So answer your EPF phone and head over to the security room!
One year ago, the Earth Day event was nearly attacked by an evil robot named Protobot. Thanks to Herbert, we stopped him. Herbert isn’t likely to attack, but we need to expect the unexpected. Provide security and scan for signals. Just in case.
Well done, Agent. You’ve picked up an unusual signal… The message is blank, but it’s definitely encrypted. Why would someone send a blank message? This is very strange. Stay on alert-this may be an important clue.
