Splinter Cell

If you have someone chasing you, run out a door, and when it closes, stand in front of the door for awhile. The guard will sometimes try to open it before he gives up. Note: The door must open towards you, and not towards the enemy. The game can crash sometimes when you do this. If the guard starts shooting at the door, you must open it quickly. Otherwise, the game will glitch and you will be invisible to the enemy and no event triggers will start.

Slowly go up to a Wall Mine. It will flash red and green at an even pace. To disable this, you have to press Action when it flashes green. If it becomes red the instant before you press Action, it will explode. The way to always do this safely is to hold Action button when the "Disable Wall Mine" selection appears. Then, if it is green, release the button. If it is red on the screen, move the selection up to "Back To Game" and try again.

If jumping at a place that is a long way down, you will probably die or get hurt. If there is a guard nearby, try to jump down on him so that he takes the damage. Note: You can go into the silent drop while hitting him, so nobody will hear him scream. If there are no guards nearby, go into the silent drop, and when you touch the ground, quickly hold Jump. If done correctly, you will only get about 25% of the damage that you would normally receive by such a drop. You can also land quieter by pressing B (Crouch) immediately before you hit the ground.

Take a sticky camera or smoke grenades and throw it near where the most guards are located. For the sticky camera, a control bar that tells you how to make a noise or use smoke will appear at the bottom of the screen. Throw the smoke grenade and the smoke should knock out some guards. When the smoke appears from the grenade(s), it is your chance to run for it.

When using the manual lockpick, instead of rotating it slowly as the game suggests, press the Analog-stick in one of the four diagonal corners, as the "rumble" will always be in one of those directions. This is much quicker.

If you are pinned down by a turret, throw a flare across it. The turret will be distracted for a moment, which may be long enough for you to sneak behind it and disable it.

When your in the police station where the jail cells are, go up to the wall and do a wall split.There then should be a light in front of you fall towards it and you'll climb up the light. This is a fun glitch to do.

You cannot be seen when hiding in dark places. Shoot the lights to make it dark, but make sure that there are no guards around. Do not stay in the light too long.

After you have disposed of enemies in an area, make sure that you still hide them, even though no one is nearby. Before going to another checkpoint, the alarm may ring, and it will say that a body was found. Try to hide all bodies in hidden areas for best results.
