Then tap quickly to attack them before your monster takes too much damage. Each time you defeat an enemy, your skill improves and, over time, you can increase the power of your summoned monsters! Move from neighbourhood to neighbourhood and reestablished control of the city.
The monsters get bigger and badder. Can you keep up with them? Who will be the ultimate apex predator?
