Ghost City

Ghosts have abducted your city. They are wrecking your city. Everybody is at home, scared. 

You are the city's only hope. With a  gun in hand, you go to the streets. The ghosts spot you. Now all you have to do is kill them.

Ghost spawn unlimitedly and unreasonably fast. Your job is to not lose your health (it is a never ending game). 

Can you do it?

Welcome to Ghost City.
