var sound : AudioClip;
var myText : String = "47 years ago a unique patient in a robotics testing facility escaped." + "

" + “He was called patient 21. You are that patient.” + "
" + “Your have been in sleep paralysis since 2006. It is now 2053.” + "
" + “Feel free to explore this god forsaken world, but let me tell you. Things arent the way they used to be.”;

function Start () {	
    TypeText ();
}

function TypeText () {
    for (var letter in myText.ToCharArray()) {
        GetComponent.<GUIText>().text += letter;
        if (sound)
