So when I played the Terran campaign again after completing the Zerg campaign in Heart of the Swarm, I accidentally uncovered a secret maybe? The one I'm talking about is in the mission where you have to hold for about 20 minutes on the first planet. There is a soldier that will go to a toilet when you see him, then will blast off when clicked three times. So
Are there any more of them in the other missions?
What does it do? Does it gives any accomplishment or anything at all?
