The world is under nuclear attack.
Use this map to save the world!
Only catch is... it doesn't have any names on it.
Can we count on you?
A city will be attacked
Find it on the map before time runs out
Double-tap to place a shield
A protective circle will appear on the map
If the bomb hits the shield, the city survives.
If it doesn't, it explodes.
And you lose 1 life.
Repeat until you've saved the world!
Or until you run out of lives.
