Metal Gear Solid 2: Sons Of Liberty

Getting Dog Tags
Most of the normal guards in the game have Dog Tags that contain the names of the game's development team and those that won Konami's contest. To collect the Dog Tags you must hold up the guard and then make him shake and give it up by pointing your gun at his head or crotch. Dog Tags can be collected for each of the game's four difficulty levels.

Get the Wig
First play through both the Tanker and Plant episodes and get every dog tag. Then start a new game and save. You will then have a wig in your inventory that gives you infinite ammo and allows you to not have to reload.

Get Digital Camera
After you beat the game, you can play the game over with the same save and you'll have the Digital Camera in your inventory for both the Plant and Tanker episodes. You can use this to take pictures and save them onto your memory card.

Extreme Mode
After you beat the game once, you'll unlock the Extreme difficulty level.

Waking up Soldiers
If you need to get a Dog Tag from a knocked out guard, just spray coolant on his face to wake him up and then try to hold him up.
