When there is no place to hide and you lost any hope, salvation can suddenly come out from nowhere.
What happened? Where are all your friends and colleagues? Why there are so many of THEM around? Is this the Apocalypse?
No time to think! The only way to survive now is to run. A helicopter is waiting for you on the roof and your only goal is to get there as fast as you can.
So RUN UP to save your life!
