Time Lapse

          Scientist have done it! A time-Machine has been created. What should they do first? In an experiment, everything goes wrong. The Time-Machine explodes sending ripples through space-time. The whole city is destroyed but one mere man box thing. The area in which the city resided has been sent back in time, trapped in an era no one knows.

          Someone wanders into the legendary city not knowing what might happen. This sets off a gigantic ripple through all space and time. Everything outside of the city is advancing acceleratingly faster. Enemies come into the city to take something? But what? Who? Why? Even they don't know. Just the fact of the phenomena that has resided here is enough reason to invade. 

          Fight off enemies. Progressively get better weapons and materials from their accelerating progress in technology. Build your base and stop them from destroying you. For some reason you know that if you die, everything will become nothing. All space and time will be destroyed forever if they succeed.
