In the XXXI century the Earth goes through a space-time storm. The consequences are catastrophic! The particle known as RZ-800 is responsible for maintaining integrity of the entire galaxy. Without it, billions of stars, planets and intelligent life were extinguished. And that's what it's going to happen, as the storm has shifted it into the past. If the particle is not returned to a certain time of the space-time continuum, the galaxy will collapse IN ALL THE TIME LINES!

Your mission, soldier, is to find the particle at all costs and return it to its natural place. It's your responsibility. Because you're Mini Explorer XXXI.
