In the PC version of Ghost Recon hit ENTER in the numeric keypad. Enter the word "ghost". You'll get a message that "Ghost Mode" is on. This renders all enemies invisible. They will still see and shoot you... unless you use Teamshadow. If you do, when close enough to the invisible enemy you can hear them talk, see their shadows, but they don't become visible until they are shot. Welcome to Wonderland.

By typing squirrelkite after hitting the enter ket on your number pad, your grenades turn ito squirrels. Hillarious!
