investigated.

The bank's front reception desk.

First floor security room leading to the main vault.

During Stage 5, while infiltrating Displace International, Sam will come across two guards talking about Prince of Persia Warrior Within. It is 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. Because Sam is inside the vent, the conversation becomes difficult to hear.

During the 4th mission The Penthouse, when you get near the spiral staircase, there will be a TV which has Splinter Cell showing.

Sticky cameras may be reused in almost any mode as long as they are not destroyed by gunfire or did not use their gas attack.

In the final section of the DPRK missile base, Fisher has 3 minutes to stop the missile. From where the missile launches, head right and down into the door to the command center. The abort codes are on the PC to the right of that door. The codes must then be entered in one of the missile command center's PCs, which are the two rooms near the large elevator (lift) leading to the base commander's office on the level above. Assuming you took out all the enemies in that area, the three minutes are more than enough time to abort the missile.

While your spy (mainly Fisher) is standing and adjacent behind an enemy, hold the Left Trigger to deliver a non-lethal punch that transitions to the fireman's carry. This move will still cause mission failure if the person is to be kept awake or alive for an objective.

The tanks you face in Solo Mode are rather tough but they move in preset patterns. Down the gunner sitting in the turret, then watch the tank's gun. When it aims away, that's your cue to move by or above it. The only way to destroy a tank is to throw a frag grenade into the gunner's hatch. Quicksave to make sure you don't squander your grenades.

In the level Displace International, go all the way to the top floor which has a sole room. In that room is a door that leads to a small closet like area that has nothing in it except for a table with a newspaper on it. Zoom into the newspaper with your goggles to see a picture of some of the programmers and text.
