The alien invasion has begun and it is your job to defend your city. Use the gun to blast incoming UFOs and use the fire hydrant to extinguish the falling fireballs. If a fireball reaches the ground a building will explode leaving the city in chaos. If all of the buildings are destroyed the war is surely lost. You are the city's only hope. Good luck.
I am only 14 years old and this is my 3rd app. Please let me know if you have any ideas for improvement. I hope you enjoy playing Save The City.
